Burning mouth syndrome most often affects women after menopause. Learn the symptoms, which causes to rule out, and treatments with evidence behind them.

Burning mouth syndrome is a burning, scalding or tingling feeling in the mouth, often the tongue, with no visible cause. It most often affects women after menopause, and may affect up to a third of postmenopausal women. Treatable causes, such as deficiencies, thrush and dry mouth, are ruled out first. Treatments include topical clonazepam and CBT.
How strong is the evidence? Moderate for the link with postmenopausal women; limited for treatments.
The mouth usually looks normal on examination.
Burning mouth syndrome occurs most often in postmenopausal women. Researchers suggest changes in sex hormones may predispose women to it, possibly through effects on the nerves and tissues of the mouth. Menopause-related dry mouth and changes to the oral lining may add to it. See gum problems.
Anxiety, depression and sleep problems are common in people with burning mouth syndrome, and can make pain feel worse. See anxiety and low mood.
The BMJ review notes that symptoms of burning mouth can also be caused by:
| Cause | Clues |
|---|---|
| Oral thrush | White patches, redness, especially with dentures or inhaled steroids |
| Vitamin or iron deficiency | Low B12, folate or iron; a sore, smooth tongue |
| Dry mouth | Medicines, Sjögren’s syndrome, dehydration |
| Allergies or irritants | Toothpaste, mouthwash, foods, dental materials |
| Ill-fitting dentures | Sore areas under dentures |
| Acid reflux | Heartburn, sour taste |
| Diabetes or thyroid problems | Other symptoms, such as thirst or tiredness |
| Some medicines | Such as some blood pressure medicines |
"Primary" burning mouth syndrome is diagnosed only when these causes have been ruled out. See perimenopause or something else.
A dentist or doctor will examine your mouth, check dentures, and ask about medicines, dry mouth, reflux and diet. Blood tests may include a blood count, iron, vitamin B12, folate, blood sugar and thyroid function. They may take a swab for thrush, or suggest allergy testing.
For two weeks, note:
This helps identify triggers, and gives your dentist or doctor useful information.
Burning mouth can be frustrating, especially when tests come back normal. Knowing it’s a recognized condition, and not a sign of something dangerous, can reduce worry. Pain often feels worse when stressed or tired, so looking after sleep and stress is part of treatment. Support from an oral medicine specialist or pain team can help if symptoms persist.
Book an appointment with a dentist or doctor if burning lasts more than a couple of weeks.
See a dentist or doctor promptly if you have:
- A mouth ulcer or sore that doesn’t heal within three weeks
- A white or red patch, or a lump, in the mouth
- Difficulty swallowing, or unexplained weight loss
- Numbness of the tongue or lips that’s new or spreading
Gum problems · Dry eyes · Anxiety · Low mood
It’s most common in postmenopausal women, and hormone changes may play a role. Other causes should be ruled out first.
The BMJ review notes complete remission happens in only a small percentage of people, while up to 30% improve with or without treatment.
It isn’t known, as there are few studies.
Cool water, avoiding spicy and acidic foods, a mild toothpaste and sugar-free gum can all help.
Either is a good starting point. A dentist can check for dental and denture causes, and a doctor can arrange blood tests. Some people are referred to an oral medicine specialist.
