Customer ratings & reviews

I received my new mouth guard, at first I thought it was too tight. But I continued to were it and it stretched out to a good fit. Satisfied Customer. Gary C.

Sentinel Mouthguards were great and very responsive to my emails when I messed up the first package they sent me. The second one was just as quick in arriving and the final mouthguard was as well. I have only good things to say about this company.

The Sentinel impression kit to make your dental molds is well done.It comes with 2 mouth trays and two sets of putty for two impressions (if you make a mistake). Taking my impressions was easy and the custom guard that arrived fit my mouth perfect. It also came with a nice retainer case and instructions for cleaning. Happy customer!!

This is my journey- I started to notice the effects of my teeth grinding and needed to start protecting my teeth. Admittedly, I tried to go the cheap route at first. Those guards are about as useful as a hockey puck in your mouth. I went through another company before Sentinel but it didn't work out. I couldn't get my impression right and they wanted to charge me for another kit. Resulted in a refund. Sentinel had amazing reviews so I decided to give it a try. I wear my Sentinel guard every night. The fit is perfect. It has not changed shape and I've had it for over a year. My teeth sensitivity and jaw pain is gone. Sentinel is a life saver. Great company! Great product!

A wonderful company! VERY VERY happy with my guard!

I have been ordering from Sentinel since 2012. Customer service has always been so friendly and helpful. The night guards have helped my mouth tremendously. This is a great, affordable service. I love you guys!

As a professional fighter I'm always looking for good solid gear that can last through intense training while giving the comfort to focus on what I need to do. The fit is excellent. The guys at Sentinel are great too. Easy company to work with. I've ordered a few guards over the years. Can't beat the fit.

Have been using my 1st order for almost a year and they are great. Quality is the same if not better than the ones I got from the dentist!

Got a different brand the first time I ordered online and the mouth guard was okay. Should have went with this brand to begin with. Noticeable difference in quality and fit. Turn around time was fast too!

This was a replacement retainer for another I had from a dentist which wore out in a year and a half. The Sentinel retainer fits very well, is thinner even than the old one and the price more affordable. Customer service was excellent - the first retainer I received did not fit perfectly so I contacted them via Live Chat and response was timely and helpful. Sentinel recast another retainer and also sent another dental impression kit in case the new one didn't fit. Well, the recast retainer fit just fine so no need to do another impression. When Sentinel says they stand behind their product and want the client to be 100% satisfied, they follow through!
