Custom Soft Night Guard


Protect Your Teeth From the Grind

We understand the short and long term effects of teeth grinding and clenching (bruxism). Teeth wear, cracks, chips and sensitivity don’t just happen overnight but once it begins, costly dental repair is needed. That’s why we’ve designed a night guard that’s both effective and comfortable. Our Soft Custom-Fit Night Guard is made to fit your teeth like a glove, providing a secure fit that you’ll look forward to sleeping with. It’s so comfortable, you’ll forget you’re wearing it!

Saving your teeth and your pocketbook

Ask any dentist- there is simply nothing better to eat, laugh, talk and chew with than natural teeth. With Sentinel Mouthguards, your teeth are comfortably protected and your tooth structure stays preserved.

Your soft night guard won’t interfere with your speech or breathing, and it’s easy to clean and maintain. Plus, it’s free of BPA and other harmful chemicals so you can be sure you’re using the safest product available.

Product Reviews

  • 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!

  • Ana Veilleux

    Just wanted to say thank you for my great fitting mouth guard! I’m glad I chose the thicker one. I was worried it was going to be too bulky but it feels comfortable and I’m sleeping through the night.

  • 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!

  • Jing Zhang

    Best teeth guard I’ve ever worn! Slim design, light and fits like a glove! The one from my dentist didn’t compare to this one. Comes with a nice storage case as well. Thanks guys for an amazing product!

  • Jamey R

    Wow! Just terrific customer experience all around. I received my night guard today and if fits perfectly. Thank you!!

  • Dan C.

    Taking the mold of my teeth was a lot easier than I expected. The impression kit came to my house within just a few days of ordering. I watched the Youtube video and looked over the instructions that came in the box. Easy and straight forward. This process ended up being SO much less expensive than the dentist and I love how it fits and feels. I wear this while I’m lifting weights too. An extra perk!

  • Shawn West

    I used to buy one of the drugstore mouth guards every couple of months and I’d wear a hole through it in no time. This is not the case with these custom made ones. The quality of the plastic is higher and much more durable. Still less cost than the dental office versions. I will order from this company again. Best mouth guard ever!!

  • Melanie Jones

    These are custom made and fit like they are exactly for your teeth. They are thick enough to be durable for a heavy teeth grinder like myself and I was happy to learn that they are the safest night guard online. Staying away from BPA, MMA and Pthathlates is very important to me. They seem to keep the shape well as it’s been about 6 months since I ordered and still fits like a glove. I’ll update if something changes. I am using this for severe nighttime teeth grinding.I am very happy with this purchase and will be buying them again!.

  • T.H.

    In this review, I compared to OralB brand from Wal-Mart to Sentinel Mouthguards. Without a doubt, there shouldn’t even be a comparison. I didn’t know what I was missing and I don’t know why I took so long to switch to a custom made guard. I used to go through several of the Oral B’s from Walmart per year and I thought I was saving money.Oral B guard doesn’t stay in place, the material is cheap and if you grind through it oh well. My vote by far is for the Sentinel brand. I use the night guard everyday so cost and effectiveness are important.
