Customer ratings & reviews

Fit was way better than I expected. It came well packaged with a retainer case. My mouth is large so I was worried about the fit but it's quite perfect. Great value for the money.

My teeth weren't too bad but some yellowing from coffee stains. I'm a former dental assistant and know that getting the gel on your gums can be irritating so be careful. The instructions say to have it on for 2-4 hours. I kept it on for about 45 minutes each session and it takes about 5 days to see optimal results. Only 1/2 of the one tube out of 3 were used so plenty of gel leftover for future whitening. Highly recommend!!

Half the cost then my dentist is selling for the exact same product and same results.

This night guard company was recommended by my dentist. This product works very well and it relieved my jaw pain very quickly. I use it almost every night, overnight, and sometimes during the day. I can feel it when I don't use it! Results are great and the impression kit was straightforward. Turnaround time was quick. I highly recommend!!

Impressions were easy to take. The instructions were easy to follow and that was the part I was most nervous about. I have a bad gag reflex and worried I couldn't handle anything in my mouth. This was not the case at all. Easy, easy. I received my guards and I can tell this company cares. They were beautifully crafted and fit like a glove. I now go to sleep not worrying about biting my cheeks. The relief I feel is well worth the investment.

I'm impressed with their professionalism and would highly recommend their services to anyone looking for help with a mouth guard for teeth grinding.

Love that I didn't have to go to my dentist to get these, super impressed with how well made. 5 stars!

I've had other nightguards before, but this is probably my favorite. t fits like a glove. It was easy to take the impression of my teeth, and I appreciate that they included an extra putty pock in case I messed up! I'm a picky person when it comes to anything I have to wear in my mouth so I'm pretty impressed with this nightguard.

The communication was excellent, and the turnaround time was very fast. I would highly recommend this company for anyone looking for a reliable night guard provider.

Love Sentinel Mouthguard products. This one has protected my teeth longer than the one my dentist made me. -CK
