Scaling has no side effects. Scaling is also called ultrasonic scaling, and it is a routine clinical treatment for gingivitis and periodontitis. Scaling can completely remove tartar and plaque from periodontal pockets, create a good oral hygiene environment and treat gingivitis and periodontitis. Scaling uses high-frequency ultrasonic shock to break up tartar, so the process of scaling will cause slight scratches on the surface of tooth enamel, so polishing of the tooth surface should be done after scaling to make the scratches very smooth and restore the original shape of tooth enamel. Therefore, it is important to go to a regular hospital for scaling to prevent cross-infection, and to avoid excessive damage to the enamel by the regular hospital doctors with regular and gentle techniques.
