Customer ratings & reviews

I am a pretty heavy grinder at night and my previous mouth guards I bought from my dentist @ a few hundred dollars per (and it last 6 months),and a sports equipment place. These folks were referred to me in a casual conversation from a friend as we were talking grinding, then cost from a dentist, and I mentioned I refuse to pay that ludicrous cost any longer, so I went with a off the shelf football mouth piece (which is not good for nightly use I am told, and it tears up my mouth I have ordered 2 guards to date and they are the same if not better quality than the dentist. My first one lasted about 8 months.( a bit longer than the dentist) I am on month 3 of my second one.

Just as good as the ones they make in the dentist's office and much less expensive I am on my 3rd Sentinel mouth guard in about 3 years. I purchased mine directly from the Sentinel website. Wearing this night guard has almost completely cured the constant tooth pain I used to have due to teeth clenching while sleeping. While these are much less expensive than the ones from the dentist's office, they work just as well. The molding process is pretty easy but you have to be careful and follow instructions to get a good-fitting mold of your teeth. You also need to take care in cleaning the guard daily with some very mild soap and drying it well. My first 2 guards eventually discolored and stiffened up because I wasn't cleaning them right. The latest one has stayed soft and supple since I stopped trying to use fizzy denture cleaner type cleaners. I soak mine in CLEAR mouthwash for 30-60 minutes or so after I take it out, then wash with warm water and liquid castile soap.

I got my first night guard from my dentist for $400. When it wore out, they offered no discounts or replacements. This company not only offers a warranty on their night guards but if you're past the warranty, they give a 15% discount to returning customers. I am very pleased with my night guard but more importantly I'm pleased with the service. I am a customer for life!

Grinding was damaging my teeth and I could feel discomfort my incisors waking each morning. Wanting to have my natural teeth for many years to come I ordered this product after doing research on night guards. After receiving the custom fitted piece I was impress how it seated perfectly into place. I've ordered two different guards, the first was a lower guard which was a little less comfortable. I read that upper guards for many people are more comfortable so I ordered a second guard fitted for upper teeth. The upper guard is very comfortable to wear and I use it every night with absolutely no issues. From the very first use I knew it was protecting my teeth from damage and I no longer have discomfort from grinding. In addition to protecting against grinding I would imagine this guard is perfect to prevent teeth from migrating if one has a missing tooth. Teeth kind of drift if they aren't opposed on each side. I've recommended this protect to friends who have missing teeth to help keep their remaining teeth from drifting over time.

November 20, 2017 I’m honestly floored by how well the mouthpiece fits right out of the box. I have used grind guards for a few years for bruxism any to alignment, paid roughly $1000 a year and made more trips for adjustments than I could count. After getting this mouth piece, I don’t think I will be getting any more from my dentist. Molding was easy, and shipping was quick, even though it was the same time period as two big storms in Florida. Will definitely be ordering again!

This is one of the most comfortable night guards I have used. But most importantly is the outstanding customer service! Although an easy process to make the impression, I messed one of these up and Ashley at Sentinel was extremely helpful and sent another out. I ordered two of the harder material night guards, one for me and the other for my wife. After receiving the harder one, my wife preferred the softer material. I contacted Sentinel where they were quick to respond saying one will be made and sent out. So much easier (and less expensive) and convenient doing this at home vs. at the dentist. Highly recommend Sentinel.

This is a great service and though I had to do some work on my end to get the impression right, the squeeze is worth the juice! I was able to save hundreds of dollars and I'm very happy with my mouth guard. A+ Sentinel!

Great product and great customer service! If I can do this process, anyone can! The impression process was what I was most worried about and it was so easy. I don't usually write reviews often but this company deserves a mention. Sentinel goes above and beyond!

Wasn't sure what to expect but my guard is snug and comfy! I absolutely love this night guard and highly recommend!

Great value for the money!
