The NTI Tension Suppression System is a new FDA -approved method of headache and migraine prevention that is said to work by reducing night-time teeth clenching. This often intense nocturnal activity is purported to lead to a hyperactivity of the trigeminal nerve , often triggering typical migraine events. The objective of the NTI is to relax the muscles involved in clenching and mastication, thus diminishing the chances for migraines and tension headaches to develop.

The NTI is a small transparent plastic device which is worn over the two front teeth at night to prevent contact of the canines and molars. It is normally fitted by a dentist trained in the technique. It does not involve any drugs, shots, or surgery.

People with migraine pain suffer a lot. Medical examinations often show, however, that they're otherwise perfectly healthy. A recent medical study confirms that people who suffer migraine pain and chronic headache clench their jaws in a balanced, centered position. This causes extremely intense muscular contraction, but little strain on the jaw. Nighttime jaw clenching usually goes unnoticed - but it sets the stage for migraine pain and chronic headache pain.

The NTI Tension Suppression System (NTI-tss) is the only non-drug, non surgical device cleared by the FDA for prevention of medically diagnosed migraine pain and jaw disorders through the reduction of trigeminally innervated muscular activity.
