Customer ratings & reviews

I've continued to wear my night guard regularly and though it does take some getting used to, I have gotten used to it. The fit is spot on. No need for any adjustments. Ordering for my wife and daughter soon.

When something is good, you stick with it. This is my 3rd order from you guys. I've been grinding my teeth since I was little and this holds up better than any of the ones my dentist made. Thank you for an outstanding product.

Love these night guards and the people that work there! So friendly and helpful. I have been a customer for 2 years. Always a great experience. Thank you to you all!

Love this brand! This is the only night guard that really works for me! will never go back to other companies. I discovered this company when I visited a wonderful healing center that was treating my TMJ with cold laser therapy. The doctor highly recommended this company and I'm grateful. Sentinel is #1 in my list.

The process was smooth and I received my night guard for teeth grinding quickly. So far, my jaw feels much better and my headaches are not as frequent in the morning. I think I may need one for daytime too. Ugh! Either way, at least these are way more affordable than my dentist!

So glad they started offering the 3mm night guard. I grind so badly that my teeth were wearing through the 2mm hard guard. I've had this one for 8 months now and so far so good!

Communication is fantastic! The dental impression kit instructions are informative and detailed enough that I can actually tell what's going on. I took a great impression the first time around. Thanks Guys- GREAT SERVICE

Perfect Fit! ***** Easy to use process. Nice quality and very good replacements I hope this product last.

Easy and fast process! I was nervous about taking my dental impression but it was easy. No trips to the dentist anymore! I'm a Sentinel customer for as long as I'm grinding my teeth!

A++ Customer service!! Very pleased with my product..better than my dentist made
