The effect of the anesthetic used to remove wisdom teeth usually lasts about one to two hours. The time of expiration is also related to the individual’s physical condition. Wisdom tooth removal is the separation of the tooth from the jaw. The pain of the wisdom tooth removal process may be unbearable for the patient, so the doctor will give the patient an anesthetic, which will reduce the patient’s pain and the patient’s fear of tooth extraction will be less. The expiration time of the anesthetic is related to the health condition of the individual. Some people’s body may be particularly sensitive to anesthetic, and the anesthetic will take effect very quickly and the anesthetic will take a long time to work. Such patients will not feel the pain during the extraction and will feel the pain very late after the extraction. There are some patients who are not very sensitive to anesthetic and the onset of effect will be very late. Some people may also feel some pain during the extraction process. This is also because the anesthetic does not take full effect. Such people often do not really feel the effects of the anesthetic until after the tooth has been extracted. The amount of anesthetic injected during wisdom tooth extraction is very small and the time of expiration will be short compared to other procedures. The exact time varies depending on the individual’s health condition. If you want to know the exact time, patients can seek the help of their primary care physicians. Generally these doctors know the patient’s physical condition well and can make a good assessment.
