Product Reviews

    I bought this on Amazon originally and have been a customer ever since. Great find and the price is right. Wearing a night guard has helped me tremendously.Instead of waking up with my jaw screaming at me, I just wake up like a normal person now. I do have to wear mine nightly and notice that the jaw pain starts creeping back up on me if I’m not consistent. The teeth impression kit is straight forward and they give you an extra putty if you mess up.

    Although my first guard didn’t fit right, Sentinel was quick to make me a free replacement and it fit perfectly. I didn’t mind the hiccup because I literally saved hundreds of dollars by not going through my dentist. Easy to get used to wearing and I love their attention to customer care!

  • Omar Willets

    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.

    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

  • R.J.

    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!

  • Sandra Rubio

    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.

    EXCELLENT QUALITY AND GREAT ALTERNATIVE TO THE DENTIST!!

  • Kristy D.

    Much less expensive than the dentist yet seems to be the same quality. Headaches and jaw pain have gone away! Easy set up.They provide you with simple instructions. I recommend!

  • Lance Gilchrist

    This mouth guard is amazing. I grind my teeth very heavily during both the day and night though I think I’m clenching more during the day. Brought this into my dentist appointment assuming he was going to tell me it was no good and to buy his $800 mouth guard from his office. He looked at it both in and out of my mouth and said it’s a “very well made guard.” I’ve tried many store brand mouth guards and bit right through those within months. Sentinel will be my go-to brand from now on.
