Why Cavities Don’t Hurt Until It’s Too Late

Why Cavities Don’t Hurt Until It’s Too Late

It’s a scenario many of us have experienced: You visit the dentist for a routine check-up, expecting a clean bill of dental health, only to be told you have a cavity. But wait, you think, I didn’t even feel anything! How could this be?

The truth is, cavities often don’t cause pain until they’ve progressed to a point where significant damage has been done to the tooth. This phenomenon can be attributed to the structure of our teeth and the nature of tooth decay itself.

In the early stages of tooth decay, which typically begins in the enamel—the outer layer of the tooth—there is seldom any pain. This is because enamel is primarily composed of minerals and contains very few nerve endings. As a result, when decay is limited to the enamel, there are no nerves present to signal pain.

However, as decay progresses and reaches the deeper layers of the tooth, such as the dentin or pulp, where nerve endings are more abundant, pain may develop. By this point, significant damage has likely occurred, and the decay may have advanced to a stage where a root canal or extraction is necessary.

This delayed onset of pain can lead to a false sense of security for patients, who may delay seeking dental treatment until symptoms become unbearable. Unfortunately, by the time pain develops, the decay may have already caused irreversible damage to the tooth.

In many cases, dentists aim to intervene at the earliest signs of decay, typically opting for conservative treatments such as fillings, inlays, onlays, or crowns to restore the tooth’s structure and prevent further damage. These treatments are often successful in halting the progression of decay and preserving the tooth’s function.

However, there are instances where decay may be more extensive, and the decision to attempt restoration without a root canal may still be made. This decision is based on several factors, including the extent of decay, the condition of the tooth, and the patient’s overall oral health. While the goal is to preserve the natural tooth whenever possible, there are cases where restoration without a root canal may not be successful, leading to the need for additional treatment down the line.

Unfortunately, some patients may perceive the decision to attempt restoration without a root canal as inadequate care, especially if they experience pain or discomfort following the procedure. If the restoration doesn’t produce pain, this perception typically doesn’t arise in the patient’s mind. It’s important to understand that dentists carefully weigh the risks and benefits of each treatment option and make decisions based on what they believe is best for the patient’s long-term oral health.

By understanding why cavities don’t typically hurt until it’s too late and the factors involved in treatment decisions, patients can make informed choices about their dental care and work collaboratively with their dentist to achieve optimal outcomes. Prevention, early intervention, and open communication are key to maintaining a healthy smile for life.

When was the last time you had a dental exam?

Many people believe that since they aren’t experiencing dental symptoms – like tooth pain or bleeding gums – then all must be well.

Unfortunately, a sizable number of dental problems, including cavities and periodontal disease (bone loss around your teeth), just don’t produce obvious symptoms in their early stages.  At least not symptoms that tend to be obvious to patients.

In fact, by the time people the average person experiences pain, his dental issue is typically pretty far along.  And all too often, by then, the problem can also be quite expensive to handle.

It might amaze you to discover the types of problems your average dentist encounters every week, many of which you would expect to be painful, but they just aren’t.  They can still result in tooth loss though.

Pretty much anyone who has ever worked in a dental office for any length of time will tell you this is so.  And they will tell you that you can inform some people that they have a problem, but unless it is “real” to them, they just won’t do anything about it.

They may come back a few years later (or maybe sooner) – usually with an emergency – desperately wanting to save the tooth that you told them about earlier.  Of course, by now, it may be too late.  And very often they will have forgotten it was ever discussed at all, because it was never a realistic problem for them to begin with.

Human nature can be funny that way.

So, keeping that in mind, it’s generally a good idea to get checked out by a dentist.  Regularly.

The best news you can hear is that everything looks great.

But sometimes getting a confirmation that you don’t have cavities or gum disease is not the only reason to get a dental exam.  Over the years, I have detected cancer (not just oral cancer) – as well as a host of other non-dental problems – that might have been overlooked had the patient not scheduled an exam.  Obviously, we refer patients to an appropriate specialist for treatment when we discover medical problems outside the scope of dental practice.

Other benefits of getting a dental exam:  I can recall many patients who told me that what they thought were unrelated health problems simply resolved when their oral problems were gotten under control.  These have included digestive problems, low energy problems, elevated blood cell counts, hypertension, and more.

Over the years, some people have told me they don’t want to get a dental exam because they don’t want to discover they have any problems.   I guess that works.

Just maybe not too well.

Do Dental Implants Make Financial Sense?

Do Dental Implants Make Financial Sense?

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 chewing
  • 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?”

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.

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.

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.

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).

So, 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?

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.

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?

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. . . .
