Burning Mouth Syndrome (BMS) is a hot feeling or sensation which can affect your tongue, lips, palate or areas all over your mouth. BMS is sometimes called ‘glossodynia'.
You get the feeling when there are changes in the way the nerves in your mouth send messages to your brain - for example, about taste and temperature. When your brain doesn't understand these messages properly it can cause the feeling of pain or burning.
Although some parts of your mouth may feel like they are burning, they will not be hot to the touch. You might not be able to see any soreness or redness in the areas that are hurting.
BMS is sometimes called a ‘neuropathic pain', as it happens when there is damage to the nerves.
It's hard to say. No one knows exactly what causes BMS. However, some possible causes include:
As with any long-term condition, dealing with constant day-to-day pain can get you down. Often this can lead to depression. If a cause for your BMS cannot be found, your GP may prescribe a low-dose anti-depressant, or refer you for Cognitive Behavioural Therapy, to help you to deal with this.
Anyone can have BMS, but it is more common in middle-aged or older women during the menopause (‘change of life').
You may have a moderate to severe burning feeling on your tongue, palate, lips, gums or inside your cheek.
For some people the feeling begins in the morning and builds up to a peak by the evening, often easing by the night-time. Some people have the burning feeling all the time. For others, the pain comes and goes. Other symptoms may include numbness or tingling of your mouth or tongue, a bitter or metallic taste, or a dry or sore mouth.
People often describe BMS as feeling like you have scalded your mouth with hot food or drink.
Your dentist will examine your mouth thoroughly to try to find the cause of the problem. They will also look at your medical history and may refer you to your doctor for ‘investigations'. These could be blood tests or swabs, to see if there are any infections, nutritional deficiencies or other medical conditions.
You may need to have allergy testing done by a specialist dermatologist. Your doctor can refer you for this if needed.
You may also need blood tests to see if you have a deficiency or disorder such as thyroid problems or diabetes.
Treatments for BMS can vary depending on the causes.
If BMS has been brought on by poor diet, then your dentist can recommend supplements for you. If needed, your dentist can also adjust or replace irritating dentures or prescribe you medication for a fungal infection in your mouth.
Some doctors may prescribe a course of counselling and low-dose anti-depressants. This is because BMS can 'wear down' some people and cause depression because they are having a daily battle with the pain. Doctors can also change your medication if your BMS has been caused by ‘dry mouth' (a side effect of some medications).
Other therapies can include relaxation, yoga, meditation and hypnotherapy, as they have been found to help some people cope with anxiety.
You can help to ease the symptoms yourself at home by:
First of all, see your dentist for a check-up. They will then be able to find out if the cause is a dental one, such as your denture or ‘dry mouth'. If it is, your dentist can check the fit of your dentures (if you wear them) and can also see whether you are allergic to the material they are made from. They can also recommend products to ease dry mouth or get rid of any fungal infection.
If your dentist cannot find a dental cause, they may suggest that you visit your GP or refer you to a specialist. You can then have a blood test to try and find the cause of your BMS.
As no one knows the exact causes of BMS, it is hard to plan a correct course of treatment. Therefore, BMS is a long-term condition which could affect you for months, years, or perhaps the rest of your life.
If you find ways of coping with and limiting the pain, and have treatments or therapies recommended by your doctor, there's no reason you cannot do the things you did before.
It is important to keep a record of how your symptoms are affected by the different types of treatment. Your dentist or GP will then have a better idea of what treatment is best for you - after all, everybody is different.
There are some medical conditions which might cause BMS. They are:
In some cases, BMS may have more than one cause.
