While fluoridated drinking water has helped ensure that people under age 50 have an excellent chance of keeping all their teeth, older individuals may not be so fortunate. In fact, the Centers for Disease Control and Prevention reports that one-quarter of American adults over the age of 65 have lost all their teeth; the National Institute of Dental and Craniofacial Research indicates that 58% of Americans over age 50 have fewer than 21 of the normal 32 teeth. Missing teeth lead to poor nutrition as well as a possible collapse of the vertical dimension of the lower face. To avert these potential problems, dental implants provide the best functioning, and most natural-looking, replacements.
P.S. Dental implants are rooted inside the jawbone, which prevents the bone resorption that causes the bone underlying lost teeth to shrink.
