It is not recommended to rinse the mouth with mouthwash only after 24 hours of tooth extraction. Rinsing the mouth prematurely will cause the loss of blood clots in the extraction sockets, because blood clots are the basis of tissue regeneration and healing, and if the blood clots fall off, it will easily cause dry socket and make the wound infected, which will lead to delayed wound healing. After 24 hours of tooth extraction, it is recommended to rinse with mouthwash with anti-inflammatory function, such as rinse with tinidazole, but the strength of rinse should not be too strong. After tooth extraction, you should not chew food on the side of the extracted tooth too early to prevent infection of the extraction wound. Within 3-5 days after tooth extraction, it is recommended to take oral anti-inflammatory drugs to prevent infection of the extraction wound, and oral cephalosporin and metronidazole tablets can be taken to prevent wound infection.
