Five Stars for Customer Service

Unfortunately, the hard night guard did not work out for me. The first time I received it, it was too tight. Emailed customer service and they sent another impression kit free of charge and sent me another guard. It was still too tight and made my teeth feel pressed together. I worked with customer service again and sent this one back so they could adjust it. It fit better when they returned it but was still giving me the sensation of pressing my front teeth together. I emailed customer service again and they are sending me a dual laminated guard now, since it will have a more forgiving fit. Sentinel really honors their guarantee and have been very kind to work with. They haven’t given me any push back in working to make sure I get a mouth guard that fits. I am really impressed with their customer service more than anything.

Night guard

The guard fit perfect. I highly recommend Sentinel Mouthguards.

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.
