Defending Your Smile Starts Here

Teeth grinding and clenching cause headaches, jaw pain, and teeth sensitivity. Additionally, teeth wear, cracks, chips and breakage are all common side effects. We understand the short and long-term effects of teeth grinding and clenching. Teeth wear, cracks, chips and sensitivity don’t just happen overnight but once it happens, costly dental work is needed.

Ask any dentist-there is nothing better than natural, healthy teeth. With Sentinel Mouthguards, your teeth are comfortably protected and your tooth structure stays preserved.

    Beats the heck out of those cheapo CVS night guards. I have been wearing mine for 8 months now with zero problems. Perfect option for me. Thx!

  • Melinda B. -Utah

    Fast, affordable, excellent product! Simply great! Thanks Sentinel team!

  • Lorena Briggs

    This is my second experience with an online night guard company, The first one gave me a shoddy product and then they wouldn’t answer their phone. I shopped around this time. Some other labs I saw didnt even have a phone number to call. Sentinel Mouthguards answered my call and tolerated my million questions. Got the kit within a few days. Th whole process took about two weeks. I am very pleased. Definitely will use this company from now on.

  • Sandy E. Lincoln, NE

    I was really nervous about ordering because I have missing teeth on both my uppers and lowers and was worried about how well it would fit.
    Received my guard today and wow! The fit is just flawless. I’m glad I went with the soft because I think maybe the hard would have been too difficult to get this great of a fit? Maybe I’ll try the hard one next time. Thanks a ton!!!

  • Alex R

    I checked out a few sites before choosing this one because I wasn’t sure if I was able to get a good fitting night guard since I don’t have the straightest of teeth. I was worried
    only a dentist could get the right impression. I went for it anyways and it has fit perfect since. No more jaw pain and I’m sleeping better. Sentinel was really easy to work with and I’m very impressed.

  • Griffin P.

    Affordable and comfortable. Worth the time involved to save so much money. I feel like I was being robbed by the dentist all these years. Thanks Sentinel team!

  • unknown

    I clench my teeth. I don’t grind but I kept cracking crowns which is just ridiculously expensive. The thought of wearing a mouth guard over my teeth while I sleep just seemed unlikely. I tried the ones from CVS with no luck. I asked for a thin version of the soft guard and it’s perfect! Sleeping with it in took some training but if I have to wear one I think I got the best one I could get. Thanks a million guys!

  • Misha B

    Amazing customer service! You can tell this company are real people who care. No robots and very nice. Ashley answered all of my questions and was very friendly and knowledgable. Give her a raise!

  • Rena Johnson

    Thinner than I thought it would be. It fits well and is comfortable. The whole process was very quick too. Thanks

  • Meredith Wells

    Wasn’t sure whether I should go with an upper or lower guard. I chose the upper and when I got it I just couldn’t get used to it. I’ve never had to sleep with anything in my mouth and I found myself taking it out at night. I emailed the Sentinel team and told them my dilemma. They suggested I try a lower instead and voila! Feels so much better. I was most impressed that they really did work to my satisfaction and did it without sneaking in extra charges or hidden fees. Honest and good company. Thanks.

  • Jackie Harris

    Same one my dentist made for me. Absolutely no difference at all except the cost. Such a relief!

  • Laurie Moudry

    By far, the most comfortable night guards on the market. These guys take pride in their work and will work with you to your absolute satisfaction.
