Treatment of periodontitis (PERIODONTOLOGY) is a field of dentistry that deals with the prevention and treatment of periodontal disease as well as oral mucosa diseases. The periodontium is a set of tissues that surround and immobilize the tooth. In addition, it is designed to protect teeth against the ingress of infection from an infected gingival pocket or root canal. Periodontosis is the colloquial name for periodontitis. It is a chronic disease in which bacteria attack our gums, which can lead to serious changes in the teeth. This is a disease in which periodontal tissues are infected, which in turn leads to inflammation. As a result of inflammation, the tissues that support the teeth are destroyed. The result is a weakening of the tooth, and in the worst case - its loss.
