Customer ratings & reviews

Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

The fit is wonderful. I was so impressed by the comfort of this night guard. It conforms to my mouth and after several months of wear, it still fits perfectly snug.

Came on time as promised. Love it!!

Very fast shipping and excellent customer service. Would recommend.

THE 1mm THICKNESS IS PERFECT FOR DAY USE!! Chose this guard because I needed a thin appliance to wear during the day. Asked for the guard to be made like my old dental retainer. I sent a picture in for reference via email and received a very nice, very thin retainer-like daytime guard. It is perfect. No one even knows I'm wearing it. I do take it out while I'm eating. My jaw pain from clenching has drastically reduced. Think I may order a thicker night guard for nighttime clenching next but this one has definitely helped my symptoms. Thank you!

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.
