Burning Mouth Syndrome (BMS) is characterized by a burning or stinging sensation on the tongue, lips, or oral mucosa without any visible lesions. It is more common in post-menopausal women over 50 years of age. BMS occurs when the trigeminal nerve is hypersensitive, often along with dry mouth (xerostomia) or a metallic taste. Potential causes include local factors like ill-fitting dentures, systemic conditions such as vitamin deficiencies or Sjogren's Syndrome, and psychological issues like depression or anxiety. Treatment focuses on reducing pain and discomfort through analgesics, mouthwashes, dietary supplements, or antidepressants.
