What causes trigeminal neuralgia?

  1. Dental caries

  2. Viral infection

  3. Pressure on the trigeminal nerve or Multiple Sclerosis

  4. Poor oral hygiene

The correct answer is: Pressure on the trigeminal nerve or Multiple Sclerosis

Trigeminal neuralgia is a type of nerve pain that affects the trigeminal nerve, which runs from your forehead to your jaw on both sides of your face. The most common cause is pressure on the trigeminal nerve, often due to a blood vessel pressing down on the nerve. This can be caused by multiple sclerosis, a condition that damages the protective coating of nerves. While dental caries and poor oral hygiene may lead to dental pain, they are not directly related to trigeminal neuralgia. Viral infections, such as shingles, can also cause nerve pain, but are not considered a frequent cause of trigeminal neuralgia. Therefore, option C, pressure on the trigeminal nerve or multiple sclerosis, is the most accurate answer to the question.
