Customer ratings & reviews

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

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.

AMAZING TO WEAR NIGHT AND DAY!! Great product! I definitely recommend this to anyone looking for a high quality retainer without the high cost. Easy to wear. I wear this pretty much all the time except when I'm eating or drinking. I want another one for travel!

Quality retainers, great customer service and very affordable. They give extra putty if you need it. Great value for the money!

I have a small mouth and needed small tray sizes sent out. Sentinel was very accomodating. Made the initial purchase 3 weeks ago and I already have the custom retainers. This company will be my go to whenever I need to replace my retainers in the future.

Fits like a glove! Just needed an upper. I have a permanent lingual bar. Taking my impression was fine. Make sure you take a deep impression because the gum area does need to be there. I highly recommend!!

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.

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!

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.

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.
