Burning mouth syndrome

Medically reviewed by Last updated on Feb 22, 2023.


Burning mouth syndrome is the medical term for ongoing or recurring burning in the mouth without an obvious cause. You may feel this burning on your tongue, gums, lips, inside of your cheeks, roof of your mouth or large areas of your whole mouth. The feeling of burning can be severe, as if you injured your mouth with a very hot drink.

Burning mouth syndrome usually comes on suddenly, but it can develop slowly over time. Often the specific cause can't be found. Although that makes treatment more challenging, working closely with your health care team can help you reduce symptoms.


Symptoms of burning mouth syndrome may include:

Whatever pattern of mouth discomfort you have, burning mouth syndrome may last for months to years. In rare cases, symptoms may suddenly go away on their own or happen less often. Sometimes the burning feeling may be briefly relieved during eating or drinking.

Burning mouth syndrome usually doesn't cause any physical changes to your tongue or mouth that can be seen.

When to see a doctor

If you have discomfort, burning or soreness of your tongue, lips, gums or other areas of your mouth, see your health care provider or dentist. They may need to work together to help pinpoint a cause and come up with an effective treatment plan.


The cause of burning mouth syndrome may be primary or secondary.

Primary burning mouth syndrome

When the cause can't be found, the condition is called primary or idiopathic burning mouth syndrome. Some research suggests that primary burning mouth syndrome is related to problems with the nerves involved with taste and pain.

Secondary burning mouth syndrome

Sometimes burning mouth syndrome is caused by an underlying medical condition. In these cases, it's called secondary burning mouth syndrome.

Underlying problems that may be linked to secondary burning mouth syndrome include:

Treatment depends on whether you have primary or secondary burning mouth syndrome.

Primary burning mouth syndrome

There's no known cure for primary burning mouth syndrome. And there's no one sure way to treat it. Solid research on the most effective methods is lacking. Treatment depends on what symptoms you have and is aimed at controlling them. You may need to try several treatments before finding one or a combination that helps reduce your mouth discomfort. And it may take time for treatments to help manage symptoms.

Treatment options may include:

Secondary burning mouth syndrome

For secondary burning mouth syndrome, treatment depends on the underlying conditions that may be causing your mouth discomfort.

For example, treating an oral infection or taking supplements for a low vitamin level may relieve your discomfort. That's why it's important to try to find the cause. Once any underlying causes are treated, your burning mouth syndrome symptoms should get better.
