During the course of their lives, three out of four people will suffer from some form of periodontal or gum disease.

In fact, it’s so common that it’s the leading cause of 70% of adult tooth loss. Periodontists can perform a comprehensive examination of your gums and provide treatment to help prevent, reverse, or offset the damaging effects of this disease.
