Periodontal therapy involves a variety of treatments, such as scaling and root planing, periodontal surgery, and laser therapy. These treatments can effectively remove plaque and bacteria from your teeth and gums, reduce inflammation and infection, and promote healing. The first phase of periodontology scaling and root planing is cleaning the root surfaces to remove dirt. Moreover, the smoothing of the root surface prevents recurring buildup and allows for the repositioning of the gingiva (gum tissue).
