Customer ratings & reviews

The mold arrived fast but the guard takes a while to make and ship, be patient. It is worth the wait.

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.

Bill Bass here- Just wanted to check in and tell you all that your company is exceptional and the service you are offering is outstanding. I've been a loyal customer for 3 years and don't plan on going anywhere. Gracias to you all.

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.

The mold kit arrived by 21 September & after mailing in your mold, it takes an additional week to receive your customized mold...which fits perfectly as advertised...

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.

I was looking at paying $600 for replacement dental retainers after my dog chewed them up. I am grateful to have found your service! The impression process was easy. I thought I might gag on the impression substance because at the dentist they used a messy, goopy mixture that fell to the back of my throat but luckily the impression substance sent to me was not like that at all. The girl on the phone said it is similar to playdoh and that is exactly right. Even smelled like mint! I just wanted to let you all know that I appreciate this service being available online and if my dog ever gets a hold of my new retainers again I will be back!

Best fitting and great customer service!!
