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.

Half the cost then my dentist is selling for the exact same product and same results.

The customer service of this company is wonderful. They’re a small, family owned business and I love that everything is made right here in the USA! I have a gluten allergy and learned that my dentist was using a Chinese lab to make his night guards and couldn’t verify the materials in it! I was able to order a gluten free mouth guard from Sentinel that fits perfectly and I couldn’t be happier! Excellent product and service!!
Nadar
I love my first night guard. Had some dental work done so ordering my second! I suffer from TMJ and this guard I wear for my lower teeth. It helps greatly with my jaw pain. No more popping and clicking since I started using it. The Sentinel team is fast, courteous and the product does the job at a price way lower than my dentist. Amazing!
Gina Cameron
I love my mouthguard that I ordered last year in August and unfortunately I cracked the back piece where my molar grinds down on the guard.
Sentinel sent me a free replacement. I received it so quickly and it fits perfectly. Thank you for taking care of your customers!

This product is the real deal!
I’m writing this review because I recently took my custom night guard that I received back in April to my dentist. I expected him to tell me that it was crap and that I needed to purchase a night guard through his office. Instead he said it was a very well made, great fitting guard. I’m very pleased with the high quality, commitment to safe products and the price! Keep up the good work!
ROXANNE
I LOVE the fit of this night guard! I had tried one from my dentist at a cost of $600. Wore it for 4 nights and threw it out. I tried the store bought guards with no luck. Figured I was out of options until I came across your website. Customer service was great at answering my questions and the guard fits FAR better than the others.

The guard I ordered a year ago is still good but I had some fillings on my back molars and that changed my bite so I’m reordering. Great product 😀

You guys have the best customer service. Hands down! I ordered from your company three years ago and just placed a second order. I can’t wait to receive my newest guard. Top notch everything!!
