You can wash your hair after wisdom tooth extraction, but you need to be careful not to use too hot water on the same day, otherwise it may cause bleeding after tooth extraction.
1. Blood clot will be formed in the extraction socket. Generally the blood clot is not stable enough within 24 hours, but the blood clot plays a vital role in the healing of the extraction socket.
2. Within 24 hours, if you wash your hair, take a shower, the head temperature will rise, due to the principle of thermal expansion and contraction, the blood vessels in the extraction socket will expand, the speed of blood flow will accelerate, which may wash out the newly formed blood clot, and the wound will bleed if there is a rupture. After re-bleeding, if the blood clot is not formed in time, it will cause the bone wall to be exposed, which will lead to dry socket syndrome and cause severe pain.
It is advisable to consult the visiting doctor for specific precautions after tooth extraction.
