There is no need to kill the nerve for a tooth extraction.
Tooth extraction refers to the removal of the entire piece of tooth tissue, and the nerve is in the root canal inside the tooth tissue, so it can be directly removed together with the nerve in the pulp, without the need to remove the nerve first. Moreover, the tooth extraction is performed under perfect anesthesia, and after the anesthesia has taken full effect, there is usually no pain during the tooth extraction process.
Women need to avoid menstruation to avoid bleeding. Avoid extraction on an empty stomach or when there is inflammation in the mouth, otherwise it may cause low blood sugar, low blood pressure, increased inflammation and other conditions.
After the tooth extraction treatment, you need to bite gauze pressure to stop bleeding according to the physician’s instructions, and pay attention to take medication treatment on time to avoid local bleeding and infection. Within 24 hours after tooth extraction, it is normal to have blood in saliva, and if there is a lot of bleeding, you need to go to the hospital in time.
