Burning Mouth Syndrome (BMS)
Burning mouth syndrome (BMS) is a painful, frustrating condition often described as a scalding sensation in the tongue, lips, palate, or throughout the mouth. Although BMS can affect anyone, it occurs most commonly in middle-aged or older women.
BMS often occurs with a range of medical and dental conditions, from nutritional deficiencies and menopause to dry mouth and allergies. But their connection is unclear, and the exact cause of burning mouth syndrome cannot always be identified with certainty.
Signs and Symptoms
Moderate to severe burning in the mouth is the main symptom of BMS and can persist for months or years. For many people, the burning sensation begins in late morning, builds to a peak by evening, and often subsides at night. Some feel constant pain; for others, pain comes and goes. Anxiety and depression are common in people with burning mouth syndrome and may result from their chronic pain.
Other symptoms of BMS include:
- tingling or numbness on the tip of the tongue or in the mouth
- bitter or metallic changes in taste
- dry or sore mouth.
There are a number of possible causes of burning mouth syndrome, including:
- damage to nerves that control pain and taste
- hormonal changes
- dry mouth, which can be caused by many medicines and disorders such as Sjögren's syndrome or diabetes
- nutritional deficiencies
- oral candidiasis, a fungal infection in the mouth
- acid reflux
- poorly-fitting dentures or allergies to denture materials
- anxiety and depression.
In some people, burning mouth syndrome may have more than one cause. But for many, the exact cause of their symptoms cannot be found.
