Under normal circumstances, patients with periodontitis should seek treatment at the periodontics department of a formal hospital. Professional periodontists will perform periodontal cleaning, scaling, root planing, periodontal flap surgery, etc. on the teeth. These periodontal treatment methods can effectively remove a series of infectious substances such as tartar, plaque, and soft deposits adhered to the teeth, thereby achieving the purpose of curing periodontitis. Additionally, periodontitis requires long-term, continuous treatment. It is essential to follow the doctor's advice, revisit regularly, and have teeth cleaned every six months or annually to maintain the current condition of the periodontium and prevent further inflammation.
