You can brush your teeth on the 3rd day of wisdom tooth extraction, and you can brush your teeth and rinse your mouth normally 24 hours after wisdom tooth extraction. However, because there is a certain degree of soft and hard tissue damage during wisdom tooth extraction, the reaction after extraction is usually more severe than after other teeth are extracted. After wisdom tooth extraction, you should brush your teeth gently and not rinse your mouth too hard to prevent dislodging the blood clot in the wisdom tooth extraction socket, which is the basis for tissue regeneration. If the blood clot becomes infected or is dislodged, it can cause dry socket syndrome, which prevents the extraction wound from healing. Wisdom tooth extraction surgery can also be used with anti-inflammatory function of mouthwash to gargle, such as the use of tinidazole gargle to gargle, which can also reduce the number of disease-causing bacteria in the mouth, to prevent the infection of the extraction wound, and at the same time the patient can also take the appropriate amount of anti-inflammatory anti-inflammatory drugs to anti-inflammatory, such as oral cephalosporin and metronidazole tablets to prevent the infection of the extraction socket.
