Product Reviews

  • Alex Jackson

    The process was smooth and I received my night guard for teeth grinding quickly. So far, my jaw feels much better and my headaches are not as frequent in the morning. I think I may need one for daytime too. Ugh!
    Either way, at least these are way more affordable than my dentist!

  • Nicholas Cook

    So glad they started offering the 3mm night guard. I grind so badly that my teeth were wearing through the 2mm hard guard. I’ve had this one for 8 months now and so far so good!

  • Sentinel customer

    Excellent product. Works exactly as advertised. I can breath easier, drink and even speak clearly. But even better is that it took us 3 attempts to mold the impression correctly and each time, Sentinel was patient with us and helped us until we got it right. Remarkable product. And let me add that my wife and I have had many of these from the dentist over the years. These are just as durable.

  • K.D.

    Product works great! It comes with a nice storage case. Definitely recommend!

  • A. Valenzuela

    I was looking for a safe mouth guard and researched heavily. I asked several companies what was in their materials that they use and most were either vague or didn’t respond. This was the only company that I found that was willing to be transparent about the products they use.
    I did confirm that the plastic is BPA free which was my main concern. The night guard took many nights to get used to but I finally enjoy wearing it. Thank you for being a reputable company. -Alicia

  • Art C.

    I love this guard. It fits perfectly. I can’t sleep without it and it’s helped my TMJ tremendously. Thank you! -Arthur

  • Sandy Mcqueen

    Top notch service and outstanding, high quality product! I love your night guards and they have saved my life! I was spending so much unnecessary money at the dental office and then when I couldn’t afford that, I went to the drugstore options. Ugh! So happy that you have an affordable option that LASTS! Love you guys!

  • Melissa

    The product is fine but ultimately didn’t work for what I needed it for. Resulted in a refund. Refund process was easy.

  • Shana Odlen

    Spoke with Alexandra and she was very helpful and recommend that a ask for some extra putty!!

  • Rebecca Streeter

    Better than my dentist! A+++

  • Mel H

    I got this for my elderly mother because she grinds her teeth VERY badly at night. Her mouth is tiny, and since the process requires taking a teeth impression, I asked for extra material. Getting the teeth impression on her tiny mouth was a little difficult but only because again, small mouth. It molds and hardens very quickly. in a matter of 2 minutes, so it may take a couple of tries to get it perfect, but overall it’s easy to use, and has easy directions. She says the mouth guard fits her well. A good purchase for the money in my opinion.

  • Jake B.

    Great product, not too bulky. Way less than the dentist. Happy customer!
