The Sentinel Hybrid/Dual Laminate Dental Night Guard (soft inside/hard outside) is the newest style on the night guard scene and gaining a lot of popularity!

This night guard is available in 2 thicknesses & takes a special machine that combines layers to give a soft inside and a durable, hard outside. The result? A cozy, soft gel-like feel against your teeth coupled with a hard outer shell for the long lasting protection you need.

Why choose a dual laminated night guard? The two layer construction wherein a soft layer is bonded to a hard outer layer allows a comfortable wear.

There is no comparison to wearing a true custom made dental night guard and the Sentinel Dual Laminated Dental Night Guard excels in every facet you have come to expect; fit, durability and comfort.

    I would agree with everyone below. Sentinel’s customer service is #1. I received several emails throughout the process keeping me informed. I was thinking to myself another automated email system but they were all informative, useful emails with my tracking information etc. They are quick to respond through email as well and I received my night guard within about 3 weeks from the order date. *****

    Messed up my impression the first time. Sent a picture in and they told me that it wouldn’t make for a good night guard so I used the extra putty that was in the kit to try again. About 1 1/2 weeks later I received my guard. I’m glad they care enough to supply an extra putty pack for a retry and provide such friendly customer service. Will be back because I don’t think this teeth grinding habit is going anywhere!

    I have TMJ and absolutely have to sleep with a nightguard. My dog chewed mine from the dentist and I desperately needed an affordable replacement. This did the trick! Very happy with the product and excellent customer service!!!

  • Mary Paterla

    This guard is the best I’ve ever worn. I’m missing all of my right side molars & still a superb fit. Hands down! The best! , Mary B.

  • Bettina D.

    I have tried those boil-it-yourself mouth guards and they never make it through the night. They always end up on my nightstand.

    I gave Sentinel a shot. I was probably their worst nightmare of a customer. I had a ton of questions and low expectations.
    I got the kit to make a mold quickly, followed the instructions, sent in my pictures of my impression to Sentinel. After approval, I sent the mold to their lab using the shipping package they sent me. Sentinel took about 7 days to make my guard. I received it and immediately LOVED it.

    The guard is not bulky at all. It is very thin and comfortable to wear. I highly recommend this guard!

  • John C. Smith

    Thank you!
    Sentinel mouth guards has made a huge difference for me. For years dentists would talk to me about my teeth grinding and then want to charge me $600-800. I was always concerned with the fit and whether I’d take it out in my sleep. I had one over a decade ago and it didn’t stay put over night. When I heard about Sentinel and saw the savings of going through you direct, I knew I had nothing to lose. The value has well exceeded the cost. The fit, comfort, & protection have made a difference in protecting my teeth. Thank you.
    Now my only question is in the next one I order will I try the all hard/soft or stick with the dual laminate.

  • Sal N.

    The putty hardened up on me too quick the first time I tried it but the second time I made sure I paid attention to the time. Love the fit of my bite splint. Easy to sleep in and overall easy process.
