The purpose of periodontology is to treat gum disease and the tooth’s support tissues responsible for bleeding, dental mobility, halitosis, inflammation, and bone loss. It requires the use of medical and if necessary surgical protocols. The health of the periodontium is a prerequisite for the durability of natural teeth as well as restored teeth or implants. The prevention and / or early treatment of periodontal diseases is undoubtedly a better prognosis than late treatment. The diseases of the gums have a significant impact on the general health (diabetes, cardiovascular diseases, fat ...). The main goal of periodontal therapy is the preservation of teeth.
