Customer ratings & reviews

Quality product! I was looking for something comparable to what my dentist was trying to sell me but without paying $600. I did my research and settled on Sentinel. What brought me to Sentinel after reviewing other online companies is their transparency in the materials that they use, they're a US based company and they've been making custom mouth guards for many years. I'm glad I trusted them to make my custom night guard. The care and attention to detail is magnificent! The fit is great. Process was easy. I couldn't be happier. If you're on the fence, choose Sentinel! You won't be disappointed!

I wish I'd bought a Sentinel guard years ago. I had been using the boil n bites and they were always too big for my mouth. I felt like I chewed on those more! This type is hard so I can't chew on it. It's so slim and comfortable. A world of difference for me. I will update this review to speak on the longevity but for now, a huge thank you!

I have been wearing night guards for 30 years and this is by far the most comfortable one I've ever worn. The fitting kit was easy enough to manage. Turnaround was quick! Amazing! Thank you so much.

Process was easy, fast and straight forward. Plus, I saved about $500, Couldn't be happier with Sentinel Mouthguards. I have already recommended this service to several friends and family members. Great experience!

I value good companies more than ever these days. When you call, someone picks up. Friendly, fast process. The delivery of both items (the impression kit and the custom night guard) were correct and on time. Free shipping too! I'm impressed!

I bought this on Amazon and I'm so impressed by this company. My teeth impression kit was delivered within 1 day (granted I do have Amazon Prime). I took the impression, mailed it off and just a few days later, I received my custom made night guard. High quality product, fits like a glove and FAST DELIVERY. I would highly recommend Sentinel Mouthguards.

PERFECT FOR DAYTIME USE Teeth impression process was easier than I thought and I received my mouthguard very quickly after sending it off. If you're like me and clench your teeth during the day, this is the mouthguard for you! I love the fit of it. I love that I can communicate easily. I do take it out when I eat and drink. My headaches and jaw pain are gone and I can feel that my teeth are thankful I'm not clenching down constantly! A lifesaver for business professionals.

I typically never leave reviews but as this product does require some back and forth transactions I do feel compelled to leave some feedback. First, in full admittance, I was nervous about taking my dental impression. The company goes above and beyond to give detailed instructions including written ones as well as two separate videos. You don't have to utilize all of the instruction (the written ones are probably enough) but if you're like me and want to make sure you thoroughly understand what you're doing, the information is there and I did appreciate that. I had no problem making my upper dental impression but my lower one didn't come out well. Luckily, the company included 2 extra putty packs for additional attempts. I sent my impressions off and received the custom night guard within a weeks' time. The fit is much better than any other night guard I have ever worn. I am over the moon with the comfort and feel of this night guard. Overall, this service is wonderful. Email communication was prompt and friendly. I would highly recommend Sentinel Mouthguards to anyone considering a custom night guard for teeth grinding.

I wasn't sure how this would work but my cheek biting problem had gotten so severe that I could barely stand to eat or drink anything. Painful is an understatement. I checked with my dentist first and he had never heard of these. Hesitant, I went forward with my purchase. The impression molds were easier than expected. I sent them in and received my custom cheek biting guards within about 7 days. They fit like a glove and more importantly they work!! My teeth cannot do damage to my cheek area and after months of being in excruciating pain, my area is healed. I highly recommend to anyone with my problem. I don't think there's anything else like this on the market.

My mouth guard was delivered last week. I've been wearing it every night and my morning headaches and sore jaw are gone! I'm amazed out how easy it has been to get used to sleeping with it in every night. I used to wear a cheap one from CVS and I dreaded putting it in. The custom molding makes all the difference. Anyway, just wanted to say THANK YOU!
