Nervous Innervations of the Lower Teeth Case Study

Nervous Innervations of the Lower Teeth - Case Study Example As the paper highlights, the mandibular nerve (MN) is a division of the TGG that further branches into the alveolar nerve. The alveolar nerve branches into the mylohoid nerve, alveolar artery, and finally the incisive nerve that provides sensory innervations to the premolar teeth. The loss of feeling in the tongue, dry mouth and change in taste is caused by alveolar nerve block due to the anesthetic effect. This may also be due to chemical damage to the lingual nerve because of direct injection of a neurotoxic local anesthetic such as articaine, procaine, lidocaine, tetracaine and bupivacaine. The loss of taste is caused by the anesthetic effect caused by injuries to the lingual nerve during the dental work. The lingual nerve is anesthetized during an alveolar nerve block. The lingual nerve transfers gustatory fibers responsible for taste sensation to the anterior part of the tongue. Saliva has also been linked by research to taste response where a low flow affects taste sensation. T he motor function of the tongue is not interfered with because the mandibular nerve has an additional motor component that runs separate to the facial component. This provides sensory communication between the myoholid nerve and the lingual nerve that controls motor functions of the tongue.
