Customer ratings & reviews

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.

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.

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

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.

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.

Are we able to give 6 stars?? I had bought twice previously, this time I wanted a change in thickness. They were so professional, working with me through discussing if the thickness upgrade would be a better fit for me. I’m very pleased with it. The quality is superb. I frequently grind my teeth and can notice a major difference when I wake up after wearing my night guard. Well worth the price.BTW if you are shopping for night guards, this is the only company I have found that offers so many different options as far as thickness and material type goes. I love that they seem to truly care about making sure I love my product. Highly recommend. Thank you

I've had mine for about 6 months. I would recommend these to anyone! Except maybe someone who has never worn one before as the 3mm is thicker but more durable than the 2mm. I've had both and I prefer the 3mm because I'm a heavy clencher. Make sure you're cleaning it well. My other one (2mm one) turned yellow after a while so I'm taking good care of this new one.

Great Night Guard, Read the Instructions! This is probably one of the best night guards for me that I've used thus far. I purchased this to help with my teeth grinding, but have found it extremely helpful for snoring too. I'm satisfied with the product and will order another when the time comes. Thank you!

I grind my teeth bad. My jaw can go from feeling awful to okay depending on the day or week.Even with pretty uncomfortable jaw pain, I still refused to wear a night guard. This went on for years. When I started getting sharp pains behind my eye I knew I had to do something. I tried the store bought ones. Waste of money. The Sentinel guard felt tight at first but now I'm used to it. My headaches and jaw pain are GONE! I wear it every night. It's truly made my life better. I feel younger strangely. Not in pain and grumpy. Thank you for making a life changing product Sentinel! I'm a customer for life.

My dentist had been recommending a night guard for my teeth grinding but I couldn't spend the money. Finally it got to the point where my teeth were wearing down, jaw was aching so bad, and I had headaches almost every morning. I found Sentinel online and the price is inexpensive compared to the dentist. I was sent a kit with the putty mixture and an extra set of putty in case needed. I took the impressions. FYI they make you take an upper and lower to check the bite before shipment. It took about a week and a half after I sent the impressions off to receive my night guard. It took me a few nights to get used to it but now I can't sleep without it! Wish I could give more than 5 stars. Excellent experience. Love that this is available to us as an affordable option.
