Customer ratings & reviews

I was referred by a friend who praised Sentinel's mouth guards and customer service. I live in Wisconsin and was worried about the mail service being dependable and timely. To my amazement, the entire process was smooth and fast. I am very impressed with the exceptional quality of my night guard and the timeliness of the transaction. I can't express how grateful I am for this service. Incredible!

My retainers have arrived. They're awesome. Much nicer than the very expensive ones I got from my dentist. Thank you!

Fast service, high quality and the fit is fantastic!

IMPRESSED! I've tried the cheapo guards from the drugstore and the dentist made version. I have to say this is the best night guard I've ever had. This is a fast and efficient way to get a professionally made night guard. Sentinel has a strong commitment to customer satisfaction. This is a great value.

10/10 recommend! Custom fit to my teeth and the process was straightforward/fast.

Perfect for flag football! I ordered this for my daughter who plays high school football. Got it in green which is her school color. She loves it! She says she can communicate with her team. It looks good on her. She's happy and so am I! HIGHLY RECOMMEND!

Just received my new retainers in the mail and they're perfect! Exceptional job in craftsmanship from a company that cares. The impressions were easy to do and included instructions + a helpful video of a woman taking her dental impression from start to finish.A+++++ HIGHLY RECOMMEND!!

EXACTLY WHAT I WAS LOOKING FOR The price is very reasonable. This is the exact same nice night guard I got from the dentist for a fraction of the cost. I highly recommend!!

Fits perfect and my teeth grinding has stopped! I was beginning to get hairline fractures in my teeth from grinding at night. Found Sentinel Mouthguards online and I paid a fraction of what my dentist wanted to charge me.The support team is proactive and responded to my questions fast. Got my night guard and it's comfy and fits my teeth perfectly. You will not be disappointed!

Impressive quality, fast delivery Having purchased from other manufacturers of night guards before, I can say that Sentinel Mouthguards creates high quality products and offers consistent, exceptional customer service. Plus, I received my night guard quickly after I sent off my impression! I'm 100% happy and will be recommending to all my friends and family
