Can You Regrow Teeth? The Truth About USAG-1, Tooth Regrowth, and What’s in Clinical Trials

Can You Regrow Teeth? The Truth About USAG-1, Tooth Regrowth, and What’s in Clinical Trials

by | Mar 2, 2026 | Dentistry, Tooth Replacements

Can you regrow teeth? That’s the question behind the latest USAG-1 headlines—and the answer is more nuanced than Instagram makes it sound.

If you’ve been on Instagram or TikTok lately, you may have seen someone confidently claim: “Yes, you can regrow teeth — look up Toregem BioPharma and their USAG-1 blocker.”

That kind of statement mixes a real scientific idea with an unrealistic “it’s available now” conclusion. So let’s slow it down and separate what’s credible from what’s clickbait.

This article is a grounded follow-up to the recent wave of viral “tooth regrowth” content (including topical patches and miracle claims). Unlike those trends, the USAG-1 story is rooted in legitimate developmental biology — but it’s still early-stage.

Can you regrow teeth today?

Right now, the practical answer is: not in routine clinical dentistry.

However, researchers are actively investigating whether certain biological “brakes” on tooth development can be lifted to allow dormant tooth-forming pathways to restart. That’s what the USAG-1 research is about.

What is USAG-1, and why does it matter?

USAG-1 is a protein involved in signaling pathways that influence tooth development. Think of it as part of the body’s regulatory system that helps determine when tooth formation should stop.

Humans typically form two sets of teeth (primary and permanent). After that, the body doesn’t normally keep producing new tooth buds the way some animals do. Researchers have been trying to understand whether this “shutdown” is absolute — or whether certain pathways can be reactivated under controlled conditions.

In preclinical research (animal studies), blocking USAG-1 has been associated with additional tooth formation in some models. That doesn’t mean the same outcome is guaranteed in humans — but it’s why scientists consider USAG-1 a serious target for regenerative dentistry research.

If you want a reputable overview of regenerative dental research as a field, the National Institute of Dental and Craniofacial Research (NIDCR) is a good starting point:
NIDCR — National Institute of Dental and Craniofacial Research.

Meet TRG035: what people are actually talking about

TRG035 is commonly described in media coverage as an investigational therapy connected to the USAG-1 pathway. It’s discussed as a biologic approach (often framed as an antibody-based strategy) aimed at reducing USAG-1’s inhibitory effect so tooth-development signaling can proceed.

Important clarification: this is not a topical patch, not a toothpaste, not a supplement, and not something you can order online.

Are there human clinical trials?

Yes — but this is where social media often oversimplifies things.

Public reports describe human clinical trial work beginning in Japan, with early-stage human research focusing first on safety and feasibility, and with longer-term hopes of broader dental use later in the decade if trials go well. Here’s a mainstream dental-industry write-up:
Dentistry Today — Japanese researchers and a potential “third set of teeth” medicine.

In drug development terms:

  • Phase 1 primarily evaluates safety, dosing, and side effects.
  • Phase 2 begins to evaluate whether the treatment works reliably (efficacy), and in whom.
  • Phase 3 compares outcomes in larger groups and supports regulatory approval decisions.

So, if you’re hearing “it’s available for limited use in the United States,” treat that as a red flag. “In trials” does not mean “available in clinics.” In the U.S., legitimate access usually happens through formal clinical trial enrollment, not routine prescription or dental office offerings.

If you’d like to check clinical trials directly, the best public database is:
ClinicalTrials.gov.

Can you regrow teeth in adults with this approach?

This is the key question — and the one we don’t have definitive answers for yet.

Even if a treatment can stimulate tooth formation in humans, dentistry still needs answers to the clinical questions that actually matter, like:

  • Where would a new tooth form (and can that be controlled)?
  • Would it develop a functional root and integrate properly with bone and ligament?
  • How predictable would the results be in older adults vs. younger patients?
  • What are the system-wide effects of changing a signaling pathway that may influence other tissues?

That’s why early trials are cautious and staged. Dentistry needs predictable placement, function, and long-term safety — not just a headline that says “teeth regrow.”

Can you regrow teeth naturally?

This is one of the most common searches after people see a viral video: can you regrow teeth naturally without surgery, implants, or dental treatment?

In everyday clinical reality, the answer is still no. Enamel does not biologically regrow once it’s lost, and a fully missing adult tooth does not spontaneously return. What you can do is reduce risk and slow damage (for example, improving hygiene, reducing acidic exposures, and addressing dry mouth and periodontal inflammation early).

