Customer ratings & reviews

Just bought two more for my little cousins for Christmas. I've had mine for about 5 months now. I used to go through the $5 ones every week!

I received my mouth guard and am very happy with the product so far. It was a bit nerve racking finding an internet company to fulfill this need. I'm glad I found Sentinel. I have been telling everyone I know about it and I've found most of my friends and family have mouth guards. I will continue to talk about it and hope to send some folks your way.

Better than my ortho!! Impression process was easy. I love them! Customer service was very informative and friendly <3

Oh my gosh I saved so much money going this route! My dentist was going to charge me $500 A PIECE for new dental retainers after my dog chewed them. My teeth aligners are perfect. They fit so good. HIGHLY RECOMMEND!

This is a review about their customer service. This product just didn't work for me. I have a very bad gag reflex and was unable to use the trays to take my teeth impressions. I opened and used the impression kit they sent out and called them to tell them that I couldn't complete the process. They were so kind and issued my full refund immediately. Didn't even have to send back the materials! Even though I didn't end up getting a night guard, I was so pleased with the way they handled my issue. I will be back if I can ever get past this horrible gag reflex! Thank you again Sentinel. -Mary

Been wearing mine for a few weeks and it's been a life changer. My headaches and jaw soreness are gone! I've had many night guards through the dentist. I've paid a lot of money for these things. It's nice to find an affordable option that still has the high quality I need. Thank you!

I absolutely love it! My mouth feels so much relief and the customer service is spectacular. It is so much better than another company that I had tried previously. The fit is perfect for my mouth and I feel comfortable wearing it.

Not super comfy at first but really nice looking. I love that they are super low profile and the quality is great for the price. I totally recommend these.

Soft, thin and comfortable! A+++++

Love these retainers! I bought mine on Amazon and they are a better quality and better fit than my dentist. About to order your teeth whitening system too. Thank you for the great prices and service!
