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.

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!

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!

Vey happy with the product! Nice fit and it works.

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 is my second time buying this because my dog got it the first time! I only wear this sometimes during the day and it has helped so much with my stress headaches! It’s easy, worth it and gives the best results.

Item arrived promptly and the fit is great. This is my favorite grinding guard thus far. My teeth are nice and straight but flat from years of grinding and just aging. I was using my old Invisilign tray but it wasn't cutting it so I decided to with Sentinel. I have nothing but compliments to say. I recommend this item to anyone that grinds their teeth. Life saver and worth the investment!
