1. It takes about half an hour to 45 minutes to spit out the gauze or cotton ball on the wound after tooth extraction. When biting gauze, if there is saliva, please swallow it normally. If the gauze still oozes slightly after being taken out, spare gauze 1 hour is needed. If it still fails, please contact your doctor again. It is normal to have a small amount of blood in saliva within 24 hours. If there is slight bloodshot saliva, there is no need to panic, but if bloodshot saliva continues to appear, please contact your doctor.
2, after tooth extraction, you can rest in a semi-recumbent position, don't lie flat, and you can't take a hot bath immediately to avoid bleeding from the wound.
It takes 2 hours to eat after tooth extraction. You can eat liquid or semi-liquid food instead of hard and overheated food. It must be noted that soft food should be eaten after 2 hours; Food should not be overheated, avoid chewing with the tooth extraction side. Otherwise, if we don't pay attention to the above points before the blood clot is completely organized, it will also lead to blood clot destruction and bleeding.

Contraindications
1, patients with cardiovascular diseases
Have serious cardiovascular disease and hypertension above 180/ 100 mm Hg. Generally, patients with heart disease can have their teeth extracted as long as they have no symptoms of cardiac insufficiency (such as mild activity or palpitation and shortness of breath when lying down). But when pulling teeth, we should do it: don't add adrenaline to anesthetic to avoid tachycardia and induce heart failure.
2, menstrual period
In principle, women should avoid tooth extraction during menstruation, because compensatory bleeding may occur in the alveolar cavity during menstruation. However, pulling out loose teeth during menstruation has little effect on patients. Such as impacted teeth or embedded teeth, should be removed after menstruation. According to some data, it is most suitable for women to have their teeth extracted around 10 day of menstrual cycle. At this time, the wound heals quickly and bacterial infection is not easy to occur.
