ICD-11 DA0F.0 — Burning mouth syndrome

Chronic burning mouth pain is chronic orofacial pain with an intraoral burning or dysaesthetic sensation that recurs for more than two hours per day on 50 % of the days over more than three months, without evident causative lesions on clinical investigation and examination. It is characterised by significant emotional distress (anxiety, anger/frustration or depressed mood) or interference with orofacial functions such as eating, yawning, speaking etc. Chronic burning mouth pain is multifactorial: biological, psychological and social factors contribute to the pain condition. The diagnosis is appropriate independently of identified biological or psychological contributors unless another diagnosis would better account for the presenting symptoms.

The diagnosis excludes nothing.

It has no clarifying diagnoses.
