Customer ratings & reviews

Doing it right! Excellent customer service and a great product. I Highly recommended to anyone wanting to save $600 at the dentist or tired of spending $30-$50 every couple months on OTC sleep guards.

A Must-Buy! I tried other online companies and the fit was never right. This company gives you extra putty in the impression package to make sure the mold is correct. They give clear instructions for taking your impression. I took mine correctly on the second try. First try I hit my front teeth against the tray. Mailed it in and received my night guard about a week later. I sleep with it every night. My jaw pain and headaches are GONE! I'll be buying again in the future when this one wears out.

Very good, dependable service! Reliable, fast and helpful with a great product! Would recommend!

Finally an affordable option! This is now my favorite company! Process was easy and mouth guard fits like a glove. I highly recommend.

Great night guard! I used to buy the bulky boil & bite guards because I didn't want to pay the price but I always ground through them and ended up spending more money than if I would have just got a custom one! Fantastic fit and high quality. Couldn't be happier with my purchase!

Worth it!! Had my dentist make me a guard and it was so bulky and uncomfortable I never wore it. Tried to get a refund but umm no. Found this company online and for $130 this was far less expensive than my dentist. Glad I did it! Fast, friendly service and my mouth guard fits like a dream. Thank you Sentinel team!

This guard is great! Fit is spot on. I highly recommend *****

A++++ fast shipping. Excellent correspondence & solid product. Thumbs up!!

Very happy! This is a great service for people like me who are on a fixed income and can't afford the dental office price. I'm elderly and I was nervous about taking my teeth impression but I did it and it was easier than I thought. I appreciate that they keep my impression on file for future orders. Good company with great staff!

I’m on my third nightguard right now and I could never go back! The nightguard fits perfectly and it is so comfortable. I can completely tell the difference when I don’t wear it. I absolutely love my nightguard! The service of Sentinel is great too! I had a crack in my guard, and they sent me one for free! I would highly recommend this! The only downside is that mine has calcium build up and has yellowed. I’d like to know how to avoid that.
