So my dentist told me that I've developed a mild teeth grinding problem. AND my terrible insurance plan did NOT cover the required night guard that I was told I needed. Why? I still don't have a clear answer. But after some research online, I now have a custom night guard now that was hundreds less than what my dentist quoted me. It's a perfect fit. I even showed it to my dentist and he said it was fine! Umm okay?! Thank you Sentinel!

Beautifully made. I have to admit I was a bit skeptical in the beginning. It was a bit stiff and uncomfortable but then after a few nights it just seemed to loosen up and adjust to my mouth. For the price versus what my dentist wanted to charge me, I feel good about my purchase. It really is a nice mouthguard. I appreciate the extra attention to the shape. I've had mouth guards in the past that they cut straight across and even had jagged edges. This one is nicely done. Definitely worth it.

Glad I gave them a try! The fit was off when I received my lower guard. Upper fit perfect. They sent me a new impression kit and remade my lower retainer. Fits great! Happy with my purchase and would recommend. Suzanne in customer service is great!

A bit time consuming but worth it. The guards are a big upgrade from the ones I was using from Walmart. While it is a bit time consuming to have to make the molds then wait for the product to come, this is your best bet when compared to the cheap ones from the store. If you're looking for something with high quality but accessible price, this company is a good one.

Love it. Last time I went through a different seller and the quality was not half what yours is.I am very happy.thankyou

My most recent order is the second time that I have ordered from this company. They are sturdy, and very reliable. The reason for needing new ones is that my back molars grind so intensely at night that I ground through the first one. I think I ordered the first in 2017 so it did last me a while. I would highly recommend this product to anyone looking for a quality night guard.

I've tried several night guards from other companies and my best experience has been with Sentinel Mouthguards. High quality mouth guard and very responsive customer service. The guard arrived in a timely manner and fit good right out of the packaging.

Just like my dentist made guard but even better! Fits like a glove. I'm very pleased with the overall experience.

Perfect fit A+++

I was looking for a night guard that is BPA and gluten free. Customer service was very helpful and took care of my questions. Received the dental guard and have been using for a few weeks. So far, so good. Quality seems high. I'll edit my review if necessary. Edit 11/21/21 The guard showed a bit of wear and tear at about the 1 year mark. I called the company and they smoothed the molar area down for me for free. They said if I had worn all the way through it, they would replace it for free. But the smoothing those rough spots out made the guard like new again so I was happy.