Why viral “tooth regrowth” content spreads so fast

Tooth loss is personal. It affects confidence, chewing, nutrition, speech, and quality of life. So it’s understandable that people want a breakthrough that replaces implants, bridges, or dentures with something biologically natural.

That emotional hook is exactly why misinformation spreads quickly. A short video can imply that a therapy is already “out there,” when in reality the science is still in the careful, stepwise process of clinical validation.

How this connects to today’s real-world options

While we wait for regenerative approaches to mature, modern dentistry already offers excellent solutions for missing teeth and structurally compromised teeth.

If you want a broader overview of tooth replacement and emerging innovation, here’s your 2024 article that covers regrowing teeth concepts alongside modern alternatives:

And if you’re looking at overall health support as part of a “keep your teeth longer” strategy (inflammation, micronutrients, and wellness basics), you can also explore your supplement resource hub here:

What you can do right now (while science catches up)

If you’re hoping to avoid tooth loss in the first place, the highest ROI remains boring — and effective:

  • Consistent home care (brushing + interdental cleaning)
  • Periodontal prevention and early intervention
  • Managing dry mouth, acidity, and frequent snacking patterns
  • Staying current on exams so small problems don’t become big ones

Regenerative dentistry may one day change the landscape. But until then, prevention and early diagnosis still beat any “future miracle.”

Quick FAQ: Can you regrow teeth?

Can you regrow teeth if you lost one as an adult?

Today, no — not as a predictable, widely available clinical treatment. Research is exploring biological regeneration approaches, but they are still in early human trial stages.

Can you regrow teeth with a patch, serum, or supplement?

Be skeptical. Viral products often imply “regrowth,” but typically lack clinical evidence. A true regenerative treatment would require rigorous trials, safety review, and predictable outcomes—not just marketing claims.

Can you regrow teeth in the United States right now?

In routine practice, no. If future access happens, it would be through regulated pathways, typically beginning with formal clinical trials.

Bottom line

Can you regrow teeth? Not as a standard dental service today.

But the USAG-1 research is one of the more credible scientific directions being discussed publicly, and it’s being explored through structured clinical research rather than consumer products and viral hacks.

So, can you regrow teeth today? Not as a routine dental treatment—but the clinical-trial pathway is real, and it’s worth watching carefully.

Dentures: Holding On or Letting Go?

Dentures: Holding On or Letting Go?

by | Jan 10, 2024 | Dentistry, Dentures, Implant, Nutrition, Prevention, Tooth Replacements

I’m willing to bet that many people have a favorite pair of shoes – worn, comfortable, familiar. But what if those shoes start causing more harm than good? The same can be true for dentures, especially when we cling to them long after they’ve overstayed their welcome. In my years as a dentist, I’ve seen countless patients holding onto ill-fitting dentures. Often, the only reason they were I my office at all is that they were brought in by concerned family members who noticed that their dentures looked more like dancing puppets than teeth.

Holding on to dentures for too long is like driving a car with bald tires. You might convince yourself it’s okay, but the risks lurk beneath the surface. Over time, dentures lose their fit as bone recedes, causing instability and potentially painful sores. And let’s not forget the impact on digestion and even your appearance. That sunken profile you’ve gotten used to? A new, properly fitted denture can restore it, sometimes even shaving years off your look.

The American Dental Association recommends a refresh about every five years. That could be a reline or a remake, to keep your dentures in harmony with your changing mouth. Some scoff at that, claiming their ten-year-old choppers are doing just fine. But here’s the secret: small, incremental changes are much easier to swallow than a giant leap many years down the line. When you update regularly, the transition is seamless, like slipping into a well-worn but freshly polished pair of shoes. When you wait fifteen, twenty, or twenty five years before replacing dentures, getting use to the new set can seem impossible.

Implants offer a revolutionary option for some, anchoring dentures like sturdy roots. But not everyone can or wants to go that route. For them, the choice boils down to two paths: hold on to the familiar, wobbly comfort, or take a leap of faith with new dentures.

Today, I wear a different hat. Experience has taught me to read the situation, to gauge whether my efforts will truly benefit the patient. If stubbornness trumps logic, it might be time to let go of the case, especially if it doesn’t appear that any help will be well received. But for those open to rediscovering the joys of proper fit, improved digestion, and a revitalized smile, I am ready to guide them on that journey.

