Periodontics is that specialty of dentistry which encompasses the prevention, diagnosis and treatment of diseases of the supporting and surrounding tissues of the teeth or their substitutes and the maintenance of the health, function and esthetics of these structures and tissues.

A periodontist is a dental specialist that has not only completed 4 years of dental school, but has also completed an additional 3 years of specialty training in diagnosing, preventing and treating gum disease. Periodontists can also place dental implants as well as perform cosmetic periodontal treatments.

A periodontal evaluation is sometimes the only way to detect gum disease.
