You cannot rinse your mouth immediately after tooth extraction, you need to wait for 24 hours before rinsing your mouth. Rinsing the mouth immediately after tooth extraction will cause the blood clot to fall off, and there will be repeated bleeding, aggravating the pain and affecting the healing of the wound. It is generally recommended to gargle 24 hours after tooth extraction, at this time the blood clot at the wound will be relatively stable, the local tissues gradually form granulation, at this time gargling is not easy to cause bleeding, but gargling action should not be too big or too fast, otherwise there is a possibility that the blood clot will fall off. Blood in sputum after tooth extraction is a normal phenomenon, and mild blood seepage in the extraction socket is also normal, but if the bleeding is heavy and can’t be stopped, go to the stomatological hospital in time for treatment. After tooth extraction, you should follow the doctor’s advice and rinse your mouth effectively under the doctor’s instruction. In terms of diet, choose some soft food or liquid food, such as egg custard, rice porridge, etc., do not choose hard food that is not easy to bite.