Holding onto old dentures, like those worn-out shoes, can be tempting. But remember, comfort shouldn’t come at the cost of your health and well-being. Talk to your dentist, explore your options, and embrace the possibility of a brighter, healthier smile. After all, sometimes, letting go is the best way to move forward.

The Undercover Culprit: Why Ignoring Open Margins Can Bite You Back

The Undercover Culprit: Why Ignoring Open Margins Can Bite You Back

by | Dec 15, 2023 | Cavities, Cavity, Dental crown, Dentistry, Expenses, Tooth Replacements

Remember that gleaming crown, your loyal guard against the gnashing jaws of fate? Well, beneath its gleaming surface, a cunning villain may be plotting your tooth’s downfall: the insidious open margin.

Imagine this: instead of a tight partnership, your crown and tooth have a tiny gap, a secret handshake reserved for troublemakers. Bacteria, those microscopic mischief-makers, throw a perpetual picnic in this hidden nook, nibbling away at your precious tooth like miniature termites. You might not feel their tiny chompers, no immediate twinges, just the illusion of dental safety. But trust me, the party’s on, and the guest list includes cavities, infections, and even bone loss – all whispering sweet nothings of toothlessness in your ear.

So, why does this silent saboteur slip through the cracks? Several sneaky suspects come to mind:

  • Time’s tiny pickaxes: Years of chomping and grinding can chip away at your tooth, creating tiny crevices where the once-faithful crown no longer fits snugly.
  • Trauma’s unwelcome nudge: A misplaced bite, a rogue popcorn kernel, even a good-natured tumble can nudge your tooth ever so slightly, turning your crown into a loose-fitting disguise.
  • The disappearing glue: Sometimes, the cement anchoring your crown can weaken, allowing it to peek-a-boo with your gum line, leaving a doorway for trouble.
  • The unseen accomplice: And in some cases, the open margin was there from the start, a tiny misstep in the dental dance, undetected and ready to cause mischief.

But here’s the good news: this isn’t a one-way ticket to toothless oblivion. You can shut down the bacteria bash before it turns your pearly whites into a party zone! All you need is a thorough checkup with your dental detective (that’s your dentist!) and a proactive approach.

Remember, ignoring an open margin is like ignoring a leaky roof. You might not see the immediate damage, but the long-term consequences can be a flood of trouble. Replacing the crown, while it might seem like an unnecessary expense, is actually an investment in saving your tooth – and potentially saving yourself thousands down the line.

Think of it this way: a new crown costs a couple of grand. Extraction, bone grafting, and an implant? That’s easily double or triple the price. And let’s not forget the emotional toll of losing a tooth, the impact on your smile, your confidence, your daily life.

So, the next time your dentist mentions an open margin, don’t brush it off as a minor hiccup. Remember, it’s an undercover culprit, a wolf in sheep’s clothing for your dental health. Embrace the proactive approach, get that crown replaced, and send the bacteria packing. Your smile – and your wallet – will sing your praises!

Do Dental Implants Make Financial Sense?

Do Dental Implants Make Financial Sense?

by | Mar 5, 2017 | Bridge, Cavities, Cavity, Dentistry, Dentures, Implant, Periodontal Disease, Tooth Loss, Tooth Replacements

Because tooth-loss so often creates long-lasting and generally negative effects for personal health and, not infrequently, appearance – the entire array of tooth replacement options has long been an important subject in the dental field.  Dentists not infrequently discuss which options are best for their patients, given different circumstances.  And if there is any debate in the profession at all, you can be sure the public will also question which options make the most sense for them.

The truth is there is no one right answer.  Each person’s circumstances differ – whether the reasons are anatomic, functional, emotional, or financial.

But the question is still an important one to ask, because patients face new realities when they lose even one tooth.  These changes include (but are not limited to):

  • Difficulty chewing1677528
  • Altered speech
  • Food impaction
  • Jaw pain
  • Drifting teeth

And, then there are the secondary effects:

  • Poor health resulting from a changing diet
  • Compromised appearance
  • Self-consciousness/embarrassment
  • An inability to wear dentures
  • Financial challenges created by the need to address these problems

It is this last point that I want to touch upon here, because I have observed a good deal of confusion surrounding dental implants.  As a dentist, I am obligated to review all options with an individual when discussing their tooth replacement options – regardless of affordability.  I can’t, and don’t, pre-judge anyone financially when discussing their choices.

