EXCELLENT QUALITY AND GREAT ALTERNATIVE TO THE DENTIST!!

Much less expensive than the dentist yet seems to be the same quality. Headaches and jaw pain have gone away! Easy set up.They provide you with simple instructions. I recommend!

This mouth guard is amazing. I grind my teeth very heavily during both the day and night though I think I'm clenching more during the day. Brought this into my dentist appointment assuming he was going to tell me it was no good and to buy his $800 mouth guard from his office. He looked at it both in and out of my mouth and said it's a "very well made guard." I've tried many store brand mouth guards and bit right through those within months. Sentinel will be my go-to brand from now on.

Great mouth guard! Extremely sturdy and high end.

This is it! Best night guard and great customer service!! A high quality custom made night guard for this price? This is fantastic and just what I've been looking for. I have only used it a few nights but this is awesome so far. If this works well and lasts, you have a customer for life!

Customer service is outstanding! Suzanne was there to answer all of my questions beforehand. Very happy with my purchase. Will recommend! *****

This was a great purchase. My teeth had finally gotten to the point of no return and I had to do something. This fits perfectly. Easy instruction and feels Great!!!!!

The quality is unmistakable as is the comfort. This guard is the perfect fit and just like the one I ordered from my dentist years ago. This is the real deal. I highly recommend -JL

This night guard lasted me over 6 years and I just ordered my 2nd one. High quality and well worth it. Beats the heck out of going to the dentist.

Fabulous product! Should have done this a long time ago. My jaw pain has gotten so much better. After the first night I noticed a huge difference. During the day, I don't experience the popping and clicking like I used to. I recommend this.
