When something is good, you stick with it. This is my 3rd order from you guys. I've been grinding my teeth since I was little and this holds up better than any of the ones my dentist made. Thank you for an outstanding product.

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!

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!

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.

Product works great! It comes with a nice storage case. Definitely recommend!

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

I love this guard. It fits perfectly. I can't sleep without it and it's helped my TMJ tremendously. Thank you! -Arthur

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!

Spoke with Alexandra and she was very helpful and recommend that a ask for some extra putty!!

Better than my dentist! A+++
