You should not rinse your mouth on the day of wisdom tooth extraction, and you should only brush and rinse your mouth after 24 hours after wisdom tooth extraction. Because wisdom teeth usually cause relatively large damage to soft and hard tissues during the extraction process, a certain degree of facial redness and pain will be caused after the extraction. If you brush and rinse your mouth too early, it will easily lead to the dislodging of blood clots and infection in the extraction sockets. Once the clot is dislodged, the healing of the extraction wound will be delayed after the clot is dislodged because the clot is the basis for tissue regeneration and healing. If the infection of the blood clot in the extraction socket occurs, it will easily lead to dry socket, which will cause severe pain, so brush and rinse your teeth only after 24 hours after wisdom tooth extraction. At the same time, after wisdom tooth extraction, you should also do an appropriate amount of anti-inflammatory treatment, you can take oral cephalosporin and metronidazole tablets to reduce inflammation. When the soft tissue wound after wisdom tooth extraction has not completely healed, it is not recommended to chew food on the affected side of the tooth extraction to avoid infection of the extraction wound.
