This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This exact-topic Canadian dental clinical resource supports recognition, exclusion of dental pathology and specialist referral. It is not a current pan-Canadian neurology guideline; medicine initiation and surgical selection are outside this summary.

Source-attributed clinical priorities

  • Confirm brief, unilateral, shock-like attacks in a trigeminal distribution and identify sensory loss or atypical continuous pain.
  • Obtain specialist assessment and imaging when secondary disease is possible, particularly in younger or atypical presentations.
  • Use the exact-topic dental resource for recognition and referral, not as authority for a national medicine or surgical algorithm.
  • Brief triggered unilateral pain in a trigeminal distribution is compatible with trigeminal neuralgia, but local dental and oral disease must be excluded.

Practical assessment and management workflow

1
Characterize attack duration, division, triggers, pain-free intervals, continuous pain and dental history.
2
Perform a complete head, neck, oral, dental and cranial-nerve examination before assigning a neuralgia diagnosis.
3
Use this Canadian dental resource to recognize a compatible pattern and refer for medical diagnostic work-up rather than presenting it as a national prescribing rule.
4
Refer atypical features, sensory deficit, diagnostic uncertainty or uncontrolled pain to neurology, oral medicine or neurosurgery as locally available.

Safety, red flags and urgent escalation

  • New facial weakness, objective sensory loss or multiple cranial neuropathies needs expedited imaging.
  • Severe oral pain with swelling or systemic illness may be dental infection rather than neuralgia.
  • Do not perform irreversible dental procedures without a demonstrated dental cause, and do not infer medicine doses from this source.
