Burning mouth syndrome (BMS) causes persistent or recurrent burning, tingling, or altered taste in the mouth. This page outlines typical symptoms, possible contributing factors, and which health professionals may help. For an individual diagnosis and care plan, consult a healthcare provider.
How it feels and common symptoms
People with burning mouth sensations often report pain or burning on the tongue, roof of the mouth, inner lips or across the whole mouth. Symptoms can include tingling, a metallic or bitter taste, and a dry mouth sensation. Symptoms are often mild in the morning and may intensify through the day; they can sometimes be linked with stress or certain foods.
Possible causes and risk factors
There is no single cause for BMS. Contributing factors may include hormonal changes (for example during or after menopause), neuropathic changes, increased sensitivity of the oral mucosa, nutritional deficiencies, chronic conditions, medication effects, or dry mouth. Gastroesophageal reflux and local oral health issues can also influence symptoms. Each case is different and needs professional assessment.
Diagnosis and which specialists to consult
Initial assessment usually starts with a detailed history and an oral examination. A primary care physician or a dentist is a common first contact. If needed, referrals may be made to ENT (ear, nose and throat), neurology, endocrinology, dermatology (including Dermatology and Venereal Diseases), or Infectious Diseases and Clinical Microbiology for specialized evaluation. Investigations can include blood tests to check for deficiencies or systemic causes, oral inspection, taste tests, and imaging when indicated.
Managing symptoms day-to-day
Practical measures that may reduce discomfort include good oral hygiene, avoiding very hot, spicy or acidic foods, maintaining hydration, and reducing tobacco and alcohol. Balanced nutrition and stress-management techniques can also help. These are general suggestions; if symptoms are persistent or worsening, seek professional advice. If you experience severe swelling of the face or throat, trouble breathing or swallowing, seek emergency medical care.
