This is also known as Temporo-Mandibular Jaw (TMJ) pain. It is similar to dull toothache or wisdom tooth pain but is essentially muscular/myofascial pain. It is sometimes difficult to locate and there may be pain in the jaw joint and all the surrounding structures. In acute cases jaw opening may be limited.

How common is this type of pain?
One in four people at some time may have symptoms. Men and women are affected equally, although women tend to seek treatment more often.

What are its causes?
The commonest cause is tooth clenching or grinding and is often associated with stress and anxiety. Normally one is not aware of clenching their teeth. This is usually carried out while concentrating; at work, driving, doing the ironing etc.

There are day and night tooth grinders. Night grinding while sleeping is more destructive and difficult to deal with.

What causes the pain?
Increased muscle activity (the jaw muscles are the ones doing the extra work during tooth grinding/clenching). These muscles get tired and go into spasm, a cramp-like condition.

What can you do to help yourself?

1. If while concentrating or in a stressful situation, try and find out if your top and bottom teeth are touching. Normally teeth are apart, except while chewing and swallowing.
2. Eat evenly on both sides and avoid hard chewing and biting, chewing pens/pencils, finger nail biting etc.
3. In severe cases have a soft diet.
4. Avoid yawning with your mouth wide open.
5. A warm water bottle on the aching side will help.
6. If you have lost a few back teeth you might need them replaced to balance and support your bite properly.
7. In severe or chronic cases your dentist will construct an appliance for you to wear on your teeth.
