Customer ratings & reviews

I've had my guard for a couple of years and it still works for me.... I am a HEAVY grinder!!! Super comfortable, has held it's shape perfectly, perfect fit. I will be ordering another one soon, just because I want to have a back up. Amazing product, for real. Incredible price, incredible product.

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.

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.

This is by far the best mouth guard I’ve ever owned! I bought one from my dentist last for 3 times the price and 1/2 the quality of Sentinel mouth guard! It lasted less than 6 months. I like to use the product I buy before I leave a review and I have used this one! Every night for the last 2 years and occasionally during the day if I’m grinding my teeth due to stress. I have the dual guard that is just starting to show enough wear that I need to replace it. I will never use any other mouth! Sentinel is the best!

Thank you for your comfortable dual laminated night guard and fabulous customer service with Ashley. I once spent $700 for a TMJ splint that lasted less than 2 years. When it cracked in half, I freaked! Then I found Sentinel Mouthguards online and was so relieved that I could get a professional custom-made nightguard for $129! Great deal and a good quality product. I took it to my dentist to check the fit and he approved! He said even HE grinds his teeth at night! (I recommended Sentinel. LOL!) Taking the impression was so easy and it's great knowing they can make a future guard from my impression. As far as customer service, they really stand by their product. When my first night guard split after only a year, they honored their guarantee and sent me another. What can I say other than you guys ROCK! I'm so thankful that you're here. I couldn't live without my Sentinel Mouth Guard!

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.

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!
