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.

The process was smooth and I received my night guard for teeth grinding quickly. So far, my jaw feels much better and my headaches are not as frequent in the morning. I think I may need one for daytime too. Ugh!
Either way, at least these are way more affordable than my dentist!
Nicholas Cook
So glad they started offering the 3mm night guard. I grind so badly that my teeth were wearing through the 2mm hard guard. I’ve had this one for 8 months now and so far so good!
Sentinel customer
Excellent product. Works exactly as advertised. I can breath easier, drink and even speak clearly. But even better is that it took us 3 attempts to mold the impression correctly and each time, Sentinel was patient with us and helped us until we got it right. Remarkable product. And let me add that my wife and I have had many of these from the dentist over the years. These are just as durable.

I was looking for a safe mouth guard and researched heavily. I asked several companies what was in their materials that they use and most were either vague or didn’t respond. This was the only company that I found that was willing to be transparent about the products they use.
I did confirm that the plastic is BPA free which was my main concern. The night guard took many nights to get used to but I finally enjoy wearing it. Thank you for being a reputable company. -Alicia

Top notch service and outstanding, high quality product! I love your night guards and they have saved my life! I was spending so much unnecessary money at the dental office and then when I couldn’t afford that, I went to the drugstore options. Ugh! So happy that you have an affordable option that LASTS! Love you guys!

I got this for my elderly mother because she grinds her teeth VERY badly at night. Her mouth is tiny, and since the process requires taking a teeth impression, I asked for extra material. Getting the teeth impression on her tiny mouth was a little difficult but only because again, small mouth. It molds and hardens very quickly. in a matter of 2 minutes, so it may take a couple of tries to get it perfect, but overall it’s easy to use, and has easy directions. She says the mouth guard fits her well. A good purchase for the money in my opinion.

Great product, not too bulky. Way less than the dentist. Happy customer!
