A cavity, or dental caries, is a small hole that forms in your tooth. This happens when bacteria in your mouth produce acids that eat away at the enamel, which is the hard outer protective layer of your teeth. Unfortunately, once the enamel is gone, it can't grow back, meaning cavities cause lasting damage to your teeth. If you think you might have cavities or want to check your dental health, please make an appointment by calling (415) 282-8462.
