Customer ratings & reviews

I like the Sentinel brand. I already have a night guard and I have referred my family to them over the years. The retainer is high quality and fits better than my old one. Mouth guard case could be higher quality but they did send me an extra one for free when mine broke.

My daughter needed a new retainer for her upper, hers didn't fit right, rubbed her gums, she wouldn't wear it and didn't want to go back because she wasn't heard when she expressed that something was off. Anyway, we had a new upper made by Sentinel and it fits perfect. So she's back to wearing them nightly again, and I don't have to worry about the investment we made in her smile being lost. So thank you again!

Worth it! Thank you Sentinel!

I bought this as an affordable option vs. going to get a customized piece from my dentist for triple the price. When I opened them I was immediately impressed with the quality. They're formed so well, comfortable, and they stay in place all night. Pleased!!

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!

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!

Be careful when taking your impression. They're very particular about making sure the impression is perfect. I had to redo mine. They did not charge me for the new kit they had to send out. Very happy with my retainers. They're cut and shaped with care. They fit like a glove. Just be sure to read all the instructions and capture all of your teeth evenly. Otherwise you'll have to redo it.

EXCELLENT!! I didn't get my impressions right the first time and I used up the extra putty. They sent me another kit free of charge! I sent in photos and they were accepted. Company has great customer care and the retainers fit like a dream!

Amazon Review 5.0 out of 5 stars Great Affordable Mouthguard Process was easy and normal shipping speed. I had trouble making good impressions but Sentinel Mouthguard's was able to send me new molding clay without extra cost. Fit beautifully. -L. Bryant
