Customer ratings & reviews

Came on time as promised. Love it!!

Very fast shipping and excellent customer service. Would recommend.

The mold arrived fast but the guard takes a while to make and ship, be patient. It is worth the wait.

The mold kit arrived by 21 September & after mailing in your mold, it takes an additional week to receive your customized mold...which fits perfectly as advertised...

Placed my order on June 12th and the process is already complete! Customized night guard arrived in a retainer case & enclosed in a large bubble mailer. Craftsmanship is high quality. Fit is superb. I look forward to getting many years of use. Thank you team!

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!!

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!!

Sentinel! Thanks for keeping my teeth protected! I've been a customer now for 4 years and am a bad grinder. You stood by your warranty when I ground through my first night guard after 16 months. Just ordered another. Can't thank you guys enough for making custom night guards affordable.

I love this mouth guard. It is THE most comfortable one I've ever had!! Thank you!
