Customer ratings & reviews

This worked PERFECTLY. I clench my jaw during the day and at night and have sensitive teeth because of it. I had a $400 mouth guard from my dentist but it was so uncomfortable I couldn't wear it. I chose the 2mm thickness after talking to customer service. It's thin but the quality is still high. I will definitely never be buying guards from my dentist again. This is a wonderful product!

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

Great quality for the price.They keep the impressions on file for 1 year in case I need a replacement set. They send you the kit for your impressions first. There are 2 different sized trays and extra molding in case you mess up. It’s really easy to do, and my retainers were mailed back within a week or so.

I love these custom guards for cheek biting...I was a bit hesitant to order because I need to wear them all the time as I'm an excessive cheek biter.I was worried they wouldn't be durable enough for night and daytime use but I'm impressed. After a few days, I felt total relief. They are very durable and well made....I will continue to purchase from this company

If you have a cheek biting issue like me, this is the product you need.

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.
