Not all teeth grinding habits are the same. Heavy teeth grinding can wreak havoc on your smile and affect so much more than your quality of sleep. We understand the short and long term effects of heavy, chronic teeth grinding and clenching. Teeth wear, cracks, chips and sensitivity don’t just happen overnight but once it begins, costly dental repair is needed. This is why we created a durable mouth guard built to protect your smile.
Protecting Smiles, Wallets Too
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.
Our Durability Mouth Guard for Heavy Teeth Grinding is specifically designed to withstand intense teeth grinding and clenching, offering superior protection for even the most severe cases. Made from a strong, durable material, our mouth guard is engineered to absorb and distribute the force of your teeth grinding and clenching, protecting your teeth and jaw from the damaging effects of this common problem.
Experience the difference in just three simple steps:
Our simple and easy-to-use mold kit allows you to create a mold of your teeth from the comfort of your own home. Once we receive your mold, we’ll create a mouthguard that fits perfectly to your unique dental profile, ensuring maximum protection and comfort.
Say no to shortened, cracked teeth and hello to a healthy smile.

Best purchase I ever made 3 years ago and here I am again to order a new one! You guys are great!
Rick Meranus
Received my guard over the weekend and have only worn it a couple of nights but so far it’s amazing. Already feeling better! No headaches and my teeth are not hurting during the day anymore. I’ll update again after a couple of months to give some feedback on durability but so far so good.

I went through several online companies before finding yours. I had to return every single one of them for various reasons. Hands down best fitting guard I’ve ever worn. You guys are exceptional and have my business as long as I’m grinding my teeth! -Thomas

Would not hesitate to use this company again

This is my second purchase from this company courtesy of my dog chewing the last one. Before I found Sentinel, I had spent $500 on the same thing from the dentist.
Making one impression takes about 5 minutes from start to finish. You do have to take a second impression of your lower teeth too (also takes 5 min.) so allow about 20 minutes total to familiarize yourself with the instructions, etc.
Make sure you mix the two different color putties together quickly until they are one color, then you put it in the tray and press your teeth and you’re done! Mail it off and you have a mouth guard back in about a week. Very easy, and well worth the money.

I’m not a person who writes reviews but this company deserves a glowing one! After emailing Chasity with some questions, I felt comfortable placing my order. They make the molding process super easy to follow. I mailed the impressions back and within a week my new guard arrived. It was beautifully crafted and fits perfectly. The attention to detail is apparent. This is an exemplary company that I will be using from now on.
I love that this service is available and my teeth thank you!

Returning customer and I’m please with this replacement. I did have to take a new dental impression as I learned they only keep the impressions on file for 1 year. This replacement guard is just like the one I received several years ago. Consistent, good work. Thanks

AS GOOD AS MY DENTIST’S!
First try with the dental impression kit was unsuccessful but they include an extra packet of putty so I was able to get a nice teeth impression the second time around. I emailed the company a picture and they verified the impression was sufficient. Mailed it in and the mouth guard came about a week later. I am extremely impressed with the fit and quality. Just the same as my dentist only hundreds of dollars less!

My first time ordering from this brand. Impression kit came very quickly and included extra putty in case I needed it. The cost is worth it to be able to complete it from home without having to go to the dentist. The product fits very well and has really helped reduce my jaw pain.
Steven Daniels
Customer service is remarkable! I had ordered from another company and after messing up my impression, they tried to charge me $25 to send out another impression kit. Sentinel sent one for free. No questions asked. They’re fast, friendly and less expensive than the dentist. I highly recommend. *****

This mouth guard has helped my jaw tremendously! I could barely chew before wearing this. My jaw was so bad off I was making crunching sounds while I ate and had to chew softly.
I’m still trying to be mindful of my eating but NOT due to pain from grinding and clenching. Thank you!
Johnny S.
Durable enough to handle my jaws and that’s saying a lot! I have gone through so many of these but the material is strong and I love that they don’t add any resins or acrylics. I’m sensitive to chemicals. This is the safest, best night guard I have found! A++++
