There are certain risks associated with the adjacent neural tube during eruption and removal of the blocked tooth, as follows. 1. Emergence: The movement of the erupting teeth in the jawbone may press on the nerves in the adjacent neural tube, causing pain, numbness, and other symptoms in the nerve distribution tissues. 2. Removal of retained teeth: when removing retained teeth adjacent to the neural tube, it is easy to injure the nerve, resulting in nerve edema or even fracture, which will affect the sensation and function of the innervation, such as mandibular retained wisdom teeth from the mandibular neural tube close to the mandibular nerve, the removal of the damage to the mandibular nerve will result in numbness of the innervated parts of the nerve, etc. If the retained teeth are farther away from the neural tube, it will cause pain and numbness. If the wisdom teeth are close to the nerve canal, or if other symptoms occur, it is recommended to go to the hospital in time to assess the risk of wisdom teeth removal with the help of the doctor, and to carry out targeted treatment.
