Customer ratings & reviews

Impressions were easy to take. The instructions were easy to follow and that was the part I was most nervous about. I have a bad gag reflex and worried I couldn't handle anything in my mouth. This was not the case at all. Easy, easy. I received my guards and I can tell this company cares. They were beautifully crafted and fit like a glove. I now go to sleep not worrying about biting my cheeks. The relief I feel is well worth the investment.

Love that I didn't have to go to my dentist to get these, super impressed with how well made. 5 stars!

These guards are the best fitting. Exceeded my expectations. They are thin and comfortable but still offer the protection my tongue needs. No more pain and constant soreness.

I would not use any other company but Sentinel! Not only are their products high quality and fit like a glove but they're fast and have great communication/customer service. I'm a Sentinel fan for life! Thank you!

If you're a tongue biter and you're on the fence, just do it! This product WORKS. I've tried everything else and this is the only thing that has saved my tongue. By wearing the guards nightly, I protect my tongue from my teeth. My tongue has healed, I'm pain free and I can eat spicy foods again!! Highly recommend this product for tongue biters!

Sounds a little over the top but this has been life changing for me! To be in pain constantly was my life. I couldn't eat many foods or drink certain beverages. Anything acidic or spicy killed my tongue due to a severe tongue biting habit. I was absolutely desperate. I saw this advertised and went to my dentist to see if they could make the same thing. They wanted to charge me $800! I couldn't believe it. Went with Sentinel and I'm so glad I did. I paid for the expedited shipping because I couldn't wait much longer.Well worth it. Fast turnaround, excellent communication and my tongue felt relief almost immediately.Completely healed within a week of consistent use. Beyond grateful!!

Can I get an amen!!! I am a person that suffers from epilepsy and I bite my tongue during seizure episodes which typically for me, occur at night. I wear these nightly. They're thin and very comfortable. I feel so much better knowing that I'm not going to bite my tongue if an episode does occur. You give me peace of mind Sentinel. And for this, I am very grateful.

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.
