Dental caries is a term used for tooth decay or cavities. It is caused by specific types of bacteria. They produce acid that destroys the tooth’s enamel and the layer under it, the dentin. Many different types of bacteria normally live in the human mouth. They build up on the teeth in a sticky film called plaque. This plaque also contains saliva, bits of food and other natural substances. It forms most easily in certain places. These include:
- Cracks, pits or grooves in the back teeth
-
Between teeth
- Around dental fillings or bridgework
- Near the gum line
Early
caries may not have any symptoms. Later, when the decay has eaten
through the enamel, the teeth may be sensitive to sweet, hot or cold
foods or drinks.
Caries caught in the very early stages can be reversed. White spots may indicate early caries that has not yet eroded through the enamel. Early caries may be reversed if acid damage is stopped and the tooth is given a chance to repair itself naturally. Caries that has destroyed enamel cannot be reversed. Most caries will continue to get worse and go deeper. With time, the tooth may decay down to the root. How long this takes will vary from person to person. Caries can erode to a painful level within months or years.
One
way you can prevent cavities is by reducing the amount of plaque and
bacteria in your mouth. The best way to do this is by brushing and
flossing daily. You can reduce the amount of tooth-damaging acid in your mouth by eating sugary or starchy foods less often during the day.