Commonly, though, when I raise the subject of dental implants, I get an immediate reaction along the lines: “Oh, forget it. I could never afford that.  How about a bridge?”

1908745

Now, I’m not going to try to convince you that implants are cheap. Restore a full mouth with dental implants and it is likely to be costly.  Nevertheless, cheap is relative.  For some of my patients, even a small filling can be perceived as expensive.  For my wealthy patients, they might be prepared to spend any price for what they perceive will serve them best.  Lucky them.  Right?

What I hope to do here, however, is to show you when an implant may make the most sense for a person. And — at least, when when it comes to replacing a single tooth — a dental implant may just be the way to go.

But first, permit me to remind you again – there is no one right answer for everybody.  Your choices may be very different depending upon whether you are 25 or 85 years old, for example.

I’m sure you can fill-in still other reasons that affect your decision-making process.  But for now, let’s consider the following scenario:

A patient loses one tooth.1478341

For the sake of argument, we’ll call it a lower right first molar.   Suddenly, the patient realizes this is annoying.  Their bite is changing; their gums are sore.  They feel the need to do something.  Now.

Here are a few options. I’m just going to list the main ones, but there are sub-sets to some of these:

  1. Do nothing anyway.
  2. A removable denture.
  3. A non-removable bridge,
  4. A dental implant.

For the purposes of this discussion, the patient has already decided that doing nothing isn’t working for them.

So, the next option is a removable denture.  I usually get “the face” on this one.

1843956

And with good reason.  Food gets caught around partial dentures every time you eat.  You will have to remove the appliance after EVERY meal and clean it separately from your own teeth.  Certain foods will also cause it to dislodge as you eat, allowing some of the food to get caught between the denture and your gums.  The cost – depending upon what kind of partial you have made – will typically range between $750 and $1,500.† The recommended replacement time: every 5 to 7 years.  The reality – people replace them roughly every 15 years.  Sometimes more.  The longer they put off the replacement though, the more issues they may face with the replacement.

Bottom line:  Removable dentures are potentially uncomfortable.  Average lifetime replacement cost if you are 25 years old, (based on an average life expectancy of about 79 years, and an average 10-year replacement rate – not adjusting for inflation) is going to be nearly $7,000.

Next, we’ll take up considering a “bridge.”  It’s called a bridge because it spans a gap (like a bridge spans a body of water) with a fake tooth, or teeth, in between the ones that are still there.  The trouble is that you must shave down the supporting teeth to little stubs so that the result will look natural and be strong enough to take the force of daily chewing.  For the most part, bridges look, and can often feel like, your natural teeth; but you do have to floss under the fake tooth after every meal.  Food will get caught under there, whether you perceive it or not.  If you don’t clean it regularly, the life expectancy of your bridge will be shorter.

Now, the cost on this option can really be widely variable, because some teeth need to have fillings replaced before they can be used as supports for the bridge.  In other cases, the teeth may end up with root canals if the process of shaving them down results in lingering sensitivity.  This doesn’t always happen, but it is a risk.  If the tooth needs that additional treatment it will cost you more.

The average cost to replace a single tooth with a bridge is about $3,500.  Again, that can be a little more, or less, depending upon what part of the country – or even what part of a city, you live in.

If, on the other hand, you also need to place or replace fillings on the teeth being used as supports, and you need to do root canals as well, it could be as much as $7,000.

Roughly, double.1676315

The average lifetime replacement cost with the same parameters given above (25 years old with an average life expectancy of 79 years and a 10-year average replacement rate) is going to be: $31,500.  And that assumes that the underlying teeth will be strong enough to survive that many replacements.

That brings us to dental implants.

Here is the breakdown:  The average implant cost in many metropolitan areas is around $1,800 – $2,200.  If you end up needing a bone graft before the implant can be placed, though, add another $550.  (Basically, a graft is adding bone to your jaw when you don’t have enough for the implant.) So far, these costs are just for the implant.  It doesn’t include the cost of the crown.  Add about another $2,100 for the parts needed to make up what supports the crown above the gumline, and the crown itself.  If your tooth is short, and there isn’t enough tooth height to which your crown can be easily cemented, you might need something called a UCLA abutment — it lets your dentist screw down the crown instead of cementing it.  That could cost you more.  How much depends upon the lab your dentist uses, but $500 more wouldn’t be unusual.

On the low end, one implant may cost $3,900.  On the high end, let’s round up to $4,900.

