  1. :

    Exactly what I needed! Thank you so much! -Heidi

  2. :

    This turned out to be the best thing ever! I was able to make custom dental impressions for both sets of my teeth and received my set of retainers about two weeks after mailing the impressions back. The fit is outstanding & Sentinels customer service is amazing. I got such prompt response and their absolute concern for my health and safety was nice to see.

  3. :

    I was looking at paying $600 for replacement dental retainers after my dog chewed them up. I am grateful to have found your service! The impression process was easy. I thought I might gag on the impression substance because at the dentist they used a messy, goopy mixture that fell to the back of my throat but luckily the impression substance sent to me was not like that at all. The girl on the phone said it is similar to playdoh and that is exactly right. Even smelled like mint! I just wanted to let you all know that I appreciate this service being available online and if my dog ever gets a hold of my new retainers again I will be back!

  4. :

    Excellent quality and superior customer service. They fit better than my dentists!

  5. :

    Took less than 4 weeks total from start to finish. I wish it was a bit quicker because I had a fear of my teeth shifting but nothing had changed and the guards arrived and fit perfectly. These are $300 at my dentist so I guess I’m willing to wait a bit to save the money.

  6. (verified owner):

    This was a replacement retainer for another I had from a dentist which wore out in a year and a half. The Sentinel retainer fits very well, is thinner even than the old one and the price more affordable. Customer service was excellent – the first retainer I received did not fit perfectly so I contacted them via Live Chat and response was timely and helpful. Sentinel recast another retainer and also sent another dental impression kit in case the new one didn’t fit. Well, the recast retainer fit just fine so no need to do another impression. When Sentinel says they stand behind their product and want the client to be 100% satisfied, they follow through!

  7. :

    Teeth molds were easy to take and the staff is incredibly responsive. I had a lot of questions about taking my molds of my teeth but the staff was patient with me and guided me through it. My retainers came back within about 1 1/2 weeks after sending off the molds. If I ever want or need new retainers I will go through this company again.

  8. :

    Really liking these. My teeth are so sensitive now that my braces are off so I was hesitant to try this product. After reading the reviews I decided to try. This is a perfect option for me. The clear retainers fit perfect. No sensitivity and I’m loving the price!

  9. :

    Never thought I would be able to buy dental retainers online! So nice to not have to deal with my dentist again now that my teeth are straight. I just want to keep them this way and I also grind my teeth at night so it is comforting to know that I can reorder these if I grind through them because they keep my dental impressions on file. Sweet!

  10. :

    I absolutely love this product. I recently had to switch to the hard dental retainers because I made a mistake when I ordered and bought upper and lower soft night guards instead. Much to my disappointment, the soft night guards arrived and obviously did not help keep my teeth straight. I contacted Sentinel Mouthguards and explained the error.

    Customer service was excellent and the lab very quickly made my hard dental retainers and mailed them to me within a few days.

    They fit perfectly. They’re made extremely well. I wear them during the day & night. Very satisfied customer!!

  11. :

    Bought these for my daughter. Nice customer service and nice product. Very easy to work with and at a fraction of the dental office cost. I’ll take it 😀

  12. :

    This is going to sound like it’s not written by a customer but it is and I am a VERY HAPPY CUSTOMER. This may be the best purchase I have found. I’ve lost 3 sets of dental retainers and my mom was the one having to pay to replace them through the dentist. Well, I just ordered my second set of Sentinel retainers. Not because I lost these (not yet) but because I wanted a back-up ready just in case the inevitable happens and because they’re realistically priced/affordable I can pay for these on my own. A+++++

  13. :

    I spent over $500 from my FSA account to have my final custom dental retainers made by my dentist. They fit perfectly, but apparently I grind my teeth too and had to get them replaced. There was no option from the dental office given except to order another set for $500. Umm… no! After reading the rave reviews for the Sentinel Mouthguards on Amazon, I decided to give them a try. I must say that I am extremely pleased and highly recommend them. The directions were easy to follow, I created a great fit myself. Not to mention that it saves me $360! I’m never bothering to order another set of retainers from the dental office. Literally saved me hundreds. Thank you!!

  14. :

    I wanted to write this review because my experience has exceeded my expectations. I have been wearing my dental retainers for 9 months and I also grind my teeth at night and ended up doing some damage to the retainers. I contacted Sentinel and they asked me to upload a picture to their email of the wear on the retainer. They still had my impressions on file and made me new dental retainers because I was still within my 1 year warranty. I don’t know of any other dental office or lab that would do that. They paid for the shipping and everything. I am impressed with the level of quality of the product, the customer service and the willingness to back up the warranty. Impressive and refreshing company.

  15. :

    I am not the type to write reviews but this product is outstanding and really works as advertised. Highly recommend to anyone who needs to keep their teeth straight after braces but not willing to pay the dentist’ price! Will be buying again if needed.

  16. :

    Great quality and great company! I was so happy when my retainers finally arrived to my door! I wasn’t sure if my impressions were going to be good enough so I emailed a couple of pictures of the impressions and they said it was best to send new impression kits to me to retake them. I got it right the second time and received my retainers yesterday! The fit is perfect. Thank you!

  17. :

    Better quality than what I got at my dental office. I would definitely recommend Sentinel Mouthguards to family and friends. I am very pleased with the fit of the product and customer service.

  18. :

    It’s like the dentist ones. Pleased with the fit. I ordered the teeth whitening too and will review the whitening once results are in.

  19. :

    Excellent fit and highly recommended! The process is easy. I was a bit wary about ordering online but after reading the reviews on this company I decided to give it a try. Great all around! Thanks Sentinel Team!

  20. :

    I can’t say enough good things about this product and the companies customer service.
    The secret to getting a good fit is to read the instructions carefully and make sure that you submerge all of your teeth including the gum area evenly and do not remove until your 3 minutes is up! I had to learn this the hard way but the company sent me new impression kits at no cost! Second attempt worked! Very responsive and easy to work with. The guards felt a little tight on my teeth at first but became comfortable after a few nights.
