Tooth Decay Risk & Prevention
Tooth decay is often the second most prevalent human disease, after the common cold. Without effective treatment it can lead to pain, tooth loss, and sometimes worse illnesses. Today it is estimated that over a quarter of U.S children from ages two to five, and half of those aged 12-15, have tooth decay. But it doesn't necessarily have to be like that! You can take steps to prevent tooth decay from harming your teeth — or those of your loved ones.
If you've been in the dental office for routine visits, you're already familiar with the special tools dentists use to remove buildups of plaque (a bacterial biofilm) and tartar (a hardened deposit, also called calculus) from your teeth. Hand-held instruments, ultrasonic scalers, or both may be used to give your teeth a thorough cleaning. Afterwards, your teeth are thoroughly checked for decay, and cavities are treated when necessary.
Yet there's still more that can be done to prevent tooth decay. Could your diet be a contributing factor? Is your brushing technique adequate? Could you benefit from additional preventive treatments? Today, with our increased understanding of what causes tooth decay and how to treat it, it is possible to focus on what decay prevention tactics would work best in your particular case. In fact, it's now possible to assess each individual's risk factors for decay, and concentrate on doing what's most effective for you.
How Does Decay Start?
It's useful to think of the mouth as a dynamically balanced ecosystem, in which living organisms, including helpful and harmful bacteria, are constantly interacting. When conditions are right — namely, in the presence of certain sugars — some pathogenic (harmful) bacteria produce acids that cause teeth to lose minerals and begin breaking down. Even a diet having excessive acidic foods can influence deminerialization of your teeth. But in more favorable conditions, the damage these pathogens do is undone by the body's own healing mechanisms — which includes your healthy saliva.
Keeping up a regular habit of brushing and flossing, getting adequate fluoride, and a diet with limited acidic foods is certainly helpful. Yet even with these measures, some individuals will be more prone to tooth decay than others, and may need extra help and guidance.
Additional Steps to Prevent Tooth Decay
If you're one of these individuals, it may help you to learn effective brushing techniques and practice other measures at home — for example, using special electronic toothbrushes that help reach areas manual toothbrushes don’t .
When necessary, in-office treatments such as topical fluoride applications are available. If you aren't getting enough fluoride through drinking water or other sources, this treatment can help prevent tooth decay.
Finally, if yours or your child's teeth are susceptible to tooth decay, consider having a dental sealant applied. This is a practically invisible layer of plastic resin that is placed on the top (chewing) surfaces of the back teeth. It's a painless procedure that fills in the natural pits and folds of the tooth, making them much more resistant to bacterial damage.
So, don't think that tooth decay is inevitable — instead, find out what you can do to help prevent this disease from affecting you or your loved ones.
