Question

Difference between tooth pain and trigeminal neuralgia

Answer 1

Answer:

Explanation:

Trigeminal neuralgia (TN) presents as a stabbing unilateral facial pain that is triggered by chewing or similar activities or by touching affected areas on the face. ... They complain of an unrelenting sinus pain or toothache lasting for hours, triggered by moving the jaw or drinking fluids.

Answer 2

Explanation:

There are some of the features which make trigeminal neuralgia peculiar:

1. Pain occurs along the course of the nerve

2. Pain occurs spontaneously without obvious cause.

3. Presence of trigger zone is characteristic of the disease.

But at times it is difficult to distinguish it with dental pain. Diagnostic test would be nerve block.

I would add the following to the points mentioned by Jamal: neuralgic pain is always unilateral and always well-localized. It is of the severe type that could be lancinating, stabbing or electric-shock like. Its duration is seconds that may rarely extend to 2 minutes. Patients may also describe a back ground pain between attacks. It does not disturb sleep. Neuralgia is usually idiopathic but it may be associated with certain diseases especially if your patient is young, say in thirties, so they should be investigated for multiple sclerosis, HIV, or brain tumor. Patients with trigeminal neuralgia may have good response to anticonvulsants particulary tegretol, phenytoin, and sodium valproate.

On the other hand, dental pain is way more common than neuralgia,so before jumping to the diagnosis of neuralgia you should examine the patient properly clinically and by radiographs to exclude any inflammatory problem in the teeth or periodontium.
