I like it.

If I am correct, they sent me 4 night guards. I heated 3 of them, like the instructions instructed me to. One fits perfectly on my teeth. Important: you are instructed to heat the night guard in a boiling water, let it cool for a few secs, put it in your mouth and bite it down for a while. Then, you are done.

just right

love the different sizes. i have a smaller mouth and the ones in store never fit me right. the smallest guard fit me, but they can be cut to fit too.

Life saver! 2 per pack

This has been a life saver! My nerve pain from TMJ was from the top of my head into my neck and arm. Days with no sleep and loads of pain meds was debilitating! A friend recommended this product and now I'm pain free! If I feel tension in my jaw I just put this in and all is well :). This took a bit to get perfect, just repeat the process till you get the fit you like. I used a lighter to heat %26 smooth edges where it was thick. I only use on top teeth but plan on fitting the other in the pack to my bottom teeth and use them with my tooth whitener.
