The technical term for scaling is supragingival scaling, which normally requires no anesthesia, except for a small percentage of patients with periodontal pockets. If anesthesia is used for supragingival scaling, it may require local anesthesia for the entire oral area of the teeth, which can easily lead to respiratory depression, cardiac arrest and other local anesthesia overdose problems. And during the process of supragingival scaling, patients usually do not have any discomfort symptoms, so under normal circumstances, supragingival scaling does not require anesthesia. However, if the patient has deep periodontal pockets, due to the close fit between the tartar and the bone on the root surface of the tooth, the bone may be removed along with the tartar during the supragingival scaling procedure, resulting in intolerable soreness and tenderness, so anesthesia is required at this time. Supragingival scaling is the process of removing tartar, plaque, and stains from the gums with a scaling instrument and buffing the surface of the teeth to delay the redeposition of plaque and tartar. Since the patient’s teeth will be sensitive to heat and cold after the supragingival cleaning procedure, it is recommended that the patient avoids eating foods that are too cold, too hot, too acidic, or too sweet, such as ice-cream, fondue, hawthorn, and cake, for 1 to 2 weeks after the supragingival cleaning procedure.
