Customer ratings & reviews

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.

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!

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

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

I received a very expensive night guard from my dentist and it was so bulky I couldn't close my mouth let alone sleep with it in! I called Sentinel customer service, spoke with a very nice lady and she suggested this guard type. I went with the "thicker" option and was assured that it would not be bulky. She was right! It's perfect for my mouth. It protects my teeth well and my jaw says THANK YOU! For the impression process, I received a kit in the mail quickly after ordering. It came with an extra set of putty and I didn end up needing it bc my first impression was too shallow in the back teeth. I sent a picture in and again the communication was fast. The reply email stated the reason why it wouldn't be acceptable and came with a reference picture of a great teeth impression plus additional tips. I retook my impression and it came out much better the second time around. The shipping of the night guard was quick. I received an email when it shipped and it didn't take the lab long to make it at all. The night guard is flexible and clear. It appears to be high quality material and has felt comfortable in my mouth right from the beginning. My experience has been great and I recommend this company without hesitation. A+++
