Customer ratings & reviews

We are huge fans! My mother needed a few attempts with the impressions, as it was difficult with her arthritic hands, and they were so patient and lovely about it. After a few back-and-forths we now have a PERFECT fit! We also required a custom size of 1.5mm for dual-laminate, versus the standard 2mm, so don't hesitate to ask if you think 2mm might be too thick. Ashely was such a pleasure to work with, and a very fast response time.

This is going to sound like it's not written by a customer but it is and I am a VERY HAPPY CUSTOMER. This may be the best purchase I have found. I've lost 3 sets of dental retainers and my mom was the one having to pay to replace them through the dentist. Well, I just ordered my second set of Sentinel retainers. Not because I lost these (not yet) but because I wanted a back-up ready just in case the inevitable happens and because they're realistically priced/affordable I can pay for these on my own. A+++++

Great product, not too bulky. Way less than the dentist. Happy customer!

I LOVE Sentinel mouth guards! I've been ordering from this company for at least 5-6 years. Always quality products, wonderful service, and especially unbelievably great prices! Don't pay the dentists' high prices - buy from Sentinel and save money for the exact same thing your dentist makes - at a fraction of the cost!

I've had my Sentinel Night Guard since last July after the clicking in my jaw increased and it started to become painful opening my mouth all the way open; also was doing some pretty bad grinding. Although there was a hiccup of my order being processed in the listed timeframe, Sentinel was able to fix the error and rush the turnaround and get my night guard back to me pretty quickly. It has worked wonders and drastically decreased my clicking jaw and wear/tear on my teeth.

I just received my 2mm soft night guard in the mail, and it is a perfect fit! As mentioned in other reviews, taking the impression was much easier than I thought, anyone with silly putty experience as a child can do this. After having paid my dentist > $600 for thses things in the past, I cannot ever imagine going anywhere else than Sentinel for these guards in the future.

The process of creating your own mold is so simple and easy to execute at home. Unfortunately, my dog ate my first guard but ordering a replacement has been a breeze. Thanks for an affordable and quality product!!

I have spent a small fortune on mouth guards at Dick's sporting goods. I've tried all kinds of different brands. Some are decent but the problem is, none of them last. I end up replacing them after a few months. This guard is the real deal. I don't chew on this one (which is a first for me) because the material is not as soft as the ones you buy at Dick's and it stays in place so it's not hanging down. I like that Sentinel keeps my mold on file so that I can reorder in the future. Really nice guard and good price. I will recommend them to anyone.

I grind my teeth at night and in the day and I've worn through many night guards. This is the best one I've ever had, and it has cost me the least. I've had it for several years now and it hasn't cracked, discolored or changed shape. I still have my wisdom teeth and Sentinel was able to get me a mouthguard that covered those as well. I like the night guard is clear, too. It's easy to leave in Efferdent all day, daily, and it looks obviously clean. It still looks the same as the day I got it and it has definitely saved my teeth from cracking. I also like that the 2mm one is still fairly thin and I can fit it in my mouth. It doesn't force my lips open at night. I've also been very happy with Sentinel's customer service. They replied to me quickly and made sure that I was happy with my product. I plan to order more from them again.

Dentist made mouth guard might be good but at $600 I don't think so. After doing some research, I chose Sentinel because of their excellent reviews and the warranty they offer. Sentinel did not disappoint. At a 1/3 of the cost, the experience was quick, easy and pain-free! I love the feel of the soft mouth guard. It's thin and comfortable and fits my teeth like a glove!
