What is trigeminal neuralgia?

Trigeminal neuralgia is a condition in which the trigeminal nerve causes sudden, usually one-sided, very intense facial pain attacks that occur in brief episodes.

What commonly triggers an attack?

Simple actions like light touch to the face, brushing teeth, chewing, speaking or exposure to cold air are common triggers, though triggers vary between individuals.

Which specialist should I see first?

Evaluation typically starts with a neurologist; depending on findings, input from a pain specialist, neurosurgeon or dental professional may be recommended.

When should I go to the emergency department?

If you develop sudden new neurological symptoms — for example facial numbness or weakness, vision loss, balance or speech changes, or altered consciousness — seek urgent emergency care.

Trigeminal neuralgia

Trigeminal neuralgia describes sudden, stabbing facial pain on one side that arises from the trigeminal nerve. This page offers general information about typical symptoms, possible causes, diagnostic pathways and practical considerations that can affect daily life.

How trigeminal neuralgia typically feels

Pain usually appears as very intense, short-lived attacks — often described as electric shocks or knife-like stabs — affecting the cheek, jaw or forehead on one side. Attacks can last seconds to minutes and may come in clusters; between attacks there may be no pain or only mild discomfort.

Key symptoms and distinguishing features

Typical features include strictly one-sided, recurrent brief attacks, reproducible triggers (light touch, brushing teeth, speaking), and sequences of attacks. Conditions such as dental problems, sinusitis or temporomandibular joint disorders can produce similar facial pain, so clinicians consider these in the differential diagnosis.

Causes and common triggers

Many cases are linked to compression of the trigeminal nerve root by a blood vessel or changes in the nerve’s surrounding tissues. Less commonly, demyelinating diseases or facial trauma may be involved. Typical triggers reported by people include light facial touch, cold air, chewing, speaking and dental procedures.

Diagnosis and which specialist to consult

Diagnosis is primarily based on clinical history and neurological examination. If needed, imaging such as MRI can assess nerve surroundings and rule out other causes. Initial assessment is commonly by a neurologist; pain clinics, neurosurgery and dental specialists may be involved for multidisciplinary evaluation. This page does not provide personal medical advice—see a specialist for tailored assessment.

Impact on daily life and practical tips

Identifying personal triggers and avoiding them when possible can improve quality of life. Attention to sleep, stress management, eating habits and oral hygiene may help reduce the burden of attacks. Seek urgent medical care if you develop new neurological signs such as facial numbness or weakness, vision changes, balance problems, speech changes or altered consciousness.
