Not only is tooth decay the most common and widespread disease of humankind, it is possibly the oldest. Skulls of pre-historic humans have been examined and tooth decay has been found.
The latest findings from the U.S. Centers for Disease Control and Prevention’s National Center for Health Statistics show that more than 25% of American adults ages 20 to 64 have untreated tooth decay, and 91% have one tooth — or more — that has been treated for tooth decay or needs to be.
While tooth decay and complete tooth loss have dropped among Americans since the 1960s, disparities still remain, and there’s room for improvement in our oral health.
