Although they are called “wisdom teeth,” they have nothing to do with IQ except for the pain that affects the ability to think during a pericoronitis attack. A wisdom tooth is just an ordinary tooth, and the pulp contains only branches from the alveolar nerve, in addition to blood vessels and connective tissue. The dental nerve contained in the pulp is the nerve endings of the inferior alveolar nerve, which comes from the mandibular nerve and is a branch of the trigeminal nerve. Although the trigeminal nerve is a branch of the cranial nerve, its main function is to control the sensation of pain, warmth and touch in the face and to control chewing movements, and it has nothing to do with intelligence or memory. Some patients feel that their memory will become worse in the short term after wisdom tooth extraction, most likely because of the misleading name “wisdom tooth”. In addition, the temporary discomfort may also be caused by the anesthetic used during the extraction, as well as the relatively strong pain and noise stimulation.
