Among adolescents ages 12 to 19, more than half (57%) have had cavities in their permanent teeth. Among adults aged 20 and older, about 90% have had at least one cavity. By the time they reach age 65, 96 percent of Americans have tooth decay, according to the survey. The infectious disease known as dental caries affects 97% of human beings.
By reducing the pH level in the mouth, bacteria demineralize the teeth and erode enamel protection. But for some lucky people, the nutrients found in saliva can remineralize teeth to stop cavities. Virtually all American adults have cavities and more than a quarter have cavities that haven't been treated, according to a new government survey. 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.
