Customer ratings & reviews

Perfect fit! Great service!

I had trouble getting a good enough impression but customer service was patient with me. I also needed to wait to do this because of some dental work. So not only did they let me hold onto the impression kit for 6 months while I was getting that completed, I messed up my impression when I was finally ready and they sent me a new kit for free! This company has earned my business for years to come. The guard is a perfect fit and quality is high. I will say be careful when mixing the putty and watch your time. I went over the time (mixed too long) and the putty hardened like a rock the first time. Second attempt was successful. Also, they tell you to send a picture in so they can see if it's a good impression before mailing in. I would recommend doing this. They respond fast and it saves time.

FAST AND AFFORDABLE!! A+

Amazing! Highly recommend. I'm a hygienist and have been recommending these guards to my patients for years. I wear one myself and I love passing on the quality and savings to my patients. Will happily continue recommending them for years to come!

Found this company online. The staff was friendly and helpful. They answered my questions in a prompt manner. The finished product is of highest quality. I am happy with my purchase and will order again in future.

This is a great dental guard. Nice and comfortable. Big thanks! -Jim

Best night guard ever!!! After 30 years of grinding my teeth I've seen it all. I've tried every type. I've had allergic reactions to the dentist made ones and I've worn the cheapo's from the drugstore. With my experience, I feel I'm the right person to tell you that this guard is a steal! The quality is high, the service is great and it fits like a glove. If you're on the fence, this is a good buy. Highly recommend!

Fabulous service!

We use these in our family. My mother wears one, myself and my husband. We are a family of teeth grinders! We love these night guards and the great team at Sentinel!!!!! So bright and cheerful, they are always there to help us. These guards lasts a long time. Will absolutely order more in the future.

Outstanding product and service! Sentinel's customer service is unparalleled!The care and individual service I received is worth writing a review for. I greatly appreciate the excellent customer service and their willingness to go above and beyond.
