Causes
The possible causes of burning mouth syndrome are many and complex. Each of the following possible causes applies to only a small portion of all people who complain of a burning mouth. Many people have multiple causes. Identifying all of the causes is important so that your doctor can develop a treatment plan tailored for you. Possible causes include:- Dry mouth (xerostomia). This condition can be related to use of various medications. It can also occur with aging or Sjogren's syndrome, an autoimmune disease that causes both dry mouth and dry eyes.
- Other oral conditions. Oral yeast infection (thrush) is a common cause of a burning mouth. Geographic tongue, a condition that causes a dry mouth and a sore, patchy tongue, also may be associated with burning mouth syndrome.
- Psychological factors. Emotional disorders, such as anxiety and depression, are often associated with burning mouth syndrome.
- Nutritional deficiencies. Being deficient in nutrients, such as iron, zinc, folate (vitamin B-9), thiamin (vitamin B-1), riboflavin (vitamin B-2), pyridoxine (vitamin B-6) and cobalamin (vitamin B-12), may affect your oral tissues and cause a burning mouth.
- Irritating dentures. Dentures may place stress on some of the muscles and tissues of your mouth. The materials used in dentures also may irritate the tissues in your mouth.
- Nerve disturbance or damage (neuropathy). Damage to nerves that control taste and pain in the tongue may also result in a burning mouth.
- Allergies. The mouth burning may be due to allergies or reactions to foods, food flavorings, other food additives, fragrances, dyes or other substances.
- Reflux of stomach acid. The bitter-tasting fluid that enters your mouth from your upper gastrointestinal tract may cause irritation and pain.
- Certain medications. Angiotensin-converting enzyme (ACE) inhibitors, used to treat high blood pressure, may cause side effects that include a burning mouth.
- Endocrine disorders. Your oral tissues may react to high blood sugar levels that occur with conditions such as diabetes and underactive thyroid (hypothyroidism).
- Hormonal imbalances. Burning mouth syndrome occurs most commonly among postmenopausal women, although it affects many other people as well. Changes in hormone levels may affect the composition of your saliva.
- Excessive irritation. Irritation of the oral tissues may result from excessive brushing of your tongue, overuse of mouthwashes or consuming too many acidic drinks.
Treatment of burning mouth syndrome is highly individualized and depends on your particular signs and symptoms and on the underlying cause or causes, if they can be identified. Most people with burning mouth syndrome can control their symptoms through tailored treatment plans.
Burning mouth syndrome can be painful and frustrating. The good news is that it's a treatable condition. Although it may take time, with the help of a team of health professionals, you can usually find a treatment plan that's right for you.
In the short term, you may gain some relief by avoiding irritating substances, such as alcohol-based mouthwashes, cinnamon or mint products, and cigarette smoke. Chewing on ice chips or sugar-free gum also may help.
