Customer ratings & reviews

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!

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!

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!

Sentinel is really great! The process was easy, the shipping was really quick. Upon receiving my guard, I used it for two nights and it was slightly uncomfortable in one area of my mouth. I realized it was because I probably didn't do the imprint process correctly. I contacted Sentinel, they adjusted the guard and sent me a brand new one. This one is perfectly comfortable and allows me to sleep well at night. No more grinding my teeth and I feel healthier already. Thank you to the team at Sentinel for hooking if up!

Works just as good as my old night guard from my dentist I love how fast and easy the process has been. I use the bottom guard because it's less bulky. So far it fits perfectly, it's high quality and comfortable.

Love these night guards and the people that work there! So friendly and helpful. I have been a customer for 2 years. Always a great experience. Thank you to you all!

Love this brand! This is the only night guard that really works for me! will never go back to other companies. I discovered this company when I visited a wonderful healing center that was treating my TMJ with cold laser therapy. The doctor highly recommended this company and I'm grateful. Sentinel is #1 in my list.
