The swelling of the face on the second day after wisdom tooth extraction is a very common clinical situation, and there is no need to worry about it at all, because wisdom tooth itself is relatively the most difficult tooth to be extracted in maxillofacial alveolar surgery, so the extraction is correspondingly more traumatic. When the human body receives some big trauma, there will be swelling for a period of time, and this swelling itself has a certain delay, not swelling will appear after the trauma, but swelling will start after the trauma has passed for some time, and the swelling will last for a period of time, usually about 2-3 days, and then the swelling will gradually decrease. In other words, the swelling will start on the second day after wisdom tooth extraction, and then the swelling will gradually subside directly after 2-3 days. So some people will say that the face shrinks after wisdom tooth extraction, which is actually a misunderstanding and a wrong statement.
