Cavity
Also called tooth decay, caries
A hole in a tooth caused by decay, which grows if left untreated.
A cavity is damage to a tooth caused by acid from bacteria that feed on sugars and starches. It starts in the enamel and can move deeper to the dentin and pulp if untreated. Early decay can sometimes be stopped with fluoride, while larger cavities need fillings. Prevention includes brushing with fluoride toothpaste, limiting sugar, sealants and regular visits. Dentists call decay caries, so you will see that word in notes and claims.
Example at the front desk
The X-ray shows a cavity between two molars, so I scheduled a filling.
