It is of course possible to brush your teeth 2 days after tooth extraction, and you can brush your teeth normally. It is recommended that you can brush your teeth 24 hours after tooth extraction, because relatively 24 hours after tooth extraction, the blood clot in the tooth extraction wound has stabilized and the tooth extraction wound has started to grow granulation tissue. If you brush your teeth at this time, there will not be much risk as long as you do not deliberately push the brush head or bristles deeper into the extraction wound. However, within 24 hours after tooth extraction, you should be careful not to brush your teeth, not to rinse your mouth, not to suck on the wound, not to lick the wound with your tongue, and not to do strenuous exercises because they may cause stimulation to the blood clot in the wound and cause the clot to fall off and cause secondary bleeding.
