Customer ratings & reviews

Fast delivery and my new mouth guard fits like a dream! I'm sleeping through the night with it (something I could never seem to do with my other ones) and waking up without headaches and jaw pain. Can't thank you enough! Terrific service!

You have been one of the best customer service experiences I have had. And your products are amazing. The whole user / client / customer experience is incredible. I’m sorry my situation didn’t work out. But I am glad my girlfriend will be able to continue to support and use your services. All the best to you!

Truly great service at a great price! Well packaged box with clear instructions for taking my teeth impression. The mouth guard arrived about a week after I sent my impression off. Looks and fits extremely well. Couldn’t be more pleased. How do I upload a picture? Thanks, Marie

Better than my dentist's guard! The process was easy, customer service was great and when I messed up my impression (and used the extra putty they provided), they still sent me another kit for free! I got the medium thick guard for moderate teeth grinding and my teeth feel protected, Very comfortable, well-made night guard!

Love the flexible, soft material. The cushioning feels good in my mouth and the fit is spot on. I was skeptical about ordering because I just can't stand anything in my mouth but I can definitely tolerate this! Thank you Sentinel! You have won yourself a fan from Wisconsin!

I had this from the dentist the first time, then bought it here, it’s the exact same product but it’s way cheaper here than it is at the dentist. You need to make sure you take a good teeth impression but once you have it, this product is amazing. I wear this nightly and the material quality is very good. Product is affordable and easy to use.

This night guard company was recommended by my dentist. This product works very well and it relieved my jaw pain very quickly. I use it almost every night, overnight, and sometimes during the day. I can feel it when I don't use it! Results are great and the impression kit was straightforward. Turnaround time was quick. I highly recommend!!

I've had other nightguards before, but this is probably my favorite. t fits like a glove. It was easy to take the impression of my teeth, and I appreciate that they included an extra putty pock in case I messed up! I'm a picky person when it comes to anything I have to wear in my mouth so I'm pretty impressed with this nightguard.

Dental night guard that fits great!

They are the absolute best. I have been receiving dental night guards from Sentinel for the past 10 years. All of the staff are consistent professionals and the best in their field. I can't recommend them enough!
