In the clinic
Anesthesia of the inferior alveolar nerve is widely practiced by most dentists. The inferior alveolar nerve is one of the largest branches of the mandibular nerve [V3], carries the sensory branches from the teeth and mandible, and receives sensory information from the skin over most of the mandible.
The inferior alveolar nerve passes into the mandibular canal, courses through the body of the mandible, and eventually emerges through the mental foramen into the chin.
