Are You A Grinder Or A Clencher?

Grinding & clenching are often signs of a jaw joint problem or TMJ

 

What does TMJ stand for?

The Temporomandibular joint is a hinge that connect you jaw to the temporal bones of your skull, which are in front of each ear. It let's you move your jaw up and down and side to side, so you can talkk, chew, and yawn.
 

So what problems can develop?

The problems range from -
  • A clicking jaw every time it is opened
  • lack of opening and movement
  • Pain in the jaw joint
  • headaches and pain around teeth and muscles
  • Grinding or clenching your teeth, which puts a lot of pressure on the joint
  • Arthritis in the joint
  • Stress, which can cause you to tighten facial and jaw muscles or clench the teeth

Why does it cause pain?
When it does not function properly, the TMJ can cause discomfort and severe pain. It can be temporary or last many years. It might affect one or both sides of your face. More women than men have it, and it’s most common among people between the ages of 20 and 40.

 

Common symptoms include:

  • Pain or tenderness in your face, jaw joint area, neck and shoulders, and in or around the ear when you chew, speak, or open your mouth wide
  • Problems when you try to open your mouth wide
  • Jaws that get “stuck” or “lock” in the open-or closed-mouth position
  • Clicking, popping, or grating sounds in the jaw joint when you open or close your mouth or chew. This may or may not be painful
  • A tired feeling in your face
  • Trouble chewing or a sudden uncomfortable bite - as if the upper and lower teeth are not fitting together properly
Pain may result from an uneven bite. As the jaws close they may not meet all of the teeth together which causes the jaw to slide which may also place the jaw out of alignment. A similar analogy being shoes with two different heel heights. In a short time the hips may start causing pain, or the lower back may cause pain or there may be pain in the legs due to the uneven alignment.
 

How do you know if you have a TMJ problem?

A simple home test that shows in approximately two thirds of people if there is a jaw joint problem, is to have 3 fingers straight and locked together then open your mouth as wide as possible and try to put the 3 fingers vertically between the top front teeth and bottom front teeth up to the second joint. If you are unable to comfortably do this then there is a definite problem with the jaw joint.
 

So what can be done if you suffer from this?

One of the most common cause of headaches is clenching or grinding, or as we like to call it “Bruxism”. As the teeth are misaligned and the bite is not even, a person can start grinding at night to eliminate the uneven bite. As a result the associated muscles go into overload and fatigue, often giving rise to headaches often in conjunction with pain in the lower jaw around the teeth. One method is to prevent the teeth from grinding, by either placing a barrier to grinding orproviding an even surface to close against. Using a bite splint at night does not allow the teeth to bite together so grinding is eliminated and usually after 1-2 weeks the headaches stop. If this is successful then a person can continue to wear a bite splint or elect to have the teeth aligned to achieve that even bite. If this does not help, then more advanced therapies may be needed such as Dysport (botox); a steroid wash of the jaw joint and very occasionally surgery. In the majority of cases, straightening the teeth to improve the bite is what gives the best long term results.

Dysport® is a protein taken from the bacteria Clostridium Botulinum. The protein was initially used for the treatment of motor disorders and various kinds of muscular spasms, including Cerebral Palsy. It was further developed to treat a wide variety of Neuro-muscular disorders, for which it is now licensed in 60 countries. In New Zealand, Dysport® has registration approval under the Medicines Act and was the first Botulinum Toxin Type A to be approved in this country.

HOW DOES IT WORK?

 

WHY IS DYSPORT® FOR TEETH GRINDING BETTER THAN OTHER PROCEDURES?

Many people with Bruxism will wear a mouth guard at night to protect their teeth, but some patients clench and grind during the day, wearing the guard during waking hours is not always practical. Dysport® is a great non invasive alternative for Bruxism. With this procedure, you will be able to chew normally and make facial expressions, but the involuntary grinding will be reduced or eliminated.

OTHER BENEFITS FOR USING DYSPORT® FOR JAW CLENCHING

Dysport® for Bruxism can also soften the appearance of the jaw line by reducing the size of the masseter muscle. Often patients who clench at night will have a more pronounced square jaw line. Dysport® causes the muscle to decrease in size, therefore slimming and contouring the jaw.
WHAT CAN DYSPORT® DO FOR YOU?
Dysport can also be used to reduce frown lines between your eyes and crows feet, and for the upper lip muscle to show less gum when you smile. Treatment takes less than 20 minutes and results can be seen within the first week.Dysport® is used to provide relief from headaches, jaw soreness and other side effects of Bruxism (teeth grinding and clenching) . Dysport® is placed into the masseter muscle (the main muscle for biting and chewing) . The muscle is temporarily weakened which prevents the muscle from clenching involuntarily while you sleep. This greatly reduces the painful side effects of Bruxism while saving your teeth.
