Smoking is generally not allowed after dental implant surgery. Dental implant surgery involves placing an implant into the body to form an osseointegration and then making a crown on the outside. The patient’s action of smoking will easily lead to bleeding and increase the chance of infection, while there will also be wounds exposed after removing the stitches, which will easily lead to inflammation of the patient’s wounds. It is recommended that the patient’s postoperative diet is based on light and easily digestible food, such as millet porridge, soybean soup, etc., avoid spicy and stimulating food, while paying attention to postoperative rest and oral cleaning after meals, avoiding strenuous exercise in the oral cavity, and forbidding smoking, drinking and so on. It is recommended that patients go to the hospital for regular checkups, pay attention to postoperative care, maintain oral hygiene and cleanliness, and pay attention to postoperative rest.