So, what about the average lifetime cost?

$4,400.

That’s less than either partial dentures or bridges!

Why?

Because, unless you bite into a rock, grind your teeth uncontrollably, or have some serious illness that causes you to lose bone around the implant – any of which can happen to you with the other options as well – you will probably have your implant for life.  Still, no one can guarantee this because, sometimes, plain ol’ dumb luck will factor into any equation.

But, you can’t get a cavity on an implant.  On the other hand, you still can get a cavity on the teeth that support your partial denture, or bridge (and crowns, for that matter).

1678563So, do the math.  Look at your circumstances, and decide what is right for you.  But when your dentist starts talking to you about dental implants, hear them out.  It just might be more cost effective than you realize.

Why You Should Use Common Sense – At Least When It Comes to Oral Health

Why You Should Use Common Sense – At Least When It Comes to Oral Health

by | Aug 2, 2016 | Dentistry, Periodontal Disease, Prevention, Tooth Decay, Tooth Loss, Tooth Replacements

Common sense.  Does it seem to you that this has become a rare commodity nowadays?  Possibly, then, it is really uncommon sense that we should be talking about.

The latest example of an affront to logic – at least for me – lies in the latest media challenge to oral health.  This morning various news agencies including The New York Times, suggested that maybe flossing is really overrated.  Apparently, “officials” have never researched the effectiveness of regular flossing.

Now, millions of people are likely to jump on this as a justification for not flossing.  But, in reality, the new media sensation is probably not going to change very much at the end of the day.  Why?  Because I can confidently tell you – based on more than 25-years of personal experience – most people don’t floss anyway.  About all this latest “research” will promote is the possibility that some people will feel just a little less guilty about what others with any sense (common or uncommon) already understand is a pretty good idea.

But, it makes for good press.  Doesn’t it?1441531

Just for the sake of argument, let’s assume that flossing doesn’t remove plaque.  Heck.  Some people fail to remove plaque with a toothbrush.  That doesn’t mean either fails to benefit the patient, if done properly.  I can think of several reasons why flossing helps, though:

  • Passing floss between the teeth sweeps out the contact point between them – meaning the points where they touch. That’s a source of about 30% of all tooth decay.  Your toothbrush typically doesn’t reach those areas, unless you have gaps between your teeth.  Floss does reach those areas.
  • Flossing stimulates blood flow in the gums. One of the body’s first-line mechanisms of defense is to increase blood flow to an affected area.  You are effectively helping your body do this in a controlled manner by flossing.
  • A number of the bacteria under your gums are anaerobic bacteria. That means they don’t grow in room air. So what is a person introducing into the gum pocket when they pull back their gums by flossing?  Could it be . . . air?  Is it possible that the oxygen in the air could kill some of those bacteria as well?

Think about it.

If we can set aside this newly created question of doubt for just a moment, I would propose that you ask yourself the following question:

“Have I ever flossed consistently?”

By this, I mean every day, and it would have to have included doing so for at least two weeks.

18196564 l

This question is particularly directed to someone if they ever had a gum problem like gingivitis or periodontal disease.  Sure, one needs to get rid of tartar and control bacteria as well, but for patients that make the effort to floss (and with only a few qualifications that I can think of), it is almost a sure bet that their gums got better as a result of the daily exercise. First of all, the gums probably bled less afterward.  Not in the beginning – to be sure – but after about two weeks of flossing every day, we typically see positive change.  Breath improves too. An overall sense of well-being is not out of the question either.

When it comes to flossing sporadically, I agree.  It doesn’t help much.  It’s kind of like exercising once or twice a month.  And let’s face it, that’s where most of the population lives when it comes to flossing — once in a blue moon.  Is regular exercise effective, though?  What does your common sense tell you?

Why would I hold on to this idea in the face of “new evidence”?  Well, I have seen flossing help too many times to just call it a coincidence.  Hard core scientists might say “Oh, well, that’s just anecdotal evidence.  It doesn’t stand up to real scientific scrutiny.”  OK.  Then survey practicing dentists.  Let’s see if I’m the only one with that observation and experience.  I doubt it.

I’m not saying flossing is the only thing you need to do to have healthy gums.  It isn’t.  Diet and good nutrition are paramount.  A healthy immune system doesn’t hurt either.  But for Pete’s sake, flossing is cheap, really not all that hard to do once you have practiced it for a while, and it can end up saving you a lot of money in the long run.  With health care costs being what they are, I can’t think of too many actions a person can take that bear as much fruit and keep money in their pockets.

