An Nti only covers the upper (or lower) front teeth. So it feels like there is less in your mouth.

Also because of it's barely noticeable size it can be worn during the day if needed.

An NTI is a new type of Nightguard/dayguard.

We have had great success in treating chronic headache and certain types of migranes.
