Sounds like a pretty basic question for a dentist, doesn’t it? In fact, I’m not really asked that question often because “everybody knows” you should brush your teeth twice a day. But should you really?
After all, you can pick up almost any tube of toothpaste and it says right there” brush twice daily, or as directed by your dentist”.
Some time ago, I started asking patients how often they brushed their teeth when they came in for their periodic cleanings. The most common answer – by far – is “twice a day.” My next question is usually, “Yes, but when during the day do you brush?” As you read this, many of you who do brush twice daily are thinking “when I get up and again before I go to bed.”
If you have experienced dental cavities, that could be part of the problem.
When I mention this to patients I usually get this sort of silent stare. It’s kind of a cross between, “well that makes no sense at all” or, “then I might as well just give up.”
Let me explain.
It starts with an understanding of what causes dental cavities. There are a few basic elements. The most obvious is that you need to have a tooth. Additionally, you need cavity-causing bacteria. Then you also need a fermentable carbohydrate. This is an important point. Carbohydrates include sugars and starches, but the process of fermentation creates acids. Once the acids form, there is another element that comes into play: time.
If we break these factors down further, it is useful to look at what we can control in the cavity-causing process. For the sake of argument, let’s assume we are starting out with a full set of teeth, so that’s not entirely in our control. Next, there is the factor of cavity-causing bacteria. We all have both good and bad bacteria in our mouths. While I could get into a discussion of promoting the good and suppressing the bad, this is also not always easily controlled.
The next two factors, however, we have a great deal of control over.
We can control what we eat. Recognition of which foods are acid forming is also useful. But I’m a realist and understand that sometimes we are just going to eat (or drink) those things anyway.
And this is where the time factor comes in.
A little analogy may be helpful here. What would you do if you spilled a strong acid on your bare skin? Chances are you would run right over to the nearest sink and try to wash it off. But what if you had a leather jacket on and didn’t notice right away? First of all, you would end up with a hole in your jacket, but eventually – with time – it would reach your skin and start to hurt.
It’s much the same with teeth. Your enamel is a protective layer that doesn’t have any feeling because it is mostly mineral and doesn’t contain any nerves. But given enough time, the acid – even a weak one – breaks through and gets to the underlying softer and more sensitive areas. So, don’t give it time.
Change your brushing habits and do so after every meal. About a half hour after eating is ideal. If you absolutely can’t brush on occasion, chewing a sugarless gum (preferably containing xylitol) can help.
What most people do, though, is wake up and brush. Then they have breakfast and don’t brush. The acids that are formed following the meal slowly dissolve our tooth enamel. Roughly when the acids wear off, they have another meal or a snack and freshen up the acid. Few people brush after lunch, so it’s a few more hours of wearing the enamel away. Just when that acid wears off people freshen it up again with dinner. They don’t always brush after dinner either, so the acid now has even more time to work. Finally, they brush before going to bed. This cycle can, and typically does, go on for days, weeks, months and years. Given enough time, the cavity becomes large enough to require a filling.
So, if you only eat two meals a day, brushing twice a day is probably fine. But if you eat three times a day, how often should you brush? You get the idea.
The really odd thing is that I can go over this with someone thinking they get it. A couple of years later, I’ll ask: “How often do you brush your teeth?” Believe it or not, the answer is often the same as when I asked the first time. Hopefully, however, you will get it. Remember also that you can’t ignore flossing and expect to escape cavities, even if you do brush after every meal. The area between your teeth can’t be reached by the toothbrush bristles. About a third of all cavities filled by dentists occur in this location.
Nevertheless, if you follow the advice above I think you will find yourself encountering far less tooth decay over the years. Hoping it works for you as well as it has for me.
I have been practicing dentistry for just over twenty years. In that time, I have had strangers, friends and family ask me questions about their dental problems. Maybe this question is one that has come up for you too. One of the more frequent queries I run across goes something like this:
“I recently went to the dentist and I was told I needed to have a filling done. It didn’t bother me before, but it does now – and what’s more, I’m being told I’ll probably need a root canal! Did I mention the tooth wasn’t bothering me? But now I’m looking at over $2,000 in dental bills, because once I’m done with the root canal I’ll have to put a crown on the tooth!”
Are you thinking, hmmm, that darned dentist probably should have just left the tooth alone?
Yeah, that’s usually what they are thinking too.
One of the first questions I then ask is: “Was there already a large filling on the tooth?” Invariably, the answer has been “yes.” In which case, my response is usually “Well, then, it’s really not that unusual.”
The first thing to understand is that the tooth was already treated before. The fact that it already has a large filling, suggests that either the original decay was extensive or it had to be replaced several times. Depending upon the location in the mouth, and severity of pressure placed upon the teeth, fillings do require replacement. Teeth are also not immune to new decay and larger fillings do not typically last as long as smaller ones.
So, picture a filling that originally came close to the nerve. Now, there is either new decay between the old filling and the remaining tooth structure – putting it even closer to the nerve – or there may be a fracture occurring between the tooth and filling because there is not enough enamel left to support the filling. Either way, the nerve is under assault.
The next comment is usually “Well, since it wasn’t bothering me, shouldn’t he have just left it alone?” Trust me, this is not a favorite situation for your dentist either. If he leaves it alone, the likelihood of it turning into a root canal is higher. Then the question becomes “why didn’t he tell me about it sooner?” And if it doesn’t turn into a root canal the patient risks losing the tooth if it fractures. So, really, the tooth’s chances of remaining calm are better if it is treated sooner.
Probably the biggest problem here is the omitted communication. Most of the time, the patient simply wasn’t told there would be a risk of post-operative sensitivity. While the dentist can’t entirely control whether the tooth will recover from a deep cavity or not, it helps when the patient knows there is a chance of later discomfort. The moral of the story: don’t put off your dental treatment. Small cavities conserve more tooth structure and seldom bother you afterwards. Large or deep feelings always put the tooth at risk of more treatment or greater discomfort.
Probably one of the most common dental misconceptions revolves around the idea that in order for a tooth to have a problem it has to hurt. Certainly, if a tooth is aching, we can agree that there is most definitely something wrong. But can a tooth have a cavity and not hurt you? If so, should this still be a cause for concern?

A simple fact: your smile is among your most important physical attributes. The effect of a sparkling confident smile on personal, social, and business relationships has been proven to be crucial.
But many of us are not confident in the power or sparkle of our smiles. We worry that our teeth may be discolored. We may be self-conscious about a small chip in a front tooth. We might be concerned that old, ugly fillings become visible if we make a huge happy grin.
And, let’s face it – not all of us are born with beautiful and bright teeth.
Today, great new strides in modern dentistry can help you convert that smile so that it can be a dazzling part of your personality.
We have the technology that can give you a confident and beautiful smile.
Tooth whitening is an easy, affordable, and painless way to brighten teeth discolored from food, nicotine stains, or root canal treatments, or that have become darkened with age. Worn down, chipped, cracked or widely spaced teeth can be repaired through a process known as bonding, where a tooth-colored plastic is applied to your teeth and cured with a light. The result looks and feels like the original.
Severely stained or chipped teeth may require veneers, ultra-thin sculpted pieces of tooth-colored porcelain that fit over the front of your teeth.
If your teeth have undergone root canal treatments, are misaligned, or weak, then crowns may be the solution. Crowns can also help you to look fantastic, and provide great strength since they entirely cover the affected tooth.
We have all the technology that can give you a confident, beautiful smile. We’re here to make sure you look and feel your powerful best!
