Have some additional questions about ordering your night guard?  We've got you covered. Your most FAQ's about night guards for teeth grinding.

Here's a tip when deciding on which night guard is right for you:

Remember that if you do not wear your night guard for a while your teeth may naturally shift overtime. This can cause your night guard to fit incorrectly. So, if you do not wear a night guard often (consistently), it's probably better to choose the Sentinel Soft Dental Night Guard.

    Just a beautiful fit! Thank you!

  • Isabella Peters

    Ordered this for my mother and was very skeptical as she is a light sleeper and needed something tolerable for her night teeth grinding. We decided on the thin version. I love the six month guarantee and she loves her dental guard! Great customer service. Smooth process. Thank you!

  • Rebecca McBrien

    Just ordered three more to last me for a few years. Thank you Sentinel. You’ve literally saved me hundreds. Hugs to you!

  • B. Kellner

    These night guards are wonderful. My husband and I both purchased. We had not bought decent night guards since 2000 and I was tired of how quickly the “cheapos” wore out. We ordered these night guards and will continue to order more throughout the years. Don’t waste your money: buy these instead!

  • J. Williams

    This is my 2nd Sentinel mouth guard – Sentinel is a great company, and I love the quality of the products and the prices are unbeatable!

  • V.R Rose

    Had my dentist make me one of these a few years back and this one is just as good as my first one. Hopefully I’ll be able to hang on to this one. Great job!

  • Victoria Reynolds

    My teeth are really flat. I just needed something to keep things from worsening and it’s nice to find an inexpensive alternative. Thanks Sentinel!

  • Teddy J Dowell

    I only wish I would have know about Sentinel sooner, a friend referred me here and I’m completely satisfied. Great company!

  • Lillian Kemp

    Great service! Great product! Thanks!

  • Cal K.

    Just wanted to let you all know that I have paid the $500 to the dentist in the past and I am so glad I don’t have to do that anymore. This night guard is better quality and a better fit than my $500 one I bought through my dentist. Amazing! Thank you!

  • Gary B. Phoenix, AZ.

    Superb service and great product. No complaints!

  • Randell W. FL

    I contacted Sentinel because I have a very particular case in which I only needed a partial guard made for one side of my mouth. My dentist had been constructing this specific type of guard for me for years. It works well for my jaw condition but I do wear them down after a while and need replacements. This was becoming costly. Someone told me about Sentinel night guard lab & I’m happy to say they (Sentinel) have made me two guards about two years apart from each other and both fit and work perfectly. This has been a great company to work with and a steal compared to what I was paying before. Not going back to the dentist. Sentinel has earned a customer for life.
