Periodontics is the prevention, diagnosis, and treatment of periodontal disease or gum disease, and the placement of dental implants. This may include gum recession and oral pathology like gingival tumors. A dentist who specializes in this is called a periodontist. Many periodontists can also help patients replace teeth lost due to periodontal disease by placing dental implants.
Periodontists are experts in treating inflammation inside the mouth. They receive extensive training in these areas, including three additional years of education beyond dental school. They are very familiar with the latest techniques for diagnosing and treating periodontal disease, and are also trained in performing cosmetic periodontal procedures.
