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.

I clench my teeth a lot at work, and I've tried many night guards of all types. They never form well and they're bulky. This night guard is nice. I can close my mouth, talk, drink water, etc. It's the best of its kind I've used. I would highly recommend it.

I couldn't find a night guard lab locally, so I purchased this one online & I'm so glad I did. I use this product daily and nightly. The material is soft, clear and unnoticeable. I went with the lower teeth guard. Impression process was easy. I made a nice mold of my teeth. The guard itself is sleek, slim and not too tight. Once I use this one up, I'll definitely purchase this night guard again.
