A periodontist is a dentist who specializes in the prevention, diagnosis, and treatment of diseases affecting the gums and the bones that support your teeth.

They commonly treat:

• Gum disease, including gingivitis and periodontitis
• Receding gums
• Bone loss around teeth
• Gum infections
• Loose teeth caused by gum disease
• Dental implants and the surrounding tissues

A periodontist usually receives several additional years of specialized training after dental school.
