Protect Your Smile, Discreetly

All-Day Comfort, Invisible Protection

Unlike bulky night guards, the No-Show Day Guard is custom-molded to fit snugly behind your back teeth. It's so thin and comfortable, you'll forget you're wearing it – while it silently shields your teeth from grinding and clenching damage.

"I bought a dental guard from Sentinel and was so pleased with the service and fit of my sleep guard that I decided to try out the teeth whitening. I've always had little to no success with other whitening products so I was skeptical. I would recommend this whitening regimen to anyone. Worked absolute wonders on my coffee and tea stained teeth Happy camper!!"

Stop Headaches & Jaw Pain

Break the Cycle of Tension

Daytime teeth grinding can lead to headaches, jaw pain, and TMJ issues. The No-Show Day Guard creates a barrier between your teeth, preventing them from grinding together. This reduces tension in your jaw muscles, alleviating pain and preventing future headaches.

"My dentist sells this SAME EXACT KIT for $400. Same gel, trays everything. So glad I found it on here. My teeth get so white so quickly with this stuff. Thank you for making this affordable!"

Maintain Your Confidence

Smile Brightly, Worry-Free

Don't let teeth grinding ruin your smile. The No-Show Day Guard protects your teeth from chipping, cracking, and excessive wear. This lets you smile confidently, knowing your teeth are safe from the harmful effects of bruxism.

"Wonderful results! My dentist doesn't offer deals like this! Lucky to have found you Sentinel!"
