Customer ratings & reviews

I can't say enough good things about this product and the companies customer service. The secret to getting a good fit is to read the instructions carefully and make sure that you submerge all of your teeth including the gum area evenly and do not remove until your 3 minutes is up! I had to learn this the hard way but the company sent me new impression kits at no cost! Second attempt worked! Very responsive and easy to work with. The guards felt a little tight on my teeth at first but became comfortable after a few nights.

This is the first product I have found that actually works! I am a chronic tongue biter and have damaged the edges of my tongue. My tongue bleeds and is very painful. The soft dental guards are comfortable. It took me about a week to get used to sleeping with them comfortably. They are thin and my tongue has quickly healed. I cannot express my gratitude and the relief I feel. Thank you!

Love everything about my new Sentinel night guard!

I drink a ton of coffee and I just live my teeth whitening trays. Keeps my teeth from yellowing because I don't want to give up my coffee!

Excellent fit and highly recommended! The process is easy. I was a bit wary about ordering online but after reading the reviews on this company I decided to give it a try. Great all around! Thanks Sentinel Team!

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.

Fast, friendly service at an unbeatable price!

Bought this for my daughter. She said on a scale of 1 to 10 it is a 10 in comfort! She's been a longtime teeth grinder. The dentist said she would grow out of it as a child but here she is at 18 still doing it. We have tried the walmart guards and they never were comfortable enough for her to wear during sleep. Truly the best! We looked around and decided on Sentinel. Glad we did. Thank you!

My daughter has seizures and has had terrible pain from biting her tongue during her episodes. I searched for a long time to find something that would help her. The dental impression process was very easy to do. I helped her with her impressions and we received two very well made soft night guards. She wears them nightly just in case she has a seizure. So far so good. They're very thin and soft yet firm and I feel better that she has something protecting her from damaging her tongue any more.
