Periodontitis is a disease of the periodontal tissue that surrounds the teeth. This includes soft tissue (the periodontal ligament and gum) and hard tissue (the root cementum and alveolar process).
The stability of each tooth in the alveolar arch depends on these tissues. Periodontics is the branch of dentistry that treats periodontitis and other problems or diseases of the periodontium.The most common interventions are the conservative treatment of periodontal pockets, periodontal surgery and regeneration, covering receding gums (with or without connective tissue grafts) and periodontal surgery using laser technology.
