Hello: During the process of tooth plastic surgery, structures such as periodontal ligament and alveolar bone will also undergo corresponding modifications. Some patients will experience mild loosening of teeth, soreness and discomfort, and weakness in chewing. These are all normal reactions during dental plastic surgery. In fact, after dental plastic surgery, the teeth are arranged neatly, which is beneficial to oral hygiene and can assist in the treatment of periodontal disease. In this sense, dental plastic surgery can prevent teeth from loosening as people age.
