A great option for teeth grinding! I bought the boil & bite kind for years and they fit terribly. I was nervous about taking my dental impression. That was the big hesitation because I have a bad gag reflex. Talked to the lady on the phone and she walked me through the process. The fit is a world of difference and I couldn't be happier. If you're thinking about it, just do it. Well worth it.

Fits perfect! Thank you!!

Just wanted to say how IMPRESSED I am with the lower 2mm nightguard received. Over the years the price of night guards at the dentist office have been $400-$500 and my most recent quote was $798! The finished results at these facilities seemed less custom (even though an impression was taken). In addition, the appliances would require dremel-type grinding by the dentist on the actual appliance so that it would fit better in my mouth - I never expected that a nightguard from a mail-order could FIT LIKE A GLOVE, require no adjustments and feel so comfortable. I can even talk better with it in when compared to prior guards on my lower teeth. I do notice that after a week of use I have acquired a few minor rough spots on the guard from my obvious night grinding, so I hope that I have enough thickness, but that is not a complaint in the least. just a hope that I have the thickness is enough for me. Seems like there is always an option to go up in thickness if ever needed. A big THANK YOU for being an affordable and reliable resource in a time when dental and healthcare costs are soaring - I APPRECIATE YOU!

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.
