Itchy gums are a sign of inflammation of the gums. Gingivitis is a common periodontal disease, caused by inflammation formed by irritants around the teeth that irritate the gums. If you develop in gingivitis, you can go to the hospital to have your teeth scaled. Remove plaque and calculus around the teeth by ultrasonic shock, then rinse locally with 3% hydrogen peroxide, then apply iodine glycerin or Paregoric ointment to the gums to reduce inflammation, and then rinse with mouthwash. Commonly used mouthwashes include chlorhexidine solution, rehabilitative new solution and tinidazole solution, etc. The use of mouthwash can consolidate the effect of scaling, maintain the flora environment in the mouth and keep the oral hygiene. This will allow the gingivitis to heal and not progress further. If gingivitis is not controlled in a timely manner, then part of it will continue to destroy periodontal tissues and form periodontitis. If the gum inflammation is caused by periodontitis, not only will the teeth need to be scaled but also subgingival scraping will be done. So for periodontal disease must be diagnosed early, early treatment, in the early stage to control it, so that it does not continue to develop, will not form the more serious consequences of the late.
