Customer ratings & reviews

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.

Easy and fast process! I was nervous about taking my dental impression but it was easy. No trips to the dentist anymore! I'm a Sentinel customer for as long as I'm grinding my teeth!

I went with the thickest option. Love the customer service, process and the thicker material is still very comfortable (I was worried it wouldn't be). Sentinel does an outstanding job all around.

Can't go wrong with Sentinel. Great group of people that offer a solid night guard solution. I have paid the expensive dental price in the past but no more! The internet is here and there are better ways of doing things. Thank you Sentinel!
