Customer ratings & reviews

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!

Tongue and Cheek Biting Relief Mouth Guards

Great service and great product

I’m really happy with my bleaching trays. Sentinel was very helpful when I needed help with my molds. Delivery was quick. Price was very good. I recommend them to anyone looking for teeth bleaching.

Mouthguard review

I was inadvertently biting the inside of my mouth, particularly when I slept, and the action/pain would awaken me. When I began using the Sentinel mouthguard all the accidental biting stopped and provided welcome relief. Thank you for your product and I highly recommend it.

I love Sentinel Mouthguards

I have been ordering Sentinel Mouth guards for years. The company is responsive to questions and problems. They help you every step of the way towards getting a good fit. The product arrives in a timely manner and lasts a long time.

Excellent

Most comfortable and durable bite guard I have tried.

Works great and lasts so much longer than the one the dentist made.
