Characteristic Symptoms
- Sudden, severe, electric-shock-like facial pain
- Usually one-sided, affecting the cheek, jaw, teeth, or around the eye
- Triggered by light touch — brushing teeth, shaving, eating, wind on the face, or even talking
- Episodes last seconds to a couple of minutes but can occur many times daily
- Pain-free periods between episodes (initially)
Causes
| Cause | Notes |
|---|---|
| Vascular compression | Most common cause — a blood vessel compressing the trigeminal nerve root |
| Multiple sclerosis | Younger patients or bilateral symptoms should raise suspicion |
| Tumour (rare) | MRI helps exclude this |
Treatment
| Treatment | Notes |
|---|---|
| Carbamazepine | First-line medication — very effective for most patients |
| Oxcarbazepine | Alternative with fewer side effects |
| Gabapentin/pregabalin | Second-line options |
| Microvascular decompression surgery | Definitive treatment — repositions the compressing blood vessel |
| Gamma knife radiosurgery | Non-invasive option, especially for those unfit for surgery |
Early Medication Response Confirms DiagnosisA dramatic, rapid response to carbamazepine is actually one of the diagnostic features doctors look for in trigeminal neuralgia — if the medication doesn't help significantly, other causes of facial pain should be reconsidered.
Is trigeminal neuralgia the same as a normal toothache?
No — though the pain can be mistaken for dental pain (leading some patients to have unnecessary dental extractions), the character (electric shock-like, trigger-sensitive, brief episodes) is quite distinct from typical dental pain.
Can trigeminal neuralgia be cured?
Microvascular decompression surgery offers the best chance of long-term cure by addressing the underlying vascular compression, with success rates around 70-90%, though it carries surgical risks that must be weighed against benefits.
