Customer ratings & reviews

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!

A++ Customer service!! Very pleased with my product..better than my dentist made

Excellent experience all around! The customer service stood out to me because they're so personable. I talked to two different people and both were very helpful and great communicators. I explained my problem. I bite my cheeks excessively and I did not know there to turn. They made me feel confident to choose Sentinel. I'm so glad I did. The guards are well made and work as intended. My damaged area has healed up and the pain had gone away. Much much appreciated and recommended.

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.

I was afraid these weren't going to work for me because the ones my dentist made for me were uncomfortable but these popped in and fit perfect. Comfortable and very high quality.

I'm a pretty hard grinder.. being that I've gone through a few night guards from my dentist which was getting really expensive. My husband did some research and he came across Sentinel and thought I should try them out. I was a little skeptical about taking my own impression at first but it ended up being pretty fun for my husband and I. We sent the impression back in a prepaid envelope. My nightguard came back in about 10 days and I was blown away with how well it looked and fit. I don't know why dentist charge so much seeing that companies like these don't have to. Getting ready to buy another as back up!

Thanks for the brighter smile Sentinel! A++++

Customer service is outstanding. I had a lot of questions and Alexandra was extremely knowledgeable, professional and kind. I got my night guard within two weeks of sending the impression off. Fit is excellent. I chose the 2mm because I wanted strength but wanted to keep it thin in my mouth since I'm a light sleeper. This company is very professional. Couldn't be more thrilled to have found you guys. Thank you!

I bought my night guard in June 2019 and found it to be a bit too tight in the front. I emailed them and they payed for shipping for it to be adjusted, then got it back to me is a very timely manner. The best part was that there were no questions asked! How refreshing, a company that honors its promises without attempting to scapegoat the customer! THEIR CUSTOMER SERVICE IS TOP-NOTCH and the product is great! Comfortable, effective and easy to use! Also, this is a family-owned business...all the more reason to purchase from them!! :-)

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!
