Under normal circumstances, the blood clot cannot be dislodged because the healing of the extraction wound is mainly due to the healing of the blood clot. Within 1 week after the initial formation of the clot, the gingival tissue and bone tissue will have started to mechanize, and will slowly return to normal in 2 months. If the blood clot is dislodged, it is important to go to the hospital as soon as possible, as this time can easily cause infection of the extraction wound, causing pain and bacterial infection to the patient. Therefore, after tooth extraction, you must strictly follow the doctor’s medical advice to bite the dry cotton ball, not to brush and rinse your teeth within 24 hours, and not to exercise strenuously, all of which play an important role in the protection of the blood clot.
