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 live in the city and my orthodontist charges $500 for a replacement set of dental retainers! This is a cost-effective way to save and the quality is even better than I had anticipated! Comes with a mouth guard case for storage. Nice job Sentinel!

The hard option is where it's at! I tried the soft type first and found that it was too flexible for my liking. Switched to the hard guard (they allow you to switch types if you're not satisfied) and this is EVERYTHING! My tension headaches are gone and I love how comfortable it is. I only had to pay the cost to upgrade ($20). Fast, affordable and the fit is fantastic!

I've known for years that Zoom whitening gel is the best on the market. I was surprised to find it here for wayyy less than the dental office. Well worth the investment. The results are quick and stunning. Thanks for making this affordable to the general public!

The absolute best night guard ever! So glad I found this here. My dentist was asking for $600. Fit is true to my mouth and my jaw pain is gone!

CAN'T THANK YOU ENOUGH!! Works great for immediate relief ***** I have a problem area on my tongue that I have been dealing with for many years. It has caused me a tremendous amount of pain and I just couldn't deal with it any longer. I wasn't sure if this would work but desperate times!! I have been using my guards for about 2 months consistently. For the first time in a very long time, my problem area is GONE! Truly a miracle product.

I love the design and feel of these mouth guards. They look great and feel amazing. The lifespan is above average compared to other mouth guards I've owned. As is typical, the material will wear eventually but this is my 3rd one from Sentinel and they last me years. Sentinel Mouthguards material is better than other brands. What I LOVE about the feel is that it stays in place and it's thin enough that I don't want to take it out. As soon as I put it in I can feel quality. This is an important point because I need to be able to communicate with my team. Awesome mouth guards! Awesome company!

Nice and very comfortable bite guards! They absolutely work! Fast and friendly service, high quality custom products!

Just received my mouth guard! The fit is excellent and I can tell this is going to last. Very high quality!

Received my retainer (just needed a lower) and it fits perfect! Really happy with the whole process. I'll be using you guys from now on. Great product, fast shipping!
