Customer ratings & reviews

Excellent product and price

I am impressed with the quality and integrity of this company. I didn’t know what to expect and took a chance. If you are unsure of your bite mold you can take pictures and email to Sentinel and they will advise. My mouth guard fits perfectl and comfortably. Also, I needed to email Sentinel because I hadn’t recieved my guard (my mail person often delivers to the wrong house or development!). The response was prompt. I highly recommend Sentinel.

Functional, Comfortable, and Invisible

I have developed a habit of grinding my teeth during the day. This new mouthguard fits in such a way that it both prevents grinding and is completely invisible. I can speak and drink comfortably while it is in. I highly recommend it, especially for daytime grinders like me.

Helps when lifting

I tend to clench my teeth sometimes when lifting weights. This guard really helps.

Fits well and feels great

Great Fit!

Perfect

Simple, easy to use and the guards fit perfect

The mouth guard for severe teeth grinding is great. However, as of to ate I have not received the upper mouth guard. I ordered it the same time as the lower guard.

It's been 5 years and I still use it nightly!

I ordered this more than 5 years ago and my mouthguard is now clearly scratched with bite marks, but still holding up beautifully. This was an exceptional product that I would definitely order again (but so far haven't needed to!)

Not too large, fits great, customer service was excellent!

Great Fit

Great Fit and Great Durability!
