Adult Tooth Decay
The Cause
A healthy mouth contains natural, good bacteria that neutralize acids and help clean up food particles. This bacteria and your saliva also help strengthen areas of demineralization on teeth by restoring the minerals that protect teeth from decay.
Sometimes harmful bacterial plaque can throw a healthy mouth’s homeostasis into chaos. Plaque is a sticky bacterial substance that can build up on your teeth. Harmful bacteria in plaque secrete an acid that destroys tooth enamel to create cavities. This acid demineralizes the tooth enamel, and if it reaches the dentin, can cause pain where nerves and blood vessels are vulnerable. Often a cavity that grows to affect the dentin must undergo a root canal or extraction. In short, tooth decay can destroy teeth.
