Periodontal scaling is really useful for periodontitis

Periodontal scaling is really useful for periodontitis. Periodontitis is primarily caused by bacteria, especially bacteria in the periodontal pocket below the gums and on the root surface, which is the direct cause of damage to periodontitis. Therefore, treatment for periodontitis requires subgingival scaling and root surface leveling in addition to supragingival scaling. Supragingival scaling can only remove bacteria and calculus on the tooth surface above the gingival sulcus, but only periodontal scaling and root surface leveling under the gingiva can clean up the dental calculus and bacteria in the periodontal pocket and its root surface, and can effectively treat periodontitis. Therefore, periodontal scaling is useful for periodontitis.
