Most people have wisdom teeth, which are part of the normal dental development process, and there is no such thing as a good thing. Wisdom teeth are not harmful if they have a chewing function and do not affect the neighboring teeth; otherwise, it is recommended to consult a doctor for extraction. Wisdom teeth (clinically known as third molars) have less space for eruption due to evolutionary reasons and are prone to eruption abnormalities; if the growth of wisdom teeth is skewed, resulting in recurrent inflammation of the gums around the crown and affecting the neighboring normal teeth, or if the wisdom teeth do not have opposing teeth and are elongated and susceptible to food inclusions, it is recommended that they be extracted in a timely manner by medical treatment. In addition, if the wisdom teeth can erupt normally and have certain chewing function, it is not harmful to human body and can be used as normal teeth; however, due to the backward position of the wisdom teeth, it is recommended to do a good job of oral cleaning to avoid wisdom teeth caries and even painful symptoms.
