Customer ratings & reviews

I clench my teeth. I don't grind them and I've tried every over the counter night guard type available. I wanted to buy from my dentist but their price was double the cost of Sentinel! I decided to go for it and I'm so glad I did. Customer service is an obvious top priority. They were there for me throughout the process, even when I messed up my dental impression. They sent me a new molding kit free of charge. I have an overbite and I was worried how that might affect the fit but the fit is perfect. I wear it nightly and have much less pain in my jaw and no more headaches when I wake up! I also ordered a soft guard along with this type. I wear the soft guard during the day while I'm at work. The soft one is thinner. I would go with the dual layer if you plan to wear this at night for durability reasons but the soft one is fine during the day. Really impressed with the quality, ease of ordering and customer service. Thanks!

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!

This is my 3rd set of retainers from Sentinel due to my dog continuing to steal them off my nightstand. They give me a discount for being a returning customer and the quality has stayed consistently high. I'm always impressed with how beautifully they're made. Way better looking and fitting than my original ones from the orthodontist. Thank you for being of service to us poor folks with strange dogs!

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.

I love my current guard so much, I ordered 4 more during your black Friday sale! The difference between your price and the dental office is exceptional!

I love my first night guard. Had some dental work done so ordering my second! I suffer from TMJ and this guard I wear for my lower teeth. It helps greatly with my jaw pain. No more popping and clicking since I started using it. The Sentinel team is fast, courteous and the product does the job at a price way lower than my dentist. Amazing!

Wish I would have known about this service years ago. Got talked into paying $500 for this at my dentist. You guys have saved my smile and my pocketbook! Thank you <3

This service is remarkable! The customer service is fantastic. Easy process to take my impression and the guard fits perfect. Thank you Sentinel!

Two things: I LOVE this night guard and it was the process was much faster than I had expected. As soon as I took it out of the package I knew it was high quality. The fit is better than any other night guard I've worn. Will definitely be using this service again.
