The duration of swelling after dental implant surgery varies from person to person, depending on the complexity of the surgery, the patient’s constitution, and the measures taken, and cannot be generalized. Since dental implant surgery is an oral surgery, the blood supply to the soft tissues in the oral cavity is rich, so swelling usually starts to appear from the postoperative period, reaching a peak in 24-48 hours, and in some patients in 72 hours, and then the swelling will gradually decrease. If the patient is in good health and the surgery is not very complicated, the postoperative swelling can last for 3-5 days and anti-inflammatory drugs are usually not required. If the patient is in poor health and the surgery is complicated, the swelling may last 7-14 days after the dental implant surgery and oral anti-inflammatory drugs and pain medication may be appropriate. After dental implant surgery, you can apply local cold compresses, or take oral or static dexamethasone and other drugs to prevent tissue edema. If swelling is already present, a local hot compress can be applied 36-48 hours after the procedure to promote the swelling to subside. After the dental implant surgery, the patient usually does not need to be hospitalized and can eat warm and soft food on the same day.
