Customer ratings & reviews

The product fits great! I've slept with it for about a week now and so far so good. I do bite my cheeks a little but I'm mainly using these as teeth protectors for my grinding and clenching. I'm hoping they hold up over time because they are soft and a little flimsy.

Tip from a customer who learned the hard way! Don't bite down into the putty. Keep your mouth relaxed and press the putty filled tray into your teeth evenly. After 3 tries I finally got it right! The sentinel team was gracious and gave me two free kits. Best company ever! My mouth guard fits perfect and my jaw feels so much better. No more popping and clicking!

Great service which has saved us a lot of time. Very quick and good communication throughout. Thank you.

Drink coffee? Smoke? Like soda? Then you should use this stuff. I have bad habits but you can't tell since I got my own custom mouth tray. Shit is bad arse!

Can’t believe I’m writing a product review for my tongue biting problem. But here goes. This is the most comfortable mouth guard set I’ve ever worn ever. I am so impressed by this brand. The customer service was extremely helpful over the phone. The entire process was quick and easy and the mouth guards are a perfect fit. This is a wonderful product!

My daughter got a custom bite guard from a dentist before. He took a mold of her teeth just like this. As far as I can tell, the only difference was that it cost more to get the bite guard from the doctor. This product is working great. Prompt, hassle- free delivery.

So first of all, this was super easy to take the impressions. All you have to do is mix the putty, place it in the tray and then slide the tray into the mouth. Push the putty up into the teeth and wait. It will get hard and may feel tough to pull out. Don't panic. Just use more fingers to "pop" it off the teeth. A tip for putting the tray with putty into the mouth: have a timer on hand and stand in front of a mirror so you can see what you're doing. It took me two attempts. This may sound confusing, but make sense when you are assembling it. Okay! The actual guard itself! It has really nice material & the shaping is well done. One piece in the front was a bit loose, but otherwise feels great. I’ve never had real quality guards so I can’t really compare it, but it seems sturdy.. I guess time will tell. I do wish the guard was a different color (it's clear) because I just don't want to misplace it..Now, the biggest concern for me is the comfort and they got that right. 5 stars!

Great customer service. Excellent product! Chose the hard dental guard at first and switched to this dual laminated type because the hard felt a little too tight on my teeth. The soft inside lining of the dual makes the night guard very comfortable to wear. Only night guard I've ever been able to sleep with comfortably. Thanks for working with me Sentinel team.

This mouthguard is so comfortable. The quality of material is great. It's flexible, bendy, light weight and the product fit perfectly well to my imperfect teeth. I've tried the store bought types. It's hard for me to find my size because of my crooked teeth. This custom option is a perfect fit. I've told so many people about you guys you should pay me for advertising your brand????

Saw that this site was mentioned on Reddit as a good place to get a night guard so I decided to give it a try. Very, very, glad I did! Saved me 500 bucks! I've sent some friends this way too and they were all happy as well. Thanks a ton!
