Customer ratings & reviews

Ive had my mouthguard for about a year and a half now. Just had to use my warranty to get it replaced. Felt inclined to leave a review about my experience. Sentinel Mouthguard Co. stands by their replacement warranty. No questions asked, I simply attached a picture of my nightguard showing existing wear to an email to the company. Within 10 days I had my replacement. I don't know of any dental office that has a warranty like this. Exceptional customer service & product. Thank you Sentinel. Sincerely, Gabriel M.

Sentinel exceeded my expectations in every facet. Fast and helpful service! The mouth guard fits and works perfectly. I ordered the thickest one and have had it over 6 months. My family and I will continue to use this service for all of our mouth guard needs. Just ordered my son the sports guard for football!

Perfect fit and above all, Sentinel's customer service is excellent. I had an issue with shipping and it was immediately addressed.

Simple and easy! I got the teeth kit quickly, took my lower impression using the instructions. Mailed it back to the company and received my custom made mouth guard within a few days. Fit perfect right away and I use it nightly A+ company

After losing my custom night guard from my dentist I decided to give this a shot. I was hesitant at first but decided to go for it. Glad I did!! This night guard fits better than the one my dentist made me. Not only that, but it was 1/5 of the cost! I'm a very satisfied customer and will be ordering these from now on.

Best fitting and great customer service!!

I AM VERY PLEASED The comfort of this night guard exceeded my expectations. I use this product from grinding in my sleep and it works well. Stays in place all night. I can even talk with it in easily. Came with a quality storage case and a warranty! Can't beat it!

Super comfortable and easy to wear. I would recommend.

Perfect fit! Thanks! -E.D

What a difference it has made in my jaw! I was waking up with horrible jaw pain and headaches. Wearing this guard has been an absolute life saver!! Fast shipping and probably the best night guard ever! I'm team green! Go Sentinel!
