Customer ratings & reviews

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!

My review is consistent with all of these other reviews! Very easy process with clear instructions. Kudos to these guys for saving me so much money!

Totally worth it! service is top-notch and the fit is spectacular!

Love the free shipping and these are the best prices on the internet. I've been through other companies and you guys ROCK!

This is a lifesaver for me! I was cracking my teeth and having horrible jaw pain. The store bought guards weren't cutting it and the dental office price is unbelievably high. I chose Sentinel Mouthguards because of the price point and the 1 year warranty. So glad I did. Absolutely terrific company with a great product!

I bought this night guard for my son who grinds his teeth. We unsuccessfully attempted the first mold but Sentinel sent another kit out right away. So happy I could get this mouthguard at an affordable price. My dentist wanted to charge a small fortune! Thanks Ashley & the rest of the staff. You guys are great!
