The wisdom tooth is the third molar in the alveolar bone in the human mouth. It looks like other molars, and is divided into a crown, a root and a neck. However, because most people’s wisdom teeth do not erupt properly and only partially erupt, they do not look like other molars. There are four wisdom teeth in the upper and lower jaws, and they usually erupt between the ages of 16 and 28, although some people may erupt later or not erupt for life. If the wisdom teeth erupt normally, there is enough space for them to live and they do not affect the health of other teeth, there is usually no pain or inflammation, they can bite and chew normally, and they do not have a negative impact on the body and do not need to be treated. However, because of the limited jawbone area, wisdom teeth always erupt last and are prone to insufficient growth space, leading to obstruction. Abnormally erupted wisdom teeth can cause decay of adjacent teeth, pericoronitis, bite disorder, temporomandibular joint discomfort, etc., which can easily endanger oral health, so wisdom teeth need to be extracted in time. When wisdom teeth obstruction causes inflammation or pain, it is recommended to seek medical attention in time, mainly by traditional obstructive wisdom teeth extraction, through local anesthesia, local gingival incision, after knocking and prying and other techniques, the root of the tooth is removed, the local alveolar groove is cleaned, reset and then sutured, the operation can be completed.
