Customer ratings & reviews

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!

I've ordered from other companies and these are simply the best. I've been with Sentinel since 2014 and they have stayed consistent and good.

Got this for my wife. She loves it. Says her tension headaches are not there anymore. Took some initial getting used to but she adapted and loves it. 5 stars!!!

I love my mouthguard from Sentinel. It is very comfortable, and I can't sleep without it. I like that you can choose the thickness as well. It's super convenient that they hold onto the mold so I can reorder when needed without having to make a new mold (although it is a very simple process to make the mold). I highly recommend Sentinel mouth guards.

Easy fitting process and very comfortable to wear. Sentinel's delivery was a little late, although the Company sent me two soft night guards for the price of one. Would definitely purchase again and recommend to my friends and relatives.

Excellent value. Fitting was easy. Just follow the instructions. The night guard arrived promptly and fit perfectly. Took a few nights to get used to wearing it, but now it's the first thing I look for when I go to bed. I purchased a second one to use for traveling.

Purchased several mouthguards over the years from Sentinal and aways been happy with the products and the service. Thank you! Ben

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.

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!

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.
