Customer ratings & reviews

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.

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

THIS IS IT!! I tried 2 other mouth guard companies before I settled on Sentinel and I won't be going anywhere else! From the customer service to the impression teeth process to the receiving my night guard, it was quick and painless. My night guard fits like a glove. I sleep with it every night and my jaw feels 100x better. If you want experience and professionalism, this is it.

I originally ordered the soft guard but my teeth grinding is a little more intense than I thought it was. I saw wear marks on the soft one within the first month of use. Contacted Sentinel and they suggested a more durable type. After some back and forth, I decided to give the hard guard a try. Really impressed with the quality and fit. It's thin but offers the protection that I needed. I can sleep with it in easily and I'm even getting to where I prefer to sleep with it. Never thought I'd say that! If you're considering ordering a custom night guard online vs the dentist, this is the company. Fantastic work all around! A+++++++

I wish I'd bought a Sentinel guard years ago. I had been using the boil n bites and they were always too big for my mouth. I felt like I chewed on those more! This type is hard so I can't chew on it. It's so slim and comfortable. A world of difference for me. I will update this review to speak on the longevity but for now, a huge thank you!

I have been wearing night guards for 30 years and this is by far the most comfortable one I've ever worn. The fitting kit was easy enough to manage. Turnaround was quick! Amazing! Thank you so much.

Get one!! You will be impressed with this company! For the past few years, I've been experiencing jaw clenching during my sleep. Although it may have started due to stress, even during periods where I felt calm, it continued to persist. The issue was further aggravated by a cheap night guard that I purchased for less than $20. I did some online research and decided to give Sentinel a try. Their customer service is excellent. Very helpful with the molding process and my night guard fits great! I'm entirely pleased and would recommend this service to anyone. A+

Fantastic experience with Sentinel Mouthguards! From customer service to timeliness of the deliveries and receiving my night guard, everything was impressively smooth. I will be recommending this service to anyone who grinds their teeth. Thank you Sentinel!

Great customer service is why I continue to return every 2 years for new guards that I have chewed through.
