Bruising after wisdom teeth extraction does not require special treatment, and can be left to recover naturally. 1. Wisdom teeth are located at the end of the tooth row, most of them are malpositioned or completely buried and blocked, and most of them need to be surgically incised and extracted. 2. When removing wisdom teeth, local anesthesia is required, mucous membrane is cut, part of the bone is removed, and the crown is separated from the tooth and other steps are taken to remove the tooth. Due to the rich blood flow in the oral cavity, the capillaries are intertwined and intersected, and more blood leaks out during surgical incision, which will result in bruising of the local neighboring tissues and cause bruising, which is generally a normal postoperative reaction. 3. Post-operative bruising generally does not require special treatment, with the extension of time, it will gradually repair itself. If there is any abnormality after wisdom teeth removal, it is recommended to follow up in time, and under the guidance of the doctor for examination and treatment to avoid any adverse effects.
