Customer ratings & reviews

I ordered a lower guard to start. When I received it, I realized my tongue likes to flick it up at night. I called the company and they switched me to an upper guard. I already had the upper impression on file with them because with these heavy duty guards, they require both an upper and lower teeth impression. Super easy and convenient! I was sent the upper teeth guard and it fits perfectly. This product is excellent and the customer service is amazing!

A+ service. I recommend to all of my family and friends!

I have gone through so many professionally made dental night guards and I've never liked any of them. This mouth guard is not only a great value but it fits over my teeth perfectly. Because they take the time to shape it to the contours of my teeth, it actually fits to my teeth like a glove. Just because you pay to have a custom made night guard doesn't mean that it's going to fit like this. I have had several guards made by dentists that didn't fit this good! These technicians know what they're doing. I recommend this company to everyone I know and I'm happy to write a glowing review for them.

Great company! Great product! I highly recommend Sentinel Mouthguards!

Best sleeping night guard I've ever used Much easier to sleep in than the one I got from my dentist. It's still thick but much less bulky if that makes sense. May purchase a second one while it's at this price (dentist charged $500).

I bought this on Amazon originally and have been a customer ever since. Great find and the price is right. Wearing a night guard has helped me tremendously.Instead of waking up with my jaw screaming at me, I just wake up like a normal person now. I do have to wear mine nightly and notice that the jaw pain starts creeping back up on me if I'm not consistent. The teeth impression kit is straight forward and they give you an extra putty if you mess up.

Although my first guard didn't fit right, Sentinel was quick to make me a free replacement and it fit perfectly. I didn't mind the hiccup because I literally saved hundreds of dollars by not going through my dentist. Easy to get used to wearing and I love their attention to customer care!

I have tried night guard from other online manufacturers for heavy teeth grinding and this is the best. Fit is good, fast delivery.

Needed an adjustment. They had me print out a tooth chart and circle the teeth area that the guard was too tight. I sent it in and it was very quickly returned to me with the correct adjustments. My guard fits great now and I am pleased with the service.

Beautifully made. I have to admit I was a bit skeptical in the beginning. It was a bit stiff and uncomfortable but then after a few nights it just seemed to loosen up and adjust to my mouth. For the price versus what my dentist wanted to charge me, I feel good about my purchase. It really is a nice mouthguard. I appreciate the extra attention to the shape. I've had mouth guards in the past that they cut straight across and even had jagged edges. This one is nicely done. Definitely worth it.
