NTI night guard

This mouth guard, which is short for Nociceptive Trigeminal Inhibition Tension [Tension Relief headaches, teeth clenching relief Abingdon]  Suppression System, or NTI-tss, fits over a person's two front teeth. Users wear the guard during sleep. The device prevents teeth-clenching, which, in turn helps prevent migraines and tension headaches.

It is well-known that persistent tooth clenching or grinding will wear down teeth and cause them to crack, chip and break. Uneven edges of front teeth are the most noticeable signs, but worn back teeth with broken fillings and notches at the gum line are just as common.

An interesting fact is that most people are completely unaware they grind their teeth. Some people with seriously worn teeth insist that they don’t grind. The fact is that most clenching and grinding, called bruxism, occurs at night during sleep. That is why most bruxers are unaware of their habit.

In addition to the obvious changes in the appearance of the teeth, this habit results in other signs and symptoms. The facial muscles around the jaw and the sides of the skull can become enlarged due to hyperactivity. During bruxing, these muscles work very hard.

As with any muscle, overuse can cause tenderness, spasms, and pain. When these muscles become spastic, they can trigger headaches – all kinds of headaches.

It’s amazing how many people live with headaches. Some just accept it as normal. People wake up with headaches every day and don’t even think twice. Some blame their headaches on sinus problems, stress, allergies, or other various issues. The truth is that diagnosis for specific headache conditions has been elusive, and preventive treatment almost non-existent.

A recent study has shown what many dentists have long known: bruxing causes headaches. And if bruxing can be reduced or eliminated, the headaches go away. The traditional treatment for bruxism has been a night guard – a plastic appliance worn in the mouth similar to an athletic mouth protector. The night guard covers the teeth of one arch, and with the night guard in place, the patient bites on the plastic so there is no tooth-to-tooth contact while biting. Any night guard will protect the teeth from wear, but a new design has been shown to dramatically reduce muscle activity. This design is called an NTI appliance.

In a recent FDA study of migraine sufferers, the NTI reduced migraines by 77% in 82% of the patients. There were no side-effects and no new pain problems. Nausea associated with the migraines was reduced 78%, and light and sound sensitivity was reduced over 68%.

It is our experience that the NTI is most effective in treating any headache condition that occurs regularly, particularly those headaches that are present upon waking.
