A periodontist is a dental specialist who focuses on the prevention, diagnosis, and treatment of diseases and conditions affecting the gums and supporting structures of the teeth. They specialize in managing periodontal diseases such as gingivitis and periodontitis, as well as performing procedures like scaling and root planing, gum grafting, and dental implant placement. Periodontists work closely with general dentists and other specialists to provide comprehensive oral care and maintain the health and functionality of the gums and teeth. Their expertise ensures optimal oral health and helps prevent tooth loss due to periodontal problems.