But, if the media has just succeeded in making you feel better about not flossing, then OK. Bully for them. (Heaven knows, they do a top notch job spending most of their time getting people to feel less than great.)

And, I suppose there are other ways to handle tooth loss – which, by the way, happens a lot more from gum disease than tooth decay.

How Long Do Dental Crowns And Bridges Last?

How Long Do Dental Crowns And Bridges Last?

by | Dec 2, 2015 | Bridge, Dentistry, Prevention, Tooth Replacements

How long do dental crowns and bridges last? 

I haven’t written anything to the blog for some time now.  Like so many people I know, I have been busy with other projects.  Every now and then, though, something will come up and I find I tell myself, “I need to write about that”.   Recently, an exchange with a patient prompted me to write on the subject of how much time a patient might expect from a crown or a bridge. 

What I found interesting was this patient’s viewpoint about something that was happening with her relative. It seems that this relative was experiencing a problem that required she/he have a crown re-made.  My patient, made an off-hand comment to me along the lines that her relative’s dentist might not have been so great because the crown was having to be redone.   

I’m thinking: Oh, it must have just been placed recently. 

She’s thinking:  After about twenty years. 

Granted.  My patient has not (yet) had to replace any of her dental work and she has been with me nearly twenty-five years.   

But here’s the thing: as a dentist when I hear that a crown lasted twenty years, I think – “Sounds like that dentist did a pretty good job.”  It seemed to me, my patient had an entirely different impression. 

I asked her: “Did you realize that the average life for a crown or bridge is only between 5 and 15 years?”  My patient seemed a little alarmed by that, but acknowledged she did not realize it. 

There are so many factors that can go into how long a crown or bridge may last, that this can be really difficult to predict.  The five- to fifteen-year figure often cited by dentists is based upon university studies and insurance company estimates of how frequently they need to be replaced.  Most insurance companies will pay for a new crown after five years, although, a number of them have recently extended that replacement date to 7 or even 8 years.  

In all fairness, sometimes crowns can fail due to manufacturing errors.  But the reality is that this is very seldom the case.  More often it is the patient that fails the crown.   

How so?  There are two main reasons:  decay under a poorly maintained crown and tooth clenching and grinding. 

But here are a few other ways a crown can break – 

  • Removing bottle caps 
  • Biting fingernails 
  • Cracking crab claws 
  • Holding roofing nails 
  • Tearing open cellophane packages 

Inappropriate use can cause porcelain that is veneered onto a metal base to break off.  Using common sense is important.   

 

Provided a crown is manufactured to high standards, after choosing the right material for you, and having it fitted correctly to your bite it has the potential to last a lifetime. 

 

Home care has something to do with it too. 

In my twenty-five years of practice, I have seen this repeatedly.  For me, two cases have illustrated it best: 

Earlier in my career, I had a patient who needed a lot of dental work.  He already had a lot done, but much of it was pretty old and, frankly, it didn’t look very good.  It’s actually uncommon for me to see work that I believe wasn’t done carefully, but if any situation fit that bill, this was it.  His crowns fit like “socks on a goose.”  I don’t know where he had it done and, at this point, it really isn’t the moral of this story.  The important thing is that this work was, apparently, what he could afford at the time.  What amazed me was that these crowns were still functioning after more than twenty years.  There was no reason they should have.  They fit that badly. So, why were they working?  This patient’s home care was excellent.  He brushed and flossed after every meal.  He knew that getting new dental work was going to be costly for him, so Mr. Flosser he made sure that what he had lasted him.  I was impressed. 

 

Not too many years thereafter, I saw a different patient for a new patient exam. This man had bridgework from ear to ear.  Honestly, it looked great.  Pretty much everything about his crown and bridge work was technically correct.  The bite was good, they were esthetic, and when I took his diagnostic x-rays, I noticed that the critical areas fit perfectly.  Someone obviously took a great deal of care to make sure that they delivered a great product to this patient.  I would have gone to that dentist. 

 

But another thing that I observed when I reviewed the films was that there was decay all over the place.  So much, in fact, that the only way to correct it would have been to remove the bridges, clean out the decay and replace everything. 

 

The likelihood that his dentist would have left behind that much decay is nearly zero.  No one who took that much care into crafting his work would have allowed it.  But the real reason I know that is this:  during the course of my exam, I observed that this patient has so much plaque and garbage in his mouth, I doubt he ever brushed his teeth.  It looked like he had just finished eating cottage cheese before he came in.  The plaque was that heavy. 

