A non-drug, FDA-cleared approach that reduces trigeminal system sensitivity—helping prevent migraines before they start.

Why Do Migraines Keep Coming Back?

Migraines are not just random events—they are often driven by a sensitized nerve system. When the trigeminal system becomes more reactive, even small triggers can lead to a migraine. The key isn’t just treating the migraine—it’s lowering the system’s sensitivity before it starts.

A Different and More Effective Approach to Migraine Prevention

Most migraine treatments work after the process has already started.

The NTI MigraineGuard modulates and reduces upstream nociceptive input into the trigeminal system—helping lower sensitization and reduce the likelihood of migraine activation.

In simple terms:

• Reduces stress on the trigeminal nerve system
• Helps make your system less reactive to triggers
• Lowers the chance a migraine gets started

Clinically Grounded. Mechanistically Sound.

This approach targets upstream drivers of trigeminal sensitization, including afferent input associated with craniofacial and masticatory activity.

By reducing nociceptive input into the trigeminal system:

• Central sensitization is reduced
• The likelihood of engaging the trigeminal–autonomic reflex is lowered
• Downstream amplification pathways (including CGRP-related signaling) are less likely to be activated

FDA-cleared for migraine prevention and now available for OTC use.

Researchers had once believed that headache pain upon waking was a sign of “medication rebound”, or residual migraine pain, or due to the sufferer’s anxiety. 

New research has confirmed that “morning headache” is an integral part of migraine disease.

 Migraine is a dysfunction of the Trigeminal cranial nerve, primarily the sensory center (or “nucleus”).  The Trigeminal Sensory Nucleus can become dysfunctional, or "sensitized" following excessive input of negative information, or “nociception”, resulting in a release of the neuropeptide CGRP that is responsible for migraine pain. 

 During sleep, in most every chronic migraine sufferer, the “motor” division of the Trigeminal nerve causes intense pathologic hyperactivity to the muscles that cover the temples, causing a tremendous squeezing and clenching of the jaws, strain and load to the jaw joint, compaction of the teeth into their sockers, resulting in a bombardment of nociception (negative information) back to the sensory nucleus, resulting in waking with varying degrees of headache, to full-blown migraine. 

The NTI MigraineGuard (NTI = Nociceptive Trigeminal Inhibition) is an intra-oral, custom-fabricated medical device that specifically prevents the Trigeminal motor hyperactivity, thereby minimizing any nociception, resulting in a profound reduction in the disability caused by migraine pain, and a significant improvement in the quality of life for the chronic migraine sufferer. 

Since 2001, the NTI MigraineGuard has only been available by prescription, provided by a trained dentist (for example, Glidewell Lab offers the NTI to their prescribing dentists). While visiting a dental professional is the, by far, preferable method of being treated with an NTI MigraineGuard, the FDA has now cleared MigrainePrevention.com to provide the NTI MigraineGuard directly to the sufferer.
