Product Reviews

  • Desiree W.

    Ortho price is much higher and quality is the same Would recommend!

  • Chris A.

    This is my 2nd set of retainers from Sentinel. First set I got through Amazon. Communication is better when you buy directly from the Sentinel website. I understand after speaking with the customer service that they;re a third party seller on Amazon which means that you’re better off contacting them directly than going through the Amazon contact. They kept my teeth impressions in their file database and were able to make my 2nd set at a 20% discount. They fit just like the first. I’m very satisfied and will let others know about this great company.

  • John Feldman

    I recently lost my dental retainer. I only wear a top one so I didn’t need a lower one. Customer service said I could either order 2 top guards or get 20% off if I only wanted one. I ordered 2 top guards to be safe. I’m grateful I didn’t have to spend $500 at my orthodontist. Exactly as advertised.

  • M. Margowsky

    Upper retainer did not fit at first. Lower fit great. Contacted the company. They sent a new impression kit. This time I sent in a picture of my upper teeth to make sure it would work before I mailed it in. The 2nd guard fits much better. Customer service is helpful.

  • CM

    These are the best retainers I’ve had for fit and comfort.
    I have nothing but positives to say. Affordable, very well made and great customer service. *****

  • Michelle M.

    I almost never leave reviews but this is worth taking the time. The customer service is outstanding and helped ease my concerns about doing this online. The retainers themselves look SO MUCH BETTER than the ones made from my orthodontist. They technicians must be artists! Do yourself a favor and order from this company. You won’t regret it!

  • Darren J. Griffith

    I didn’t get a good impression of my back molars on my lower teeth (uppers were fine). The company quickly sent me a new kit explaining that I needed to retake my impression. I took my impression again and sent it off. Received my retainers about a week or so later. After wearing my retainers for a couple of weeks now I can say that I’m very happy with my decision. The price is much better than the dental office and I was impressed with the quality of their product and service. I will definitely be purchasing again when it comes time for a replacement.

  • Karen Cox

    Great service and great product! I replaced my retainers after my dog chewed up my old set. The old set cost me $450 from my orthodontist. The process was easy. The material feels very similar to my old ones. Maybe a little thinner? The scalloped top is different than my old ones. They were cut straight across but these do seem to fit better. Product is as advertised in the pictures. Would recommend!

  • Gail K.

    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.

  • John C. Smith

    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!

  • Lisa

    Worth it! Thank you Sentinel!

  • Douglas Reynolds

    Did not work for me. I couldn’t get the impressions right. We tried 3 times. Ended in a refund. Not upset, just not for me.
