    Being able to use my FSA card made the an easy buying decision. The molding process did make me a little nervous but it’s explained very well in the written instructions and video. They gave me an extra set of putty too in case I needed a reattempt.
    I sent them a picture of my impression and received a reply very quickly.
    Excellent guard and excellent service. I will not hesitate to order another guard from Sentinel.

  • Nick K.

    This service is remarkable! The customer service is fantastic. Easy process to take my impression and the guard fits perfect. Thank you Sentinel!

  • Thomas D.

    My dentist recommended I get a dental guard because of my grinding but their price was ridiculously high, so I tried a few different types from the local drug stores including the most expensive one but I could never sleep with them in.

    I finally ordered the “thicker” Sentinel Mouthguard. It’s a softer plastic that feels much better in my mouth and I am now able to fall asleep without any problems. I have been wearing this nightly for several weeks now and it is working great.

  • Silvie Antonius-Baldosa

    Beautifully crafted and it does the job!!

    This guard is awesome.It does great job of keeping my teeth from wreaking havoc on each other. And for the price, it is just what you need.

  • Michelle Zwang

    I originally ordered the hard night guard but found it to put too much pressure on my teeth. I contacted customer service and they made me a soft guard as part of my satisfaction guarantee. They even refunded me the price difference as the soft guard is a little less than the hard. Their customer service is excellent and they have gained a customer for life. Thank you!!

  • Cindy Lee

    Don’t hesitate to order from this company. They’re the absolute best. I’ve been a customer for over 7 years now. Long time returning customer and always the same level of consistently excellent service. -Cindy

  • Sarah S.

    I love love love this night guard and the convenience of this service. The first thing I do in the morning is scrub it with some liquid soap, rinse it, dry it and put it right back in its case next to my bed. This way, it’s ready for me at night and it stays clean and clear. I had one years ago that I didn’t take care of and it turned a disgusting yellow. Never again! This option is far cheaper than my dentist and the quality is superior. I will definitely buy this again!

  • Robert Castro

    I couldn’t be happier with this product. Beautifully made and high quality. Super convenient service. I HIGHLY recommend.

  • Sam P.

    I’ve ordered from various vendors online and Sentinel is by far the best. My mouth guard fits like a glove. I sleep with it every night. I recommend you guys over and over. Thank you!

  • Daniel Estevez

    Very happy with the level of customer service and the high quality product. If you’re on the fence about it, it’s definitely worth the money.

  • Shanda O.

    Very good night guard at a decent price.

    I tried the ones you boil & bite but it was so bulky and made me gag. These are custom made from an impression from your teeth and there is a HUGE difference. When you do the impression, make sure you do it in front of a mirror and use the bigger sized tray. Not the smaller one. I made a mistake the first time but they include an extra set of putty for a retry.

    Overall, great service from start to finish!
