Generally, the tampon can be spat out about 40 minutes after the tooth extraction. Be careful not to bite the cotton rolls for too long. Some people think that the longer the bite the better, some people bite a few hours or even a dozen hours, this is wrong, but instead cause the wound to be saliva for a long time to soak, causing infection or poor coagulation.

　　2, patients with bleeding tendency, it is best not to leave temporarily after tooth extraction, to be half an hour after the doctor to look at the wound, whether the blood has stopped.
