Tooth Decay
Why get sealants?
The most important reason for getting sealants is to avoid tooth decay.
Fluoride in toothpaste and in drinking water protects the smooth surfaces of teeth but back teeth need extra protection. Sealants cover the chewing surfaces of the back teeth and keep out germs and food.
Having sealants put on teeth before they decay will also save time and money in the long run by avoiding fillings, crowns, or caps used to fix decayed teeth.
What causes tooth decay?
Germs in the mouth use the sugar in food to make acids. Over time, the acids can make a cavity in the tooth.
Of course a healthy tooth is the best tooth. So it is important to prevent decay. That's why sealants are so important.
Why do back teeth decay so easily?
The chewing surfaces of back teeth are rough and uneven because they have small pits and grooves. Food and germs can get stuck in the pits and grooves and stay there a long time because toothbrush bristles cannot brush them away.
Besides sealants, are there other ways to prevent tooth decay?
