Customer ratings & reviews

This is by far the best mouth guard I’ve ever owned! I bought one from my dentist last for 3 times the price and 1/2 the quality of Sentinel mouth guard! It lasted less than 6 months. I like to use the product I buy before I leave a review and I have used this one! Every night for the last 2 years and occasionally during the day if I’m grinding my teeth due to stress. I have the dual guard that is just starting to show enough wear that I need to replace it. I will never use any other mouth! Sentinel is the best!

Thank you for your comfortable dual laminated night guard and fabulous customer service with Ashley. I once spent $700 for a TMJ splint that lasted less than 2 years. When it cracked in half, I freaked! Then I found Sentinel Mouthguards online and was so relieved that I could get a professional custom-made nightguard for $129! Great deal and a good quality product. I took it to my dentist to check the fit and he approved! He said even HE grinds his teeth at night! (I recommended Sentinel. LOL!) Taking the impression was so easy and it's great knowing they can make a future guard from my impression. As far as customer service, they really stand by their product. When my first night guard split after only a year, they honored their guarantee and sent me another. What can I say other than you guys ROCK! I'm so thankful that you're here. I couldn't live without my Sentinel Mouth Guard!

LOVE it! Entire process was easy. The mold fits perfectly! Good job! I have worn a night guard in past which was ordered from my dentist at the much higher prices, and this Sentinel guard is even better than that one. I ordered the 2 mm dual guard. I barely notice it in my mouth and it fits snugly. I also am thankful it's BPA-free. Highly recommended for protecting your pearly whites!

Hey guys, I've loved the nightguard so far - it's the most comfortable one I've ever had, and I now rarely find myself having dreams where I'm pulling hard candy or gum out of my teeth! Jeremy

Sentinel Mouthguards were great and very responsive to my emails when I messed up the first package they sent me. The second one was just as quick in arriving and the final mouthguard was as well. I have only good things to say about this company.

I just received my night guard and it fits perfectly. I am going to order a second one to have on hand because I travel a lot...this way I can keep one at home and one in my luggage. The process was easy and quick, except the return was delayed by USPS. When I talked to my dentist about needing a night guard they quoted almost $700 for one and I will pay under $150 for two. Also a co-worker just ordered one from her dentist for over $800. This is the way to go if you need a night guard and if you have a Health Reimbursement Account you can use that to pay for the guard. I would recommend this to anyone looking for a quality product (same as you get from the dental office) for an affordable price.

Came on time as promised. Love it!!

Very fast shipping and excellent customer service. Would recommend.

The mold arrived fast but the guard takes a while to make and ship, be patient. It is worth the wait.

The mold kit arrived by 21 September & after mailing in your mold, it takes an additional week to receive your customized mold...which fits perfectly as advertised...
