Customer ratings & reviews

This was a great purchase. My teeth had finally gotten to the point of no return and I had to do something. This fits perfectly. Easy instruction and feels Great!!!!!

The quality is unmistakable as is the comfort. This guard is the perfect fit and just like the one I ordered from my dentist years ago. This is the real deal. I highly recommend -JL

This night guard lasted me over 6 years and I just ordered my 2nd one. High quality and well worth it. Beats the heck out of going to the dentist.

Fabulous product! Should have done this a long time ago. My jaw pain has gotten so much better. After the first night I noticed a huge difference. During the day, I don't experience the popping and clicking like I used to. I recommend this.

A good way to treat canker sores on your tongue! It really works!

Comfortable, easy to fit and sturdy! I've worn through 2 night guards from my dentist. If you grind your teeth while sleeping this is the product for you.

Best night guard ever!! Hands down. Better than my dentist. The company is professional, prompt and courteous. Most of all, they make an excellent product. I have recommended to multiple family members and friends. Keep up the good work Sentinel!

Fast and affordable. Great delivery service for custom night guards. My dog loves these lol so it's a good thing I have found an alternative to my expensive dentist! Thank you!

Thumbs up!! Went through a different company initially. It didn't pan out. Won't go into the story with that but this was a much better experience. The night guard is slim despite it being the thickest one. It covers about halfway up my teeth. Not too tight. But most importantly I'm not grinding my teeth anymore! Thank you.

Teeth impression kits arrived quickly. They supply an extra putty pack for a re-attempt. I ordered a lower guard so I did take 2 impressions of the lower teeth and sent in a picture to the email. They replied almost immediately with a yes to the impression picture. Received the guard in the mail within about 1 1/2 weeks after sending in the impression. Guard is thick and durable but that's good because I'm a heavy teeth grinder. It took a few nights of wearing it to get used to it as this is my first experience with a custom made night guard. I have worn the cheap plastic ones from the store and they're not comparable to the quality of this one. Very satisfied with the experience. A++++
