Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which cranial nerve is numbed by the dentist when you’re getting a cavity filled?
A
Occulomotor
B
Trigeminal
C
Facial
D
Glossopharyngeal
Explanation: 

Detailed explanation-1: -The mandibular branches of the trigeminal nerves help you bite, chew and swallow. In some cases, people develop numbness or other signs of trigeminal neuropathy from an accident, dental procedure or facial surgery.

Detailed explanation-2: -Damage to branches of the trigeminal nerve following maxillofacial surgery and dental treatment is unfortunately common, in most cases the symptoms are transient and patients fully recover sensation over time. Persistent nerve damage results in severe complications such as neuropathic pain and trigeminal neuralgias.

Detailed explanation-3: -Trigeminal neuropathic pain is a condition that occurs when one or more branches of the trigeminal nerve are injured. It results from a nerve injury following a dental procedure and other facial injuries. The pain is usually constant and commonly accompanied by a burning or crawling sensation.

Detailed explanation-4: -Pain in the trigeminal system, including dental pain, is ‘special’. Not only is the trigeminal nerve the largest sensory nerve in the body, represented by over 50% of the sensory cortex, but it is the only sensory nerve with an intracranial distal root ganglion: the trigeminal ganglion.
