Customer ratings & reviews

Excellent Customer Service!!

This is my second purchase from this company. I needed some adjustments to my Guard and it was so easy and such a pleasure to do. I will only recommend Sentinel to anyone, and only buy from them. Fantastic Company

Great product great price!

This is my third or fourth mouthguard over the last 6 or 7 years. The only issue I’ve had is a little bit of soreness when I first get the mouth guard, until I get used to it.

Fantastic price, more minimalist than bulky

I’ve used custom night guards for years. I’m used to them being a bit more bulky and was surprised when this one looked so minimalist. It took me a little while to get used to it but it has been great! I like that it’s not as bulky and does the job just fine.

Grind on!

Great fit after second impression! World crisis justifies tooth grinding. Sentinel has me covered

Fits great!

Custom fit; prevents night grinding

Dentist Quality w/o the High Cost

Easy, affordable and effective. So glad I decided to go with Sentinel instead of going through my dentist. Saved $450!

Love my new mouth guard!

Great fit and Customer Support

Sentinel provides a great product and they are polite and prompt in answering any questions. My dentist was impressed with the materials and fit of my nightguard.

IMPRESSED! I've tried the cheapo guards from the drugstore and the dentist made version. I have to say this is the best night guard I've ever had. This is a fast and efficient way to get a professionally made night guard. Sentinel has a strong commitment to customer satisfaction. This is a great value.

Fits perfect and my teeth grinding has stopped! I was beginning to get hairline fractures in my teeth from grinding at night. Found Sentinel Mouthguards online and I paid a fraction of what my dentist wanted to charge me.The support team is proactive and responded to my questions fast. Got my night guard and it's comfy and fits my teeth perfectly. You will not be disappointed!
