Dental surgery is usually painful during anesthesia, but the pain is short-lived and is mainly caused by the needle being inserted into the soft tissues of the tooth. 1. Before dental surgery, local anesthesia is usually administered. When the needle is inserted into the soft tissues of the tooth, it stimulates the nerves and causes pain, which is usually short-lived. After the anesthesia has taken effect, no pain will be felt when the teeth are treated, so patients do not need to worry and fear too much. 2. After dental surgery, local pain will occur when the anesthesia fails to work. If patients do not tolerate it, they can take oral painkillers and apply cold compresses locally to relieve the pain. Commonly used painkillers are ibuprofen or fenbendazole, which should be used under doctor’s guidance. Local cold compresses have the effect of relieving pain and reducing swelling. Patients who need dental surgery should choose to have it done in a regular dental hospital or in the dental department of a regular hospital.
