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.

Product Reviews

  • Jane Barnhouse

    This night guard company was recommended by my dentist. This product works very well and it relieved my jaw pain very quickly. I use it almost every night, overnight, and sometimes during the day. I can feel it when I don’t use it! Results are great and the impression kit was straightforward. Turnaround time was quick. I highly recommend!!

  • Gigi

    I’ve had other nightguards before, but this is probably my favorite. t fits like a glove. It was easy to take the impression of my teeth, and I appreciate that they included an extra putty pock in case I messed up! I’m a picky person when it comes to anything I have to wear in my mouth so I’m pretty impressed with this nightguard.

  • Heather Dawn


    Dental night guard that fits great!


    They are the absolute best. I have been receiving dental night guards from Sentinel for the past 10 years. All of the staff are consistent professionals and the best in their field. I can’t recommend them enough!

  • Gail McCurn

    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.

  • Alex Silveira

    Wish I would have known about this service years ago. Got talked into paying $500 for this at my dentist. You guys have saved my smile and my pocketbook! Thank you <3

  • 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.

  • Emma Houser

    Sentinel is the best!!

    I’ll save you from a lot of wasted time. I’ve been a teeth grinder for many years. My jaw is a wreck. I’ve had dentist made guards, store bought guards, and I’ve tried other online labs.
    Sentinel is the ONLY company that has been able to help relieve my jaw pain. The Sentinel guards fits. it’s comfortable and durable. This is a high quality service and the best I’ve found. Save yourself time and money and go with Sentinel!!!

  • 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
