Customer ratings & reviews

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.

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++++

Excellent product! 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.

Okay here is my experience with Sentinel Mouthguards: The process is easy but you have to pay attention to the impression instructions. I failed my first two attempts because I mixed the putty for too long the first time and the second time I distorted the impression because I moved the tray around while it was in my mouth. Both times were admittedly my fault but I was still frustrated at the time it happened. The customer service is excellent. They were prompt and friendly. Sent me a new kit with no charge. I got a great impression of my teeth. Waited about a week and 1/2 and sure enough my mouth guard came. It comes in a black retainer case. I tried it in and it fit well. Took me a few nights to get used to it but the quality is great and I saved so much money going the online route instead of my dentist. Not to mention the hassle of driving back and forth. I wear mine nightly. I called and they gave me some cleaning instructions. Pretty simple. Use a mild soap and a soft toothbrush. Make sure you rinse it well and dry it completely. This will prevent yellowing. I'm already seeing a few grind marks on the guard but better on the guard than my teeth grinding together! Overall, I highly recommend Sentinel Mouthguards. The experience was impressive and quick.

THEY'RE PERFECT! I travel a lot for work, so the fact that I can pop my clear dental retainers in and out easily is a game changer. Plus, they're comfortable to wear for extended periods of time. I don't have to worry about any discomfort while working long hours
