What does clenching my teeth have to do with these problems?

Patients who suffer from Bruxism could be clenching and grinding their teeth when sleeping at night. The high-intensity contractions of these powerful muscles become painful and the forces generated cause pain to the surrounding tissues, joints, and other muscles. By reducing the intensity of the clenching, you are effectively minimising the source of the pain.


Has this treatment been tested?

The NTI-tss® device has been used successfully with thousands of patients in the United States and many other countries. It has received marketing allowance from the FDA and complies with all requirements as an approved dental device.


What can we do to help?

In one dental visit, we can create a custom-made NTI device. The tiny, clear-plastic device fits over your top two front teeth. You only wear the NTI-tss device while you are asleep. It makes clenching virtually impossible. In a few days or weeks, your clenching reflex is suppressed. Morning headache pain, neck pain, sore jaw, and other related pain associated with involuntary intense clenching usually begins to resolve and disappear. It will also help to reduce tooth wear caused by teeth grinding.


Is there a difference between the NTI device and the traditional dental night guard device or TMJ splint?

NTI device Yes. Traditional flat-plane splints and night guard devices provide a surface for you to “bite down on.” New studies show, however, that these devices can actually increase the intensity of your clenching reflex, often to over 104% of your normal bite. High-intensity clenching has recently been found to be the real cause of the problem. With the advent of the revolutionary NTI device, we can begin to solve the real problem: actually preventing your back teeth from clenching intensely and coming into contact with each other. Stop intense clenching, stop the source of the pain.


When can I expect relief?

Many patients report significant relief overnight, others usually within a month.


Can clenching my teeth really cause problems?

Yes! Clenching your teeth while you are asleep and during the day is the result of some of the strongest muscles in your body tensing up (up to 6 to 20 times more intensely than non-sufferers), which can cause tension headaches and even damage surrounding joints, teeth, and other muscles.book dental appointment
