Customer ratings & reviews

I rarely leave reviews or contact companies but I felt compelled to reach out and give my thanks. I'm on my 3rd nightguard from your company and I couldn't be happier. My dentist had been telling me for years that I was grinding and needed a nightguard. Like thousands of other Americans I promptly ignored him until I chipped a tiny bit off a molar due to grinding and realized I needed to get serious about this. I balked at the 500$ price my dentist wanted. I tried a store bought night guard which I carefully molded with boiling water per the instructions and then promptly threw in the trash after gagging on it all night. Then I found you guys and for a fraction of the dentist's price I received a custom molded night guard. The process was easy, the fit was great and now I can't sleep without the night-guard in...I feel naked without it. My morning headaches and jaw pain are nearly gone and I couldn't be happier. Keep on keeping on!

Thank you Sentinel! Guard fits great and I'm completely happy with the service.

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.

A great option for teeth grinding! I bought the boil & bite kind for years and they fit terribly. I was nervous about taking my dental impression. That was the big hesitation because I have a bad gag reflex. Talked to the lady on the phone and she walked me through the process. The fit is a world of difference and I couldn't be happier. If you're thinking about it, just do it. Well worth it.

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

Fits perfect! Thank you!!

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

They have a great product for a fraction of the cost that you’re dentist will charge. The customer service is outstanding, I had an issue and they took care of it immediately. They kept me informed during the entire process. I would recommend them to anyone.

Just wanted to say how IMPRESSED I am with the lower 2mm nightguard received. Over the years the price of night guards at the dentist office have been $400-$500 and my most recent quote was $798! The finished results at these facilities seemed less custom (even though an impression was taken). In addition, the appliances would require dremel-type grinding by the dentist on the actual appliance so that it would fit better in my mouth - I never expected that a nightguard from a mail-order could FIT LIKE A GLOVE, require no adjustments and feel so comfortable. I can even talk better with it in when compared to prior guards on my lower teeth. I do notice that after a week of use I have acquired a few minor rough spots on the guard from my obvious night grinding, so I hope that I have enough thickness, but that is not a complaint in the least. just a hope that I have the thickness is enough for me. Seems like there is always an option to go up in thickness if ever needed. A big THANK YOU for being an affordable and reliable resource in a time when dental and healthcare costs are soaring - I APPRECIATE YOU!

READ THE INSTRUCTIONS! I had high hopes of getting my teeth mold right the first time but I let the putty get too hard. The second time I hit the front of the tray with my teeth and distorted it. They sent me another kit with two more tries in it. This time, I read the instructions and watched the video and nailed it!! My night guard fits great and it is high quality. I have sent many of my family and friends to get their custom mouth guards. A++++
