Customer ratings & reviews

Comfortable fit. I wear this all day, every day. I've had mine for 8 months and so far it still looks brand new. I ordered the thickest version. Very pleased!

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.

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!

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!

Love that this company lets you choose your own thickness. I have the worst gag reflex and needed a very thin nightguard. I'm pretty sure this is the only online company that offers the thickness choices. Happy customer!

1/2 the price of my dentist and just as good!

Didn't realize I would have to make a mold and send it back in to the company but am excited to see how it works. Kit seriously came within 2 days. Eagerly awaiting the final product to come back. Excellent company to work with!!!
