Matters of postoperative care for dental implants: 1. Routine use of antibiotics after surgery. For simple implant surgery (small number of implants, short surgery time, good recovery of patient), oral antibiotics will be administered after surgery, while complex implant surgery requires intravenous antibiotics to prevent infection. 2. Do not brush your teeth and rinse your mouth with water for 24 hours after surgery, because over-frequent rinsing may cause the teeth to bleed, but rinse your mouth with mouthwash after meals to prevent residual food residue in your mouth. 3.Patients generally have only slight hidden pain or discomfort after surgery, no need to take painkillers, but if patients are sensitive or feel local pain, you can add painkillers on the day after surgery, the general normal situation is that 24 hours after surgery, patients will no longer have continuous pain sensation. 4, due to the different physical and surgical procedures of patients, there may be different degrees of surgical reactions, some patients have light reactions or no uncomfortable reactions, some will have local edema and ecchymosis, which usually lasts about 3-5 days. 5.The stitches will be removed in 7-10 days after the normal operation, and timely removal of stitches can prevent local infection.