 

This man’s dental work was only between two and three years old. He probably paid a small fortune for it.  It was that extensive. 

 

Now, I had the unpleasant task of telling him my findings.  To make a long story short, I never saw him again.  Mr. Cottage Cheese probably thought I was trying to put one over on him.  Nothing bothered him (yet!), and it was most likely inconceivable to him that he should have anything wrong in so short a time.  And yet, it was not a promising scenario. 

 

Today, however, an equally common cause of crown or bridge failure is tooth clenching and grinding.  I have written about this epidemic elsewhere.  But, if you grind or clench your teeth, things are just going to wear out a lot faster.  It’s just common sense.  If you had a choice of parking your car in the middle of a golf driving range or outside of the driving range, under which conditions is your car likely to end up with the better paint job? 

 

Some people can place amazing forces on their teeth.  When they do, if a tooth was in really bad shape before it was restored, the crown probably won’t survive the weak tooth.  You need something of a substrate to support and retain the crown.  The cement can’t be relied upon to do the entire job.   

 

Also, to put things into perspective, the average force on a back tooth is typically around 75 pounds per square inch.  When we chew, that goes up a little – maybe, to 80 or 90 pounds per square inch.  Remarkably, some people have been recorded as having applied as much as 3,000 pounds per square inch on their teeth while sleeping. That can crack a virgin tooth, let alone one that has had any work done to it. 

 

In the end, there really isn’t a simple answer as to how long a crown should last. It can vary.  With all other factors being equal, I would hope for no less than seven years and consider anything beyond fifteen years “good.”   

 

Many of my patients who are still with the practice after 25 years and that I still have the opportunity to examine, continue to have their original crown and bridge-work.  But some have moved to other states, and others have passed away in their older years.  Yet, much of what I can see looks pretty good.  Some old crowns and bridges could use a face-lift. That usually means replacing it. 

 

Every now and then, I wonder about those two patients I mentioned above:  Mr. Flosser and Mr. Cottage Cheese. 

 

Mr. Flosser may still be running around with those old crowns. 

Mr. Cottage Cheese is probably wearing dentures by now. . . .

Full Dentures – Problems and Solutions

Full Dentures – Problems and Solutions

by | May 18, 2015 | Communication, Dentures, Medical Issues, Nutrition, Tooth Loss, Tooth Replacements

Millions of people worldwide wear full dentures.  While we often associate this aging, wearing full dentures is not just limited to older adults.  Illness, accidents — sometimes even pregnancy — can contribute to tooth loss and, in a number of cases, this affects younger individuals as well.

Young or old, the psychological consequences of losing teeth can be severe.

Several studies have suggested that a smile is very often the first thing people notice about another person.  So, losing one’s teeth can be devastating in a variety of ways.

Toothlessness may affect digestion. This, in turn, can influence nutrition and health.   There can be issues with self-esteem, intimacy, and a host of other areas most people wouldn’t normally take the time to consider.

This is stressful enough.  But having to now replace the teeth can also become stressful for some.

Many people worry about whether they will be able to eat with their dentures.  Will people notice that they are wearing them?  Will they sound funny when they speak?  Will it hurt to eat with the dentures? Will they be able to chew their food?  How will the dentures affect the ability to taste food? Will the dentures slip when they talk?  What can they afford?

These are natural concerns, but for the first-time wearer, they add up to a lot of unknowns.

The truth is that no two situations are alike. But almost all denture challenges have solutions.

Another thing to consider is that there are many ways to go about addressing total tooth loss.  The solutions depend upon a person’s preferences, financial options, and — frankly — anatomy.

If a person were building a house and they decided to hire an architect, the architect would undoubtedly first gather a lot of information about the project.  For example:  Where is he going to be building? What does the client want: a log cabin or a mansion?  What does the foundation look like?  What is the client’s budget?

In some ways, restoring a person’s smile is not too dissimilar.

For the person without teeth, they may be surprised to learn that there are multiple ways to go about replacing the teeth.  The length of time will vary with each approach, as well as the cost.

To help clarify the options and give some sense of the costs, I put together a free report that helps discusses different levels of care, from simple to more complex. Included is a sense of the pros and cons of each approach, and a general price range at today’s rates.  Of course, this can vary widely from area to area and doctor to doctor.
