1. After tooth extraction, the doctor will put a few cotton balls on the tooth extraction wound, let the patient bite tightly, spit it out after half an hour to 40 minutes, and don't rinse your mouth or brush your teeth for 24 hours. In this way, the tooth extraction wound should generally not bleed again, but it is normal to have a little bloodshot in saliva.
2. After pressing for hemostasis for half an hour to 40 minutes, blood clots will appear at the tooth extraction site. If the blood clot at the wound falls off, the amount of bleeding will increase, and the patient will not only suffer, but also cause infection. Therefore, patients should not brush their teeth and rinse their mouths within one day after tooth extraction to prevent blood clots from falling off; Avoid eating overheated food or drinking hot water, otherwise it will promote wound bleeding; You can't lick the wound with your tongue or your mouth, which will increase the possibility of bleeding after tooth extraction.
In addition, patients with other diseases should truthfully introduce their condition to the doctor before tooth extraction. For example, some patients with hematological diseases will have greater bleeding and infection tendency after tooth extraction when their condition is out of control. After injection of anesthetic 1 ~ 3 hours, the effect of anesthetic will disappear and many patients will feel pain. At this time, you can take a small amount of painkillers.
4. At the same time, try to avoid eating with the teeth on the extraction side, and don't eat hard food to prevent food residues from falling into the extraction wound. But if the wound still hurts after a few days, you should go to the hospital for examination immediately.
