The holes after wisdom teeth extraction are mostly called extraction sockets clinically. The extraction sockets will heal gradually, but care should be taken to protect the wounds. You should not eat or drink for 2 hours after extraction, you should not brush your teeth or rinse your mouth for 24 hours, and you should eat a liquid or semi-liquid diet for nearly a week, and you should eat a light diet.
The extraction socket will be the first to form a blood clot, about 30 minutes to coagulate, so it is generally necessary to bite the cotton roll for half an hour for pressure to stop bleeding. You should not eat or drink for 2 hours after tooth extraction, and you should not brush your teeth or rinse your mouth for 24 hours. Generally about a week the surface of the extraction socket will form a soft tissue closure. Therefore, it is important to eat a light diet until a liquid or semi-liquid diet is available for nearly a week, etc.
If the holes do not heal for a long time after wisdom teeth extraction, hospitalization is recommended.
