Customer ratings & reviews

Quality retainers, great customer service and very affordable. They give extra putty if you need it. Great value for the money!

I highly recommend this mouth guard company. Their customer support is wonderful. I messed up my dental impression twice and they were very thorough in explaining where I went wrong. On the 3rd attempt I got it right. My night guard was a little too tight initially so I sent it in for an adjustment. Turnaround time was very fast. Overall, I'm extremely pleased with my night guard and the experience as a whole!

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.

I have a small mouth and needed small tray sizes sent out. Sentinel was very accomodating. Made the initial purchase 3 weeks ago and I already have the custom retainers. This company will be my go to whenever I need to replace my retainers in the future.

Better than my dentist! A+++

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

I really like working with sentinel, they're fast friendly and follow up well. Any problems are cleared up with a no hassle approach. They make it easy when my dog chews my night guard! It's not funny, but it's funny cause it's true.

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!

My husband and I bought 4 guards from sentinel just so we would have a backup since we like to travel. So I should be able to write 4 different reviews right?? All of our night guards fit great. We are very happy with our whole experience with the company and recommended them to all of our friends. If you're sitting there reading these reviews not sure to make the buy, rest assured this company is the real deal. We are real people who are now customers for life!
