Tooth decay is not just a problem for children. It can happen as long as you have natural teeth. Dental plaque – a sticky film of bacteria — can build up on teeth. Plaque produces acids that, over time, eat away at the tooth’s hard outer surface and create a cavity.
Tooth decay, gum disease, chronic dry mouth, and oral cancer can occur at any age.
