Customer ratings & reviews

Can't stop wearing it! Has helped me so much. So glad I decided to wear this product because I worry about my teeth during the day and at night. Comfortable, light and easy to mold to your teeth. Great product!

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.

VERY COMFORTABLE This is my honest review. I have crooked teeth and was very concerned about how this would fit over my teeth. I took a bad impression the first time around. The team at Sentinel sent me a new kit. They did not charge me for the 2nd kit. I took my time reading the instructions and got a good impression. I usually work about 7 to 8 hours at my computer per day. I wear this guard during the day and it works well. My jaw feels better. I feel good knowing I'm not doing damage to my teeth now. I bought 2 more of them during their xmas deal as backups. Go for it. I definitely recommend them.

So my dentist told me that I've developed a mild teeth grinding problem. AND my terrible insurance plan did NOT cover the required night guard that I was told I needed. Why? I still don't have a clear answer. But after some research online, I now have a custom night guard now that was hundreds less than what my dentist quoted me. It's a perfect fit. I even showed it to my dentist and he said it was fine! Umm okay?! Thank you Sentinel!

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.

Glad I gave them a try! The fit was off when I received my lower guard. Upper fit perfect. They sent me a new impression kit and remade my lower retainer. Fits great! Happy with my purchase and would recommend. Suzanne in customer service is great!

A bit time consuming but worth it. The guards are a big upgrade from the ones I was using from Walmart. While it is a bit time consuming to have to make the molds then wait for the product to come, this is your best bet when compared to the cheap ones from the store. If you're looking for something with high quality but accessible price, this company is a good one.

Love it. Last time I went through a different seller and the quality was not half what yours is.I am very happy.thankyou

My most recent order is the second time that I have ordered from this company. They are sturdy, and very reliable. The reason for needing new ones is that my back molars grind so intensely at night that I ground through the first one. I think I ordered the first in 2017 so it did last me a while. I would highly recommend this product to anyone looking for a quality night guard.

I've tried several night guards from other companies and my best experience has been with Sentinel Mouthguards. High quality mouth guard and very responsive customer service. The guard arrived in a timely manner and fit good right out of the packaging.
