How many cavities does an average person get?

Adults between the ages of 20 and 64 show significant signs of tooth decay. One in four adults will have at least one cavity. Adults in this demographic group have an average of more than 3 missing or decayed teeth and more than 13 decayed or missing tooth surfaces. Cavities in children's permanent teeth or cavities in young children who still have years left before their permanent teeth come out are usually treated with direct fillings.

Virtually all American adults have cavities and more than a quarter have cavities that haven't been treated, according to a new government survey. Despite how prevalent and preventable tooth decay is, many people do not implement good dental hygiene practices that can deter tooth decay from forming. However, since it's so difficult to detect cavities on your own, it's important that you have a dental exam every six months so that we can check for cavities in your mouth.
