Customer ratings & reviews

I would agree with everyone below. Sentinel's customer service is #1. I received several emails throughout the process keeping me informed. I was thinking to myself another automated email system but they were all informative, useful emails with my tracking information etc. They are quick to respond through email as well and I received my night guard within about 3 weeks from the order date. *****

Messed up my impression the first time. Sent a picture in and they told me that it wouldn't make for a good night guard so I used the extra putty that was in the kit to try again. About 1 1/2 weeks later I received my guard. I'm glad they care enough to supply an extra putty pack for a retry and provide such friendly customer service. Will be back because I don't think this teeth grinding habit is going anywhere!

Same as dentist. Thank you sentinel team!!

This is the only brand I trust. I've been a Sentinel customer for 10 years. Their customer service is great. They're consistent and I love their night guards. I have a no-show day guard that I wear during the day and the extreme durability guard at night. Nothing less than a positive experience for me. 5 stars!

Love this service! I have been ordering mouthguards from Sentinel since 2013 and have never looked back! My dental office was charging me $700 for these hard guards. I'm a bad grinder and go through them quicker than most. Sentinel Mouthguards has great customer service and an even better product. Happy to be a faithful customer! I have and will continue to recommend this to friends & family. Sabrina C.

This is a quality product like you would get from a dentist. Thanks.

Glad I gave them a try! It didn't work out for me at first because right after I placed my order, my tooth broke and I needed a new crown. I called them and they told me I could hang on to the teeth impression kit until my dental work was completed. Well, it took me 1 year to save up for the crown. I called and they still honored my order. That's what I call great customer care! I received my new night guard and it fits beautifully. Happy customer!

Never had a bloody mouth again! Instant relief. The sores on the insides of my cheeks healed completely within days. Awesome product!

UPDATE: My dang dog chewed them to bits less than a month after I received them, called company and they did hold up their claim to keep the impressions on file. I'm thankful for that, because I can at least reorder and not have to take dental impressions again.Received a 20% off discount too. Two thumbs up for it. Customer service is good.

Easier than I thought! I was nervous about using this but the putty process was easy and they include a free putty pack in case you need to redo it (which I did need a 2nd try). I even called the customer service line and had them stay on the phone with me while I took the impression. They were terrific and very helpful. My guard fits beautifully. A+ service!! Will be back.
