Customer ratings & reviews

The communication was excellent, and the turnaround time was very fast. I would highly recommend this company for anyone looking for a reliable night guard provider.

Love Sentinel Mouthguard products. This one has protected my teeth longer than the one my dentist made me. -CK

The process was easy and straightforward, and customer service was patient and helpful in answering any questions. I received my mouthguard and the fit is flawless. Excellent experience!

WOWZA! These mouthguards put all other mouthguards to shame! How can they fit so good, yet so inexpensive compared to my dentist? And comes with a 1 year warranty! Best night guard I've ever had. Literally obsessed with how good this fits. <3

The sentinel team was very responsive to my needs even after I messed up my dental impression. They provided me with great feedback throughout the process and I was able to take a great impression with the extra putty pack provided. If you're on the fence just go ahead and do it. I highly recommend this company to everyone!

Sentinel Mouthguards is the best internet purchase I've ever made! I am not comfortable with the whole dental process so to be able to do this from home so easily is incredible to me. The staff took time to answer my many questions and gave me plenty of tips & tricks to take a good dental impression. I have a friend that's a dentist and I showed her the night guard I received from Sentinel. She agreed it's a great product and even looks better than the ones her office provides! A+ service!

These guards are the best fitting. Exceeded my expectations. They are thin and comfortable but still offer the protection my tongue needs. No more pain and constant soreness.

New customer here! Lovely website, fantastic & friendly staff. My experience is that this small company offers a great teeth whitening solution at a price that was way lower than my dental office. I was dreading taking my own teeth impressions but this was a great, pain free experience! My teeth are so much whiter than they were and I didn't get any tooth sensitivity. Happy camper!

Sentinel Mouthguards is exceptional! Super accommodating, friendly professional customer service. I showed my retainers to my dentist and even he was impressed!

Smooth running machine! I'd give Sentinel Mouthguards 10 stars if possible. My experience has been nothing less than fantastic. The staff is very friendly and helpful. They replied to my emails promptly and took the time to answer my questions thoroughly. I sent off my dental impression and received my custom mouth guard within a week. The fit is so comfortable. They have FAR exceeded my expectations. Well ran team!
