Frequently Asked Questions

Consult Your Doctor

Only a physician can diagnose your headache. Patients without a diagnosis and patients having new or “worst ever” headaches should consult their physician. All NTI patients must be diagnosed by a medical doctor to have tension type or migraine headaches.

All forms of organic disease must be ruled out prior to NTI treatment.

The NTI System is not effective for everyone.

How do I know that NTI is safe?

The FDA approved both the safety and effectiveness of the NTI-tss in June 2001. Extensive testing was required before the FDA gave its approval.

I have migraines with visual effects. Can I be helped?

Yes. The NTI-tss protocols are effective for most types of migraines and tension type headaches, including migraine with aura (visual effects).

I've tried night guards before, why should the NTI work any better?

The NTI-tss is unlike any other night guard or oral device, hence the U.S. and international patents. Other devices are bigger, bulkier and can actually increase clenching and facial tension. The NTI-tss is small, comfortable and reduces clenching of the powerful migraine muscle.

My current medicines control most of my headaches, why should I try the NTI?

The NTI-tss is for patients who want to prevent the onset of headaches without the use of drugs.

I have crowns on my front teeth. Does that mean the NTI can't help me?

No, crowns and veneers won’t interfere with the NTI system. There are some situations when artificial teeth (like implants) are a problem. Our exam can determine if you are a good candidate for NTI-tss treatment.

My doctor thinks my headaches are related to TMJ. Am I out of luck?

Not at all. The NTI can be effective for TMJ problems. In fact, the FDA approved the NTI-tss for TMJ (the jaw joint) several years before it received migraine approval.

I wear dentures. Can the NTI help me?

Unfortunately not. The NTI-tss protocols depend on natural front teeth to control the intense clenching common to nearly all headache and migraine patients. Hopefully, this will change someday.
