Periodontal disease is the most common type of oral disease. It can also cause great harm to oral health, with symptoms such as bleeding gums, tooth pain, weak bite, and even tooth loss. For the treatment of periodontal disease, it is recommended to remove plaque, tartar and other irritants from the mouth to eliminate inflammation, as well as medication and, in severe cases, surgery for periodontal disease. Periodontal disease is usually due to the inflammatory reaction of bacteria in plaque and its metabolites stimulating the gums, redness, swelling, easy bleeding and other symptoms, if not treated in time, part of the inflammation will continue to develop, resulting in periodontal abscess, loose teeth or even loss. Dentists usually doctors will thoroughly remove the infected irritants around the teeth through treatments such as scaling, scraping and root planing to control the further development of periodontal disease, relieve the symptoms and maintain the healthy condition of the gums. In severe cases of periodontal disease that cannot be controlled by the above treatments, systematic periodontal surgery is required to control the local infection and restore the health of periodontal tissues. While undergoing treatment, it is recommended to do a good review, strengthen the care of the oral cavity in daily life, do regular oral examination, as well as strengthen physical exercise, improve resistance, and pay attention to diet and nutrition.
