Customer ratings & reviews

This product is fantastic! This is for any mouth pain including cheek and tongue biting. I sent back my impressions and the guards were shipped to me within a few days. Honest company with a great product!

The product fits great! I've slept with it for about a week now and so far so good. I do bite my cheeks a little but I'm mainly using these as teeth protectors for my grinding and clenching. I'm hoping they hold up over time because they are soft and a little flimsy.

Can’t believe I’m writing a product review for my tongue biting problem. But here goes. This is the most comfortable mouth guard set I’ve ever worn ever. I am so impressed by this brand. The customer service was extremely helpful over the phone. The entire process was quick and easy and the mouth guards are a perfect fit. This is a wonderful product!

They sent me the impression trays and putty, and I chose the correct tray size. The smallest tray was too small and cut off my molars. Took my impressions and mailed it off. The teeth guards arrived within 10 days. I popped them in and they both fit like a glove. It works GREAT and I have no soreness. I'm 69 and thought I would never get used to wearing these. I am keeping this product as I am very satisfied.

Amazing quality and service! Couldn't get to the dentist because of the pandemic. I was having major pain in my cheek from subconscious biting during the night. Ordered these online and so glad I did. They fit great immediately out of the box. Excellent product and outstanding customer service!

Excellent experience all around! The customer service stood out to me because they're so personable. I talked to two different people and both were very helpful and great communicators. I explained my problem. I bite my cheeks excessively and I did not know there to turn. They made me feel confident to choose Sentinel. I'm so glad I did. The guards are well made and work as intended. My damaged area has healed up and the pain had gone away. Much much appreciated and recommended.

Love it. Have stopped teeth from damaging my tongue.

I screwed up my dental impressions. Both of them. I took too long to mix the putty both times. Guess I'm bad at reading directions. The company did send me a redo kit free of charge. I was successful the second time around and got my guards. They really do fit like a glove and my tongue is healed! I highly recommend your company! A+++++

I'm putting the review here because this is the intended purpose. That is, to stop my cheek biting but I actually ordered the hard dental retainers for this and it works exceptionally well. I don't know if anyone else has ordered the hard ones for cheek biting but they work too. Basically, the plastic surface disallows the cheek to "catch" between the teeth. I'm sure the soft ones are fine.

This has been a problem since I was a kid. I bite the inside of my cheeks until they bleed. I do it in my sleep so I am unaware of it. I've tried a lot of methods to stop the cheek biting. I think I do it more when I'm stressed. I bought these dental guards because I can't seem to stop on my own. I can sleep with them in comfortably. I can't tell you how nice it is to finally have my cheeks healed up. I would highly recommend this product for anyone that has the same issues as me. 10 stars!!!! -Bill
