    Can’t imagine why I will ever return to a dentist for a dental night guard. You guys are a serious money saver. Thanks bunches :))

  • Darren Brock

    This team really does go to great lengths to meet customer satisfaction. I messed up my first dental impression and was quickly shipped another for free. Then wanted to change types after I received my soft night guard. They upgraded me and I just had to pay the difference in price. Way more flexible than my money hungry dentist! Great customer service.

  • Briana Snellgrove

    When my dentist said he’d give me a deal on my second night guard I was stil heartbroken at the price. So thankful for the internet. Also, pro tip: I use castile soap to clean my mouthguard. Dr. Bronners on Amazon sells a big bottle of it. Better than the harsh toothpastes and denture cleaning solutions! Mouthguard fits perfectly . A+++

  • Josh Turner

    Communication is fantastic! The dental impression kit instructions are informative and detailed enough that I can actually tell what’s going on. I took a great impression the first time around. Thanks Guys- GREAT SERVICE

  • Ronnie C

    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!

  • Ava

    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!! 🙂

  • Dan M. Salt Lake City, Utah

    Had a little trouble taking my dental impression. Had to go through three tries but third times a charm and I got it!
    The night guard fits great. So far so good. Thanks!

  • Robert

    They have a great product for a fraction of the cost that you’re dentist will charge. The customer service is outstanding, I had an issue and they took care of it immediately. They kept me informed during the entire process. I would recommend them to anyone.

  • Chris berry

    Worth every penny! I do all my shopping online already as it is so why not a night guard. Thank you for the great nightguard

  • Connie Dawson

    Prompt shipping, fast turn around time and high quality product. Can’t beat it!

  • Leah Morris

    I am just writing to thank you for all the work you did to get me a mouth guard that fits comfortably.
    Sentinel mouthguard has great customer service. I had some problems with the original fit of my mouthguard, and they helped me return it 3 times and sent me a new impression packet. I am now completely satisfied with the fit. I would recommend them to anybody. Real value for the money!

    I really like working with sentinel, they’re fast friendly and follow up well. Any problems are cleared up with a no hassle approach. They make it easy when my dog chews my night guard! It’s not funny, but it’s funny cause it’s true.
