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!

I love love love this product! My tongue is too large for my mouth and I searched high and low for a product that would work for me. This is it! I wear these during the day and at night. I do keep them out for several hours a day and make sure to clean them. So far they're holding up well. Will update if needed. -Francis

This product saved my cheek!! It was such a disaster. I could barely eat and I kept accidentally biting it to the point that I thought I may have to have surgery. The guards kept me from biting and the damage was noticeably better after just a couple of days. Life saving product!! Thank you. Thank you. Thank you!

I have an obsessive compulsive disorder that makes me repetitively bite the inside of my mouth. I've gone to doctors, taken medications, tried to lower my stress levels, all the things that they say to do and none of it worked. The tongue and cheek biting guards are the only thing that has made a difference for me. The process was a little longer than I hoped for but at the price I guess it's a lot better than going to the dentist. I'm happy to have found a solution and I highly recommend. Customer service is very nice too.
