Customer ratings & reviews

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!

Solid product! 5 stars! Highly recommend!

Fast delivery Love my custom trays! I whiten during the day and no one even notices. A++++

100% Satisfied Customer!! I've been through so much with my jaw. Popping, pain while eating, teeth sensitivity..it was dominating my life but I couldn't afford the dentist made ones. I opted to go with Sentinel Mouthguards and I couldn't be more pleased. The mouth guard fits beautifully and my pain is GONE! You guys are serious life savers.

They sent me the impression trays and putty, and I chose the correct tray size. The smallest tray was too small and cut off my molars. Took my impressions and mailed it off. The teeth guards arrived within 10 days. I popped them in and they both fit like a glove. It works GREAT and I have no soreness. I'm 69 and thought I would never get used to wearing these. I am keeping this product as I am very satisfied.

The fitting process was quick and easy and didn't take long for the custom night guard to arrive (approximately 3 weeks from start to finish). Upon first wear, I was in shock at the positive difference! My first night went smoother and I felt like I got better sleep & zero soreness upon waking. This company will even keep your teeth impression on file for future orders which is a major plus. Thank you Sentinel!

This is a really good deal. My dental office wanted to charge me $400 for the teeth whitening. Found the same thing here for $150. The Zoom whitening gel lasts a really long time. You only need a little bit each time you apply it so 3 syringes lasts forever! Well worth it.
