Dr. Chen Tielou answered that he performed a flap surgery on you. This operation is to scrape out the deep periodontal pockets that cannot be removed by curettage through the flap. It is a periodontal pocket. It is a kind of surgery that does not need to be performed when the periodontal pocket is deep. If the periodontal pocket is very deep and there are many foreign objects in the pocket, it will aggravate the development of periodontal disease and increase bone resorption. Therefore, you should still do it when you should do it. However, the side effects of flap surgery are that the gums will shrink to a certain extent after the surgery, and the interdental space will become larger, especially the front teeth, which will affect the appearance. Please refer to the articles on my personal website about flap surgery. Now that you take supplementary nutrition and rest, your gums will not grow back to their original position.
