What is the temporomandibular joint (TMJ)?
You may not have heard of it, but you use it hundreds of times every day. It is the Temporomandibular Joint (TMJ), immediately in front of the ear on each side of your head. The temporomandibular joint is also called the jaw joint. This joint allows your lower jaw to move, and it is one of the most frequently used of all joints of the body. When you bite down hard, you put force on the object between your teeth and on the joint. More force is applied (per square foot) to the joint surface than to whatever is between your teeth.
Temporomandibular Joint (TMJ) disorders is a common, painful condition affecting the jaw joints and surrounding muscles and ligaments. This and causes pain affecting the temporomandibular joint (TMJ) and/or the surrounding muscles which frequently gets better of its own accord. It is sometimes called facial arthromyalgia (FAM) or temporomandibular joint dysfunction (TMD).
Who gets Temporomandibular Joint Dysfunction?

- It may occur in people who have a tooth grinding or jaw clenching habit.

Is TMD a problem for you?
· Are you aware of grinding or clenching your teeth?
· Do you wake up with sore stiff muscles around your jaw?
· Do you have frequent headaches and neck pains?
· Does the pain get worse when you clench your teeth?
· Does your jaw click, pop or lock when you open your mouth?
· Is it difficult or painful to open your mouth, eat or yawn?
· Have you injured your neck, head or jaw?
· Do your teeth meet differently from time to time or do they no longer touch when you bite?
The more you have answered yes, the more likely it is that you have a TMJ disorder.
What Can Be Done for TMD?
Because TMJ symptoms often develop in the head and neck, ENT specialists are appropriately qualified to diagnose TMJ problems:
- Rest the muscles and joints by eating soft foods and use both sides at the same time
- Chew with your back teeth rather than biting with your front teeth
- Eat a soft diet
- Avoid oral habits that put a strain on jaw muscles and joints like chewing gum
- Avoid clenching or tensing
- Relax muscles with moist heat or cold (whichever feels better). Use for 10-20 minutes three or four times a day
- Exercise your jaw by opening and closing your mouth keeping the teeth aligned
- A soft plastic bite guard to cover the teeth may sometimes be made by your dentist to prevent you clenching too hard at night
- Ensure you get a good night’s sleep.
