Customer ratings & reviews

This mouthguard is so comfortable. The quality of material is great. It's flexible, bendy, light weight and the product fit perfectly well to my imperfect teeth. I've tried the store bought types. It's hard for me to find my size because of my crooked teeth. This custom option is a perfect fit. I've told so many people about you guys you should pay me for advertising your brand????

Saw that this site was mentioned on Reddit as a good place to get a night guard so I decided to give it a try. Very, very, glad I did! Saved me 500 bucks! I've sent some friends this way too and they were all happy as well. Thanks a ton!

Fast delivery Love my custom trays! I whiten during the day and no one even notices. A++++

Solid product! 5 stars! Highly recommend!

100% Satisfied Customer!! I've been through so much with my jaw. Popping, pain while eating, teeth sensitivity..it was dominating my life but I couldn't afford the dentist made ones. I opted to go with Sentinel Mouthguards and I couldn't be more pleased. The mouth guard fits beautifully and my pain is GONE! You guys are serious life savers.

They sent me the impression trays and putty, and I chose the correct tray size. The smallest tray was too small and cut off my molars. Took my impressions and mailed it off. The teeth guards arrived within 10 days. I popped them in and they both fit like a glove. It works GREAT and I have no soreness. I'm 69 and thought I would never get used to wearing these. I am keeping this product as I am very satisfied.

The fitting process was quick and easy and didn't take long for the custom night guard to arrive (approximately 3 weeks from start to finish). Upon first wear, I was in shock at the positive difference! My first night went smoother and I felt like I got better sleep & zero soreness upon waking. This company will even keep your teeth impression on file for future orders which is a major plus. Thank you Sentinel!

This is a really good deal. My dental office wanted to charge me $400 for the teeth whitening. Found the same thing here for $150. The Zoom whitening gel lasts a really long time. You only need a little bit each time you apply it so 3 syringes lasts forever! Well worth it.

Love the look and feel! I chose white. It’s thin and if you didn’t know any better you’d barely be able to tell I have one in. I got the thinnest one because I have a bad gag reflex. Impression putty process was easy. Will use again in the future!

I need it as a lower mouthguard to protect from biting my lip during sleep. I tried a over-the-counter solution which was worthless. Found sentinel on the Internet. Was impressed with a customer service representative, Ashley, who took me through the process and inspired confidence in the company. After receiving the mouthguard, I wanted a slightly deeper impression. Spoke with Ashley again and she arranged to have a new guard shipped with no questions asked and no additional cost. The new guard fits perfectly. I would recommend this company without reservation. Thanks Ashley!
