Scaling is often referred to as periodontal scaling, which is a basic periodontal treatment that further removes soft tartar, tartar and plaque from the gums. Because sharp instruments are used to reach into the periodontal pockets, it can be painful and is usually performed under local anesthesia. Without anesthesia, the patient’s experience will be more painful, so local anesthesia is required. Nowadays, local anesthetic drugs have almost very little effect on the whole body, so you can safely use local anesthesia without worrying about any side effects. Because scraping is still painful, it needs to be performed under local anesthesia.
