Customer ratings & reviews

Thoroughly surprised! I'm very pleased with my purchase. Great quality at a great price!

I have been wearing night guards for over 10 years. All those years paying $600 every time I wore one out and I never thought to check online. The quality and fit are just as good as my dentist. I'll never pay those kind of prices again. You have my business for life! <3 Rachel

Took the quiz to find out which night guard I should get and it said a hard guard. I was skeptical that the hard one wouldn't feel comfortable. First few nights took some getting used to but now I love it. The whole process was smooth, shipping was fast and easy and the night guard fits like a glove. Here's a tip: When you take your dental impression, make sure your teeth are centered in the tray and sink your teeth into the putty all the way while holding still. Don't move around. After 2 minutes or so, the putty should be hard and you can remove the tray. Make sure your impression looks correct before sending it in or they'll have to send you a new kit. I sent in a picture of my impression and they were quick to respond. I hope this review helps someone!

This is the best! I've tried many guards over many years of suffering from TMJ, and none worked or were comfortable to wear. This guard is extremely comfortable and really does help with relieving my jaw pain and protecting the teeth from grinding. Customer service team is very nice and fast. Excellent all around experience!

HIGH QUALITY AND HIGHEST LEVEL OF SERVICE ***** I 100% recommend this dental night guard delivery service. They remove all of the excess plastic for a slim fit. Not at all bulky in the mouth and crafted with care. Thank you Sentinel team!

My teeth and jaw were so bad off before I started using the Sentinel guard. I have a 2mm upper. It's a lifesaver! I can't sleep without it now! 5 stars and I'd give 10 if I could!

This is my 2nd Sentinel night guard and I will never buy from my dentist again. He charged me $550 every time I went in for a new one and they never lasted more than a year. I will be a long time customer and will continue to recommend Sentinel Mouthguards.

Didn't work out for me. I found out I needed extensive dental work after I ordered. Contacted the company and told them my situation. They issued my refund immediately. Suzanne is the sweetest! Thank you for making this easy for me and once I have all of my work completed I will definitely be back!

AFFORDABLE AND PRACTICAL! Nothing fancy, but that was exactly what I was looking for! I hated how terrible my cheap, store bought guard fit. This does the trick and worth the wait!

This worked PERFECTLY. I clench my jaw during the day and at night and have sensitive teeth because of it. I had a $400 mouth guard from my dentist but it was so uncomfortable I couldn't wear it. I chose the 2mm thickness after talking to customer service. It's thin but the quality is still high. I will definitely never be buying guards from my dentist again. This is a wonderful product!
