Customer ratings & reviews

I will admit I was nervous to purchase this after looking at the photos of how to take a teeth impression. It looked like it was something I could mess up quite easily. I ordered this because I grind my teeth and I’m now obsessed with Sentinel! I did mess up my impression the first time but it was because I was so nervous and should have waited until I felt comfortable but I went for it and mixed the putty too slowly. It hardened before I could even get it in my mouth! The company mailed me a retry kit free of charge. I was going to use this for just nighttime grinding but I use it during the day too. Which I can now say it works well for both day or night. All night guards will damage overtime so I know my double use is shortening its lifespan but with the prices (compared to the dental office) I'll just buy another one. Love it!

Unbelievable savings! My dentist quoted me at $650 for this exact same night guard! I took this to my hygienist just to confirm and even she said it's a well-made, high quality night guard. The fit is spot on! Grateful for your service that saves customers like me hundreds!

Due to the pandemic, my teeth grinding went from bad already to worse. I'm currently on my 2nd night guard from Sentinel. Ordered my first one back in 2017 and now in May 2021. This is a great value. The product is high quality and a great bang for your buck. Customer service is always outstanding!

LOVE! You must buy! Honestly so great. Fits perfect and good quality for the price.

Same as dentist. Thank you sentinel team!!

Love this service! I have been ordering mouthguards from Sentinel since 2013 and have never looked back! My dental office was charging me $700 for these hard guards. I'm a bad grinder and go through them quicker than most. Sentinel Mouthguards has great customer service and an even better product. Happy to be a faithful customer! I have and will continue to recommend this to friends & family. Sabrina C.

Easier than I thought! I was nervous about using this but the putty process was easy and they include a free putty pack in case you need to redo it (which I did need a 2nd try). I even called the customer service line and had them stay on the phone with me while I took the impression. They were terrific and very helpful. My guard fits beautifully. A+ service!! Will be back.

Wasn't to sure about doing this online but the cost difference between my dentist and going online was worth it to find out for me. This worked great! I'm very impressed with Sentinel, they were quick and affordable. Thanks!

After getting a guard through sentinel I now have a slight disdain for my dentist. He tried to charge me $520.00 for the same guard I just got for 135 through sentinel... what a joke. Awesome Price, Awesome Guard!

At first I bought night guards from Proteeth but these are much better. A few things to note: 1. Don't remove the putty from the tray after impression has been taken. Keep it in the plastic tray & mail the whole thing back. 2. Mix the putty fast. I mixed too slow the 1st time & had to redo. They included an extra putty set so it wasn't a problem. 3. They offer free adjustments if its too tight. Really impressed with this product, incredibly easy to follow instructions and if you follow them, you're left with a secure fitting, comfortable and perhaps most importantly a better nights' sleep. I know another reviewer was worried that reboiling wouldn't be effective since they might be similar to other mouth guard brands. That is true. You cannot boil the Sentinel Mouthguard. However, if you take your mold correctly you will not need to do anything but wear it. It wasn't the most comfortable process but worked.
