Product Reviews

  • Tony Brown

    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!!

  • Letricia Morrison

    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!

  • Karena Powell

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

  • Paul Johnson

    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!

  • Emily Baker

    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.

  • BK


    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!

  • L. Bryant

    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

  • Cameron DeLouse

    These retainers fit great. I ordered 2 lowers for the same price as the upper and lower. My ones’ through my orthodontist were cut straight across. These are cut very nicely and fit much better!

  • Sterling Carlisle

    The only lab I’ll buy from. I’m reviewing the dental retainers but my husband has a night guard from Sentinel lab. We’re both over the moon about the savings and the quality of the products. Have recommended to many friends and family. Consistent, great service all around.

  • Ayanna B.

    Love love love! Took a couple of days to break them in but now I’m wearing them all the time. I talk with them in during the day. Totally worth it for me.

  • Jessica P.

    Perfect Fit! *****
    Easy to use process. Nice quality and very good replacements I hope this product last.

  • Kristine Paul

    I was afraid these weren’t going to work for me because the ones my dentist made for me were uncomfortable but these popped in and fit perfect. Comfortable and very high quality.
