Customer ratings & reviews

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.

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!

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.

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.

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!!

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+++++

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 :D

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!!

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!

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!
