Customer ratings & reviews

Fast relief! Allows damaged areas to heal! This was several hundred dollars cheaper than my dentist and the quality of the product is impressive. The entire process was quick and easy. Customer service is great! I have no complaints. Would buy again!

Best thing on the market for my poor tongue! I have tried everything!! This is the only product that actually works. If you have a tongue biting problem like I do, try it. It works!

It works! Biting my cheek is a real bummer. This product helps cut the pain for sure. Good for managing pain.

Does the job The guards are easy to wear and the process was easy and quick. It definitely stopped the pain from my tongue biting issue.

I've had these guards for over 3 years and I'm just now ordering another set. Thank you for delivering an excellent product!

My nocturnal tongue biting issue had gotten so severe that I was in pain constantly. I tried ointments and the cheap night guards you can get at drugstores. None of it worked. A friend recommended this company to me. I messed up my teeth impressions the first time but I was sent new materials and an email explaining what I had done incorrectly. I was able to do my molds correctly the 2nd time. When I did receive my new guards I was impressed by the quality and care of crafting. I noticed a difference the very next morning in my pain level. Within a few days, my tongue had healed. I wear these religiously and want to share my experience here. Great for severe tongue biters!

It works! My dentist had ordered me a guard for my cheek biting problem and after just 2 nights I knew there was no way I was going to be able to wear it. It was a hard guard unlike these soft ones. It pressed against my teeth causing me to wake up with pain and soreness. These guards are very comfortable and prevent my teeth from catching my cheek and doing damage. Job well done Sentinel team!

I've had guards from other companies and not one of them have taken the time to shape the guards so beautifully and it matters! They all were cut straight across but these fit soo much better. I don't normally leave reviews but had to jump on and tell you how pleased I am with the fit and quality. They're thick enough to protect my tongue but not too thick. They really are made for me only. Worth every penny!

When I couldn't get my dental impressions correct I became unsure that this product was right for me. I was about to give up but your customer service is outstanding. The girl on the phone told me she had worked in a dental office for almost 20 years and she walked me through taking my own dental impression. Once I understood it, I took two great dental impressions. I sent photos of them to her and she immediately responded back with an A-Okay. Sent them in and received my two perfectly fitting guards. I've been wearing them consistently with much success. Thank you Sentinel. You are a dream to work with.

Excellent all around! 5 stars!
