You should not brush your teeth or rinse your mouth for the first two days after the tooth is extracted. You should not use too much force when rinsing because too much force may cause the blood clot in the socket to be rinsed off, which may affect the healing process. When you brush your teeth, try not to stimulate the clot too hard, but gently brush around the fossa, and focus on the teeth around the fossa to protect the clot as much as possible.
