Patients with symptoms of gum recession, need to identify the causes and then give symptomatic treatment, specific treatment is as follows: 1, with the age of the gums caused by recession generally do not need treatment, can be maintained through the periodontal health care to delay physiological recession; 2, if the gums are receding faster, to find the cause, if it is the brushing habits caused by the brushing habit may have to change the habit of brushing teeth. If the flossing method is wrong, correct the flossing method. If the gingival recession is caused by bad restorations or bad fillings, it is recommended that the patient removes the bad restorations or bad fillings. 3. For pathologic gingival recession, it can be handled with minimally invasive dental treatment alone or in combination with minimally invasive periodontal treatment. If root exposure leads to tooth sensitivity, tooth desensitization can be performed, and if severe, tooth repair is also required; 4. For those that have caused dental nerve symptoms, root canal therapy is likely to be required to achieve the goal of relieving the patient’s pain and dental nerve symptoms, and covering the exposed root surface with periodontal membrane gingival surgery.5. If the patient’s alveolar bone is too thin or there is bone dehiscence, the patient can also choose periodontal guided bone regeneration surgery for treatment.
