Orofacial pain and nerve conditions

Some face and mouth pain is nerve-related rather than dental. Recognising that early prevents unnecessary treatment on healthy teeth and gets the right care started.

What it is

Not all face pain comes from teeth, and one of the most valuable things a careful dental assessment does is recognise when it does not. People with nerve-related face pain frequently arrive having already had fillings, root canals or extractions on perfectly healthy teeth, because the pain felt exactly as though it came from there.

Trigeminal neuralgia is the clearest example: sudden, severe, electric-shock pain on one side of the face, lasting seconds, triggered by light touch, chewing, cold air or brushing. Between attacks there is often nothing. It does not behave like toothache, and it does not respond to dental treatment — it is managed medically, and a dentist's job is to recognise it and refer.

Other patterns include burning mouth syndrome, where the tongue and mouth burn without any visible cause; persistent pain that continues after a tooth has been treated or removed and the site has healed; and pain referred from elsewhere, including the jaw muscles, the sinuses, the neck, and occasionally the heart, where jaw pain can be a warning sign that needs urgent attention.

The approach is to be thorough before intervening. A tooth is not treated on suspicion alone when the pain does not fit a dental pattern. Where the picture points away from the teeth, the referral is to a neurologist or orofacial pain specialist, and care is shared rather than handed over — because dental factors like clenching often sit alongside the nerve problem.

You may need this if…

• Sudden electric-shock pains on one side of the face, triggered by touch or cold
• Burning of the tongue or mouth with nothing visible to explain it
• Pain that continued after a tooth was treated or removed and healed
• Pain that moves, or does not correspond to any one tooth
• Numbness or altered sensation in the lip, chin or tongue
• Face pain with headache, visual change or other neurological symptoms

What happens, step by step

1. A careful history

   The character of the pain, what triggers and relieves it, how long each episode lasts, and what treatment has already been done. This is the single most useful part.

2. Ruling out dental causes properly

   Examination, vitality tests and X-rays, so that a genuine dental cause is not missed — and so that a healthy tooth is not treated on suspicion.

3. Recognising the pattern

   Whether the picture fits nerve pain, muscular pain, joint pain, sinus involvement or referred pain from elsewhere.

4. Referral where indicated

   To a neurologist or orofacial pain specialist. Some patterns — new severe headache, numbness, neurological signs — are referred urgently.

5. What we manage here

   The dental contributors: clenching and grinding, a night guard, jaw muscle care, and treating any genuine dental problem found alongside.

6. Shared follow-up

   Keeping in contact so treatment is coordinated rather than duplicated, and so nothing is done to teeth unnecessarily.

Looking after it afterwards

• Keep a simple diary — when the pain comes, how long it lasts, what set it off. It is genuinely useful at the next appointment.
• Take medication prescribed by the specialist as directed; these are not painkillers taken as needed.
• Avoid known triggers where you can during a flare-up.
• Come back before agreeing to any further dental treatment for this pain elsewhere.
• Seek urgent care for sudden severe headache, weakness, numbness or visual change.
