Customer ratings & reviews

SURPRISINGLY EASY AND FAST I developed a mild teeth grinding problem and needed a night guard. After reading a couple of reviews, I felt comfortable ordering. The impression kit arrived super fast. I took my first impression but mixed the putty too fast. Luckily, the kit contained putty for a 2nd attempt. Nailed it on the second try. I emailed Sentinel to verify the quality of the impression before mailing it in. They responded very fast and ok'd it. Recieved the night guard and it fit like a glove. I've been wearing it regularly (my dentist will be proud). If you're wondering if this is the same quality product as the dental office that charges $500, yes it is! Thank you Sentinel Mouthguards

This mouth guard has helped my jaw tremendously! I could barely chew before wearing this. My jaw was so bad off I was making crunching sounds while I ate and had to chew softly. I'm still trying to be mindful of my eating but NOT due to pain from grinding and clenching. Thank you!

Wow! Just terrific customer experience all around. I received my night guard today and if fits perfectly. Thank you!!

My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It's a lifesaver! I can't sleep without it now! 5 stars and I'd give 10 if I could!

It took me quite a while to actually start wearing a night guard. I let my TMJ get so bad that I was experiencing a crunching sound in my jaw. I couldn't afford the ones from the dental office so decided to give this a try. I've had this guard now for a few weeks and my jaw feels SO MUCH BETTER. I have to wear it every night. There were a couple of nights I forgot to put it in and I felt it the next morning. Now, it's not completely gone. I still have some mild pain but nothing like what I was experiencing. With complete gratitude, thank you Sentinel.

Excellent product! A++++

Durable enough to handle my jaws and that's saying a lot! I have gone through so many of these but the material is strong and I love that they don't add any resins or acrylics. I'm sensitive to chemicals. This is the safest, best night guard I have found! A++++

I chose Sentinel Mouthguards largely because I've heard nothing but good things about their customer service. I'm happy to report that my experience was wonderful. They make it easy, fast and friendly! In this crazy world that we live in, I appreciate their extra effort to ensure that I am satisfied. Thank you Sentinel Mouthguards!!

These retainers are even better than the ones I received from my ortho! They're beautifully shaped and fit perfect. I lost my retainers and ortho was going to charge me an arm and a leg for a replacement set. Be careful taking your dental impressions. I had to redo mine the first time but they sent me a replacement kit for free! My advice is to watch the video a couple of times before you do it :) -Abby

I love this company as a whole. The front desk lady is so nice. I had a million questions before I ordered because I have a bad gag reflex and was worried about taking my impression. They are patient and kind! Answered all of my questions. The impression taking process was much easier than expected. Final product fit nice! A little snug at first (first few nights) but I adapted to it and I love it.
