You can usually brush your teeth normally 48 hours after tooth extraction. 1. Under normal circumstances, you can’t brush your teeth on the day after tooth extraction, and you can brush your teeth normally after 24 hours. The reason is that blood clot will be formed on the wound surface after tooth extraction, if you brush your teeth too early, it will easily lead to the rinsing off of the blood clot, which will easily bleed again, and will also easily cause infection, pain and other symptoms. If there is pain and bleeding, it is recommended to brush your teeth after 48 hours. 2. After tooth extraction, patients should try to eat mainly fluids, quit drinking, avoid spicy and stimulating, raw and cold food, and eat more fresh fruits and vegetables to increase their resistance and immunity. Brush your teeth gently to avoid hard bristles that may rub the wound and cause new bleeding or aggravate the pain. After tooth extraction, you should follow the doctor’s instructions, strictly enforce the time of brushing and rinsing, and brush your teeth to avoid the tooth extraction wound.
