Customer ratings & reviews

This is the best mouth guard for heavy teeth grinders. I have been through many mouth guards from store bought to dentist made and Sentinel Mouthguards makes the best ones. Impression process was easy for me but that may be because I've had several taken over the years and knew what to look for. They do send an extra putty for a 2nd attempt and they are quick to reply via email if you send a photo to doublecheck the quality of your dental impression. Overall, they're a great company with an even better product. If you're on the fence, I highly recommend!

I just wanted you to know I am so grateful to you guys, thank you so much for redoing my night guard in the thicker material. It absolutely did the trick and I am sleeping without jaw pain. I’m waking up without headaches and I just can’t thank you enough. But I wanted to thank you for going the extra mile and fixing that for me, and sending it so promptly. Y’all have a blessed day and drive safely!

Works perfect!! I have had night guard from other online companies and the fit was never right. Received my Sentinel guard and have been using it for several nights. I love this one. Best night guard I've ever owned! Fit is perfect, quality is high and the process was FAST! A++++

Love this company!! I have ordered 2 guards from Sentinel plus a teeth whitening kit. Everything I've received has fit perfectly, it's high quality and the service is fast and friendly. Sentinel has my business for years to come. Thank you for doing things right!

The absolute best night guard ever! So glad I found this here. My dentist was asking for $600. Fit is true to my mouth and my jaw pain is gone!

Half the cost then my dentist is selling for the exact same product and same results.

The communication was excellent, and the turnaround time was very fast. I would highly recommend this company for anyone looking for a reliable night guard provider.

The process was easy and straightforward, and customer service was patient and helpful in answering any questions. I received my mouthguard and the fit is flawless. Excellent experience!

The customer service of this company is wonderful. They're a small, family owned business and I love that everything is made right here in the USA! I have a gluten allergy and learned that my dentist was using a Chinese lab to make his night guards and couldn't verify the materials in it! I was able to order a gluten free mouth guard from Sentinel that fits perfectly and I couldn't be happier! Excellent product and service!!

I love my first night guard. Had some dental work done so ordering my second! I suffer from TMJ and this guard I wear for my lower teeth. It helps greatly with my jaw pain. No more popping and clicking since I started using it. The Sentinel team is fast, courteous and the product does the job at a price way lower than my dentist. Amazing!
