LOVE my new guard and the commitment this company has to using safe ingredients. I had an allergic reaction after using one I bought from Walgreens, a boil & bite. I appreciate the transparency of the materials used. This is high quality and the fit is perfect!

An absolute tooth saver! I have the hard night guard for nighttime and just received this day guard. It’s a perfect fit. I love wearing it during the day and no one can tell I have it in! -Pam

Just placed an order for a second one to have as a backup. The fit is perfect! Thank you~

I didn’t realize how badly I was clenching my jaw during the day until I started having headaches! I work from home but on a computer for long periods of time. This works so well. The ordering process was easy. My headaches are GONE and I feel so much better knowing that even if I can’t stop clenching my jaw during the day, my teeth are protected! 5 stars!!

I found this to be perfect for so many reasons. 1st I found these to be so helpful when I realized I was suffering massive headaches during the day from clenching my teeth. I found the day guard and then later saw that they had other varieties as well. The 3mm hard night guard is perfect for my nighttime grinding and I wear the thinner day guard at work. Being able to have them both and save a lot of money is wonderful. I got 20% off my thicker nighttime guard because the lab already had my impression on file. All you have to do is ask for the coupon code! I highly recommend these!
Jason Cumbers
The communication was clear and helpful throughout the process. I would highly recommend this night guard company for anyone looking for a comfortable, affordable custom guard.
Keith Sell
These day guards are a good value. The other night guards are more to wear thru the night. The teeth impression shaped easily. I was happy to see they sent some extra putty in case I needed to redo it but I didn’t have to. Got a perfect fit. Day guard fits well and I’m a happy customer!

VERY COMFORTABLE
This is my honest review. I have crooked teeth and was very concerned about how this would fit over my teeth. I took a bad impression the first time around. The team at Sentinel sent me a new kit. They did not charge me for the 2nd kit. I took my time reading the instructions and got a good impression. I usually work about 7 to 8 hours at my computer per day. I wear this guard during the day and it works well. My jaw feels better. I feel good knowing I’m not doing damage to my teeth now. I bought 2 more of them during their xmas deal as backups. Go for it. I definitely recommend them.

Worth the investment!!
I was going back and forth with whether to order a whole, standard night guard or the no-show guard. I chose to get a no-show day guard and I’m so glad I did! My order came in much less time than expected, and the quality is outstanding. The cost is about 1/3 of what my dentist wanted to charge. I would definitely order again, and would recommend them highly.

Ever since learning that most other companies outsource the making of mouth guards to other countries, I’ve decided to stick with this US based company. They’re transparent about the safety of the plastics used and I feel confident in the quality of my mouth guard. -Kim

My dentist told me I needed to be wearing a night guard during the day for my teeth clenching but could only offer me one of the bulky ones he sold at his office. No thank you! I did a search and selected this company on the basis of all the positive reviews. No regrets! I have only positive things to say about my experience. I received the kit and read the instructions carefully.I sent in pictures of two molds I took and the company representative helped me decide which one to mail in. The guard came and fits so perfectly. I wear it all the time. This is my first day guard and it has worked successfully. I highly recommend this guard!
