Customer ratings & reviews

I can't believe I have been paying $600 a pop all these years for the exact same nightguard as this one. After I lost my last one, I contacted my dentist who wanted to still charge me full price for a replacement. I was hesitant to order from Sentinel because how could it be the exact same thing for so much less? I'm so relieved I went ahead and made the purchase. You all have a customer for life. Thank you.

I ordered a dual laminate and a thin hard night guard (for daytime use). Got my two mouth guards and both fit great! You all have been a pleasure to work with. Thank you!!

Easy and inexpensive!! 5 STARS!

It just makes more sense! Yes there's some time involved in taking your own dental impression but the money saved just makes sense. Better quality, better service and I never had to leave my home. Goodbye dentist! Hello Sentinel!

I am 100% satisfied with not only my purchase but my experience with Sentinel Mouthguards. After losing my dentist made guard, I tried the store bought one and that was disappointing to say the least. I needed a custom one but couldn't afford to go back to the dentist. Sentinel makes it easy to get a high quality, custom guard for much less than the dentist! Great service, great product.

Just reordered after my last Sentinel night guard lasted me 4 years. I ordered a 3mm thick one this time and hope to get even more years out of this new one. You have a customer for life and I recommend you to all of my friends & family.

I hope you guys never go anywhere because I don't want to ever have to go back to paying the prices at my dentist. I just ordered teeth whitening but I have had past night guards from you guys for years. I'm just as impressed with the quality of the teeth whitening system as I always have been with my night guards. Have told my family and friends and will continue to spread the word!

Just received my dental guard and wanted to let you know it fits perfect! I was very nervous about using this system. Especially because in the past, the dentist has had to do some adjustments to my guard to get a great fit. This guard instantly snapped in to place. It's thin and perfect. Thank yoU!

After one year of use I noticed the dual lamination separating on my guard. Contacted Sentinel and they allowed me to simply upload a picture (proof of dual lamination separating) and sent me a replacement free of charge. Zero hassle. Wonderful customer service. Also, the night guard has helped me tremendously with my teeth grinding pain. I continue to recommend!!

What a delight to find a company that doesn't want to take every dollar you have. These guys are not solely about profit. They give a damn and it's obvious. Huge thank you to you all. Thank you for making this affordable to the people who don't have deep pockets. Love my nighttime guard. Will recommend this to everyone I know. *****
