Burning Mouth Syndrome: Symptoms, Causes and How It’s Managed

A burning, scalded or tingling feeling in your mouth is hard to ignore, and it is even harder when your mouth looks completely normal. If this sounds familiar, you may be wondering about burning mouth syndrome, what causes it and what can be done.

This guide explains the symptoms, the possible causes, how it is assessed and how it is managed. It also covers when to see a dentist or GP.

This article is general information only. It is not a diagnosis. Burning in the mouth has many possible causes, and only an examination can work out which applies to you.

What is Burning Mouth Syndrome?

Burning mouth syndrome is a burning, scalding or tingling feeling in the mouth, often with no visible sore or change. It usually affects the tongue, and it can also affect the lips, the roof of the mouth, the gums or the whole mouth.

The affected areas may feel hot, but they are not hot to the touch. The cause is not fully understood, and it is thought to involve how the nerves that control pain and taste work (National Institute of Dental and Craniofacial Research, “Burning Mouth Syndrome”, 2026).

Burning Mouth Syndrome Symptoms

• A burning, scalding or tingling feeling, often described as if you have scalded your mouth.
• A sensation that is worse at certain times, for example, building up through the day.
• Numbness or tingling in the tongue or mouth.
• A dry or sore mouth, or a feeling of thirst.
• A bitter or metallic taste, or changes in taste.

For some patients, the feeling is constant, and for others it comes and goes. It can last for months or longer. Our article on what your tongue says about oral health explains other changes to look out for.

What Causes Burning Mouth Syndrome?

When no other cause can be found, the condition is usually called burning mouth syndrome, and its cause is not well understood. In other patients, a burning feeling has an underlying cause that can be found and treated. Possible causes include:

• Dry mouth.
• A mouth infection, such as a yeast infection (oral thrush).
• Dentures that fit poorly or rub.
• Reactions to foods, drinks or oral care products.
• Acid reflux.
• Hormonal changes. It is reported more often in women around and after menopause.
• Nutritional or general health factors. Your doctor can look into these.
• Habits such as clenching or pushing the tongue against the teeth.
• Stress and anxiety, which can make symptoms worse.

Your dentist or doctor will usually look for these causes first before suggesting burning mouth syndrome.

Is Burning Mouth Syndrome Dangerous?

Burning mouth syndrome itself does not usually damage the mouth, but it can be uncomfortable, and it can affect eating, sleep and mood.

The bigger concern is that a burning mouth can sometimes be caused by something else that needs treatment. That is why it is worth having it checked and not assuming it is harmless.

How Burning Mouth Syndrome is Assessed

There is no single test. Your dentist or doctor will usually:

• Ask about your symptoms, when they started, what makes them better or worse, and your medical history.
• Examine your mouth, tongue, teeth and gums, and any dentures.
• Look for dry mouth, infection or irritation.
• Suggest seeing your GP for further checks if no dental cause is found.

The NIDCR notes that burning mouth syndrome can be difficult to diagnose, and that other conditions are ruled out first.

How Burning Mouth Syndrome is Managed

There is no single treatment that works for everyone, and results vary. Management usually starts with finding and dealing with any cause. This could mean:

• Adjusting or replacing a denture that rubs.
• Looking at dry mouth and ways to manage it.
• Treating an infection if one is found.
• Reviewing the oral care products you use.

If no cause is found, a GP or dentist may discuss treatment options with you. They may also suggest strategies for reducing the burning and ways to manage stress, since it can make symptoms worse.

Things That May Help Day to Day

• Sip water through the day to keep your mouth moist.
• Avoid very hot, spicy and acidic foods and drinks if they make it worse.
• Limit alcohol, and avoid tobacco.
• Ask your dentist or pharmacist about oral care products that are gentle on the mouth.
• Keep a short note of what makes your symptoms better or worse, and bring it to your appointment.

These steps may ease discomfort for some patients, but they cannot be guaranteed to make the burning go away.

When to See a Dentist or GP

See your dentist or GP if:

• You have a burning or tingling feeling that lasts more than a couple of weeks.
• You notice sores, white or red patches, a lump or swelling.
• You have a fever or feel generally unwell.
• You have trouble swallowing, or taste changes that don’t settle.
• The burning is affecting your eating or sleep.

If you have sudden numbness or weakness in your face, trouble speaking, or severe symptoms, call 000 or go to your nearest hospital emergency department.

Burning Mouth Syndrome FAQs

Can burning mouth syndrome go away?

For some patients it eases or goes away over time, and for others it continues. It varies, and your dentist or doctor can talk through what to expect in your case.

Is it caused by anxiety?

Not on its own. Stress and anxiety may make symptoms worse, and living with the condition can affect mood, but burning mouth syndrome is not “all in the mind”. Your dentist or doctor will look at the whole picture.

Can dentures cause a burning mouth?

They can, if they fit poorly, rub or aren’t cleaned well. Tell your dentist, who can check the fit and the lining of your mouth.

Why does my mouth look normal if it burns?

In burning mouth syndrome, the mouth often looks normal because the problem is thought to involve how the nerves work, not visible damage. A normal appearance doesn’t mean the discomfort isn’t real.
