So easy to make the mold and fits like a glove!

This company has the patience of a saint because I was horrible at getting my impression right. After 3 different attempts I finally got a good impression. I felt so bad asking for another kit but the customer service was outstanding. The guard came and fit well. It did start to have lamination separation after about a month but I called and they sent me a replacement free of charge. I did not have to retake my impression (thank god). They keep them on file for 12 months. The 2nd guard is doing much better. Love the service! Will order again in the future.

Bought these for our both my husband and I and they are a hit! The shape is different from my previous guard but is nice and comfortable for sleeping. Shipping was quick and the customer service friendly.

This is it!! I have tried so many mouthguards by other companies and dentists. They always get it wrong. I expected the same this time but I was pleasantly surprised! The fit is perfect. Not too tight. Not too loose. It fits perfectly. I sleep all through the night. Thank you! You have a customer for life <3

I would agree with everyone below. Sentinel's customer service is #1. I received several emails throughout the process keeping me informed. I was thinking to myself another automated email system but they were all informative, useful emails with my tracking information etc. They are quick to respond through email as well and I received my night guard within about 3 weeks from the order date. *****

Messed up my impression the first time. Sent a picture in and they told me that it wouldn't make for a good night guard so I used the extra putty that was in the kit to try again. About 1 1/2 weeks later I received my guard. I'm glad they care enough to supply an extra putty pack for a retry and provide such friendly customer service. Will be back because I don't think this teeth grinding habit is going anywhere!

This is a quality product like you would get from a dentist. Thanks.

Great product! Great service! I totally recommend Sentinel!!
