In general, a wisdom tooth extraction involves either local or sedation anaesthesia, according to Mayo Clinic. The dental surgeon makes an incision in the gum to extract the tooth. Recovering patients should expect some localized pain and swelling after a wisdom tooth extraction. These symptoms usually last for about two days or up to a week after the operation, notes RCS.
A dental surgeon may use local anaesthesia to numb the area around the tooth that is being extracted. In operations involving more than one wisdom tooth, general or sedation anaesthesia is often used, according to WebMD. With sedation anaesthesia, the patient is unconscious for the duration of the procedure.
During a wisdom tooth extraction, the dental surgeon makes an incision in the gum and removes a small part of the bone that blocks access to the tooth's roots, explains Mayo Clinic. The surgeon then removes the tooth, sometimes by cutting it into a number of smaller sections to make extraction easier. Once the tooth has been removed, the surgeon clears the wound of any remaining debris. The wound is usually closed with stitches, and gauze is placed in the mouth to staunch the bleeding.
After a wisdom tooth extraction, the patient usually experiences pain and a small amount of localized swelling. In some cases, the jaw may be stiff and bruises may appear around the jaw area, according to RCS. The patient should avoid hard or crunchy foods for the first few days after the extraction.
