Periodontal surgery is an advanced treatment plan for patients with severe periodontal disease. When non-surgical treatment cannot effectively control periodontal disease, we will consider proceeding with surgical treatment. This type of treatment includes procedures such as flap surgery, bone grafting, or tissue regeneration. During surgery, the dentist will carefully remove the deep infection and restore damaged dental fissures and bone tissue. Although the recovery period may take several weeks, surgical treatment can significantly improve periodontal health and prevent further bone loss and tooth decay. This type of treatment can not only save threatened teeth, but also create favorable conditions for future dental implants or other restorative treatments.
