Product Reviews

  • Adam Green

    I just got my Sentinel guard in yesterday and as I’m sure many others are, I was skeptical to order online. I’m happy to report the impression process was much easier than I thought it would be and the guard is the most comfortable one I’ve ever had! Looking forward to wearing it at work. Hopefully these daily headaches will stop once and for all!

    I love my current guard so much, I ordered 4 more during your black Friday sale! The difference between your price and the dental office is exceptional!
