Customer ratings & reviews

Best teeth guard I've ever worn! Slim design, light and fits like a glove! The one from my dentist didn't compare to this one. Comes with a nice storage case as well. Thanks guys for an amazing product!

HIGH QUALITY AND HIGHEST LEVEL OF SERVICE ***** I 100% recommend this dental night guard delivery service. They remove all of the excess plastic for a slim fit. Not at all bulky in the mouth and crafted with care. Thank you Sentinel team!

My first time ordering from this brand. Impression kit came very quickly and included extra putty in case I needed it. The cost is worth it to be able to complete it from home without having to go to the dentist. The product fits very well and has really helped reduce my jaw pain.

Customer service is remarkable! I had ordered from another company and after messing up my impression, they tried to charge me $25 to send out another impression kit. Sentinel sent one for free. No questions asked. They're fast, friendly and less expensive than the dentist. I highly recommend. *****

SURPRISINGLY EASY AND FAST I developed a mild teeth grinding problem and needed a night guard. After reading a couple of reviews, I felt comfortable ordering. The impression kit arrived super fast. I took my first impression but mixed the putty too fast. Luckily, the kit contained putty for a 2nd attempt. Nailed it on the second try. I emailed Sentinel to verify the quality of the impression before mailing it in. They responded very fast and ok'd it. Recieved the night guard and it fit like a glove. I've been wearing it regularly (my dentist will be proud). If you're wondering if this is the same quality product as the dental office that charges $500, yes it is! Thank you Sentinel Mouthguards

I love love love this product! My tongue is too large for my mouth and I searched high and low for a product that would work for me. This is it! I wear these during the day and at night. I do keep them out for several hours a day and make sure to clean them. So far they're holding up well. Will update if needed. -Francis

This mouth guard has helped my jaw tremendously! I could barely chew before wearing this. My jaw was so bad off I was making crunching sounds while I ate and had to chew softly. I'm still trying to be mindful of my eating but NOT due to pain from grinding and clenching. Thank you!

Wow! Just terrific customer experience all around. I received my night guard today and if fits perfectly. Thank you!!

My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It's a lifesaver! I can't sleep without it now! 5 stars and I'd give 10 if I could!

Durable enough to handle my jaws and that's saying a lot! I have gone through so many of these but the material is strong and I love that they don't add any resins or acrylics. I'm sensitive to chemicals. This is the safest, best night guard I have found! A++++
