Customer ratings & reviews

Surprisingly easy and fast! I lost my night guard and was in a panic. I didn't want to wait but dental office price is out of my budget. I paid extra for the expedited shipping (still way cheaper than the dentist). Got my kit within 2 days. Got my guard within a week of sending it off. Fits like a glove! So thankful for this company!

Excellent value for the money. I was pleasantly surprised with how easy it was to take my impression. I remember the dental office impression process being messy but this was easy and straightforward. I honestly can't believe how well the night guard is working out. My dentist charges over $500 for a device similar to this one. So pleased with Sentinel!

Perfect fit! I purchased my first night guard kit from Sentinel a couple of years ago. After 2 years, it had loosened up on me so it was time to purchase another. Consistently good! The second one is just like the first. This is a very well made product and much less expensive than the dentist. Highly recommend!

It was super easy to mold to my mouth. I read the directions and practiced with the empty tray before I begin (called customer service and that was a tip they had). The guard itself fit snug the first night but not uncomfortable. I was able to sleep no problem. I woke up with no jaw pain or headache. The relief literally came after one night of use. I've now worn it several times and it seems to be forming even better to my mouth. My dentist told me to purchase one from Sentinel because they're the exact same thing his office would offer but cheaper. Highly, highly recommend this product!

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!
