Customer ratings & reviews

My dentist had been recommending a night guard for my teeth grinding but I couldn't spend the money. Finally it got to the point where my teeth were wearing down, jaw was aching so bad, and I had headaches almost every morning. I found Sentinel online and the price is inexpensive compared to the dentist. I was sent a kit with the putty mixture and an extra set of putty in case needed. I took the impressions. FYI they make you take an upper and lower to check the bite before shipment. It took about a week and a half after I sent the impressions off to receive my night guard. It took me a few nights to get used to it but now I can't sleep without it! Wish I could give more than 5 stars. Excellent experience. Love that this is available to us as an affordable option.

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! *****

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.
