Customer ratings & reviews

READ THE INSTRUCTIONS! I had high hopes of getting my teeth mold right the first time but I let the putty get too hard. The second time I hit the front of the tray with my teeth and distorted it. They sent me another kit with two more tries in it. This time, I read the instructions and watched the video and nailed it!! My night guard fits great and it is high quality. I have sent many of my family and friends to get their custom mouth guards. A++++

Completely relieved my sore jaw. I wear this during the day because I clench my teeth while sitting at my computer. It's comfortable and I can talk with it in.

Insurance wouldn't cover my nightguard through my dentist. Read an article online and found Sentinel through the article. So happy I did! I paid a fraction of what my dentist wanted to charge me. Happy customer!

I've found the company I was looking for! I went through my dentist at first and it was a horrible experience. I have had bruxism for years due to stress and the mouthguard he made me cut my gums. He tried to "fix" it but it was still awful. The difference between this mouthguard and the one I received from him is incredible. The material quality, the fit, everything is sooo much better. Thank you for offering this to people and doing a BETTER JOB THAN THE DENTIST!

Customer service is out of this world good! I decided to purchase this guard after my dog chewed my old one. I had several questions about the process. Customer service was excellent! My kit arrived fast and the molding process was simple. The mouthguard I received is very well made and fits extremely well. All in all, my experience was a very positive one and I will recommend to family and friends.

Doing it right! Excellent customer service and a great product. I Highly recommended to anyone wanting to save $600 at the dentist or tired of spending $30-$50 every couple months on OTC sleep guards.

A Must-Buy! I tried other online companies and the fit was never right. This company gives you extra putty in the impression package to make sure the mold is correct. They give clear instructions for taking your impression. I took mine correctly on the second try. First try I hit my front teeth against the tray. Mailed it in and received my night guard about a week later. I sleep with it every night. My jaw pain and headaches are GONE! I'll be buying again in the future when this one wears out.

Very good, dependable service! Reliable, fast and helpful with a great product! Would recommend!

Great night guard! I used to buy the bulky boil & bite guards because I didn't want to pay the price but I always ground through them and ended up spending more money than if I would have just got a custom one! Fantastic fit and high quality. Couldn't be happier with my purchase!

Finally an affordable option! This is now my favorite company! Process was easy and mouth guard fits like a glove. I highly recommend.
