Dental sandblasting removes residual fine tartar and restores the smoothness of the tooth surface after cleaning, helping to control periodontal inflammation and maintain the effectiveness of periodontal treatment, as described below. Supragingival scaling is a basic treatment component of gingivitis and periodontitis, and ultrasonic scaling is commonly used today. However, tartar cleaning may be missed, and the working head of the ultrasonic scaler produces scratches on the tooth surface, which can easily lead to plaque adhesion and cause recurrence of gingivitis or periodontitis. Auxiliary sandblasting after periodontal treatment can remove hidden fine tartar and restore the smoothness of the tooth surface, which can significantly reduce the re-attachment of plaque, obtaining good treatment results and long-term efficacy maintenance.
