There is no direct relationship between scaling and ulcers. Scaling does not reduce or aggravate ulcers. Oral ulcers are the most common disease of the oral mucosa and are commonly characterized by recurrence and self-limitation. Recurrence means that it is difficult to be cured clinically, while self-limitation means that even without special treatment, it will naturally improve in about 1-2 weeks. Scaling is a professional cleaning process for periodontal plaque and calculus, and there is no relationship between it and ulcers. If the ulcer occurs on the lip, the scaling process will stimulate the ulcer and cause more severe pain, but if the patient can tolerate the pain, the scaling is also possible.
