Periodontics is a specialized branch of dentistry that focuses on the prevention, diagnosis, and treatment of periodontal disease as well as the process of replacing teeth with dental implants. Periodontists receive up to three years of additional, specialized training in treating periodontal disease and other conditions.

Periodontists are also specialists in treating oral inflammation and any condition requiring either non-surgical treatment or oral plastic surgery. Oftentimes, periodontists are treating conditions caused by periodontal disease and its effects such as persistent bad breath or gum recession.
