Generally a day after the extraction of teeth without rinsing can be, normal post-extraction medical advice is to advise patients not to brush their teeth, rinse their mouths, do not use their tongues to lick the extraction wounds, and do not suck the extraction wounds, and at the same time as little as possible to do strenuous exercise. For the extraction wound, the newly formed extraction wound is relatively fragile, especially the blood clot inside is not fully stabilized, premature brushing and rinsing may lead to the release of the blood clot and cause bleeding from the extraction wound. However, after 24h, the blood clot has been stabilized, and the granulation tissue in the oral cavity has begun to grow, then you can brush your teeth and rinse your mouth normally, and there is no need to worry too much. For brushing teeth, try not to take the bristles and brush head deep into the extraction wound, in most cases the risk is very small.
