What is Burning Mouth Syndrome?
Burning mouth syndrome is the medical term for ongoing (chronic) or recurrent burning in the mouth without an obvious cause.
This discomfort may affect the tongue, gums, lips, inside of your cheeks, roof of your mouth (palate) or widespread areas of your whole mouth. The burning sensation can be severe, as if you scalded your mouth.
Burning mouth syndrome usually appears suddenly, but it can develop gradually over time.
Unfortunately, the specific cause often can't be determined. Although that makes treatment more challenging, working closely with your health care team can help you reduce symptoms.
Symptoms
Symptoms of burning mouth syndrome may include:
- A burning or scalding sensation that most commonly affects your tongue, but may also affect your lips, gums, palate, throat or whole mouth
- A sensation of dry mouth with increased thirst
- Taste changes in your mouth, such as a bitter or metallic taste
- Loss of taste
- Tingling, stinging or numbness in your mouth
The discomfort from burning mouth syndrome typically has several different patterns. It may:
- Occur every day, with little discomfort when you wake, but become worse as the day progresses
- Start as soon as you wake up and last all day
- Come and go
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 become less frequent. Some sensations may be temporarily relieved during eating or drinking.
Burning mouth syndrome usually doesn't cause any noticeable physical changes to your tongue or mouth.
Causes
The cause of burning mouth syndrome can be classified as either primary or secondary.
Primary burning mouth syndrome
When no clinical or lab abnormalities can be identified, the condition is called primary or idiopathic burning mouth syndrome.
Some research suggests that primary burning mouth syndrome is related to problems with taste and sensory nerves of the peripheral or central nervous system.
Secondary burning mouth syndrome
Sometimes burning mouth syndrome is caused by an underlying medical condition. Underlying problems that may be linked to secondary burning mouth syndrome include:
- Dry mouth
- Fungal infection of the mouth or a geographic tongue
- Allergies or reactions to food
- Reflux of stomach acid (gastroesophageal reflux disease)
- Certain medications
- Oral habits, such as tongue thrusting, biting the tip of the tongue and teeth grinding (bruxism)
- Endocrine disorders
- Excessive mouth irritation
- Psychological factors, such as anxiety, depression or stress
