What Is Burning Mouth Syndrome?When Your Tongue Feels Scalded

It started as a tingle on the tip of your tongue, like you’d sipped coffee too hot. That was weeks ago. Now it’s most days, a scalded, sandpapery feeling that eases when you eat and returns by afternoon. Your dentist found nothing wrong. Your tongue looks normal.

What it feels like

The NIDCR¹ says the pain typically affects the tip and sides of the tongue, the roof of the mouth and the lips, and can come with a dry mouth and altered taste, sometimes metallic. The NHS² leaflet describes moderate to severe burning that may last for months or years, with tingling, taste changes and dryness.

Cleveland Clinic³ says symptoms can vary through the day.

Who gets it, and why

The NHS² leaflet says it often affects women, particularly after menopause, and that up to one in three older women experience it. Cleveland Clinic³ says changes in estrogen levels during menopause can affect your mouth.

The cause isn’t always clear. Cleveland Clinic³ separates two types. Primary BMS is burning with no clear reason, likely involving nerve damage that affects taste and pain control, and possibly stress and hormonal changes. Secondary BMS is caused by another problem, and treating that may resolve it. The NIDCR¹ also says experts attribute BMS to damage to the nerves in the mouth that control pain and taste.

The conditions on the lists to rule out:

• Dry mouth, from medicines or Sjögren’s disease, per the NIDCR¹. See waking up with a dry mouth.
• Oral infections, including fungal infections, per the NHS² leaflet and the NIDCR¹. See a white tongue.
• Acid reflux. See heartburn and GERD.
• Nutritional deficiencies, per all three sources, along with diabetes (the NHS² leaflet and Cleveland Clinic³).
• Denture problems, per the NHS² leaflet.
• Allergies and teeth grinding, per Cleveland Clinic³. See grinding your teeth.
• Anxiety and stress, per all three. See mood changes around menopause.
• Blood pressure medicines, per the NIDCR¹.

How it’s diagnosed

Start with your dentist. Cleveland Clinic³ says they examine your mouth and check for contributing factors like teeth grinding, and specialists may order allergy tests, blood work, swabs or other tests. The NHS² leaflet says doctors take a history, do a thorough oral examination and order blood tests to check for infections, deficiencies and related conditions such as diabetes. The NIDCR¹ says your dentist may refer you to oral medicine, oral surgery, oral pathology or ENT specialists.

What helps

Cleveland Clinic³ says treating a secondary cause may resolve it, and that for primary BMS the options include mouth rinses with mild numbing effects, pain relievers, saliva substitutes, antianxiety medicines, antidepressants and cognitive behavioral therapy. The NHS² leaflet adds adjusting dentures and supplements for deficiencies, and says low-dose antidepressants are used. It also says symptoms often improve after reassurance that there’s no serious disease. The NIDCR¹ notes that responses vary, so treatment often takes experimentation.

For comfort in the meantime, the NIDCR¹ and Cleveland Clinic³ both suggest cold drinks and sugarless gum, and the NIDCR adds ice chips. Avoid tobacco, alcohol, hot and spicy foods, and acidic products such as citrus, the NIDCR says, along with alcohol-containing mouthwash. The NHS² leaflet says to stay hydrated.

The play

Try this: a mouth-burn log

For two weeks, write when the burning is worst, what you ate and drank, and any new products, including toothpaste and mouthwash.

Note anything that eases it, like eating or a cold drink.

List every medicine and supplement you take. Bring the log to your dentist.

When to get checked

Don’t wait if

1. Urgent

   If your mouth burns along with swelling, blisters, or trouble swallowing or breathing, get care right away.

Cleveland Clinic³ says to contact a provider if the burning lasts longer than a few days, worsens, or causes swelling or blisters. The NIDCR¹ says to start with your dentist.

Book an appointment if any of these fit:

• Burning has lasted more than a few days
• It’s getting worse, or it’s there most days
• You also have a dry mouth, a metallic taste or white patches
• You wear dentures that rub or don’t fit
• You take medicines that may be drying out your mouth
• You’re past menopause and it started around then

The mouth looks fine and still hurts. That’s a recognized condition with a name, and a starting point is your dentist’s chair.
