Results from first use

Designed by Dental Professionals

Teeth whitening used to be expensive, time-consuming, and so potentially toxic that only licensed dentists could safely administer it. Yikes! We thought there had to be an easier, safer, gentler way...but there wasn't. Until we designed it. Smirk products help to whiten even the toughest stains without harsh chemicals. They're affordable, simple, and safe for anyone to use regularly in the comfort of their own home!

Brightening Smiles By the Millions!

Since 2014, Smirk products have helped whiten and brighten over 8 million teeth and counting! You'll find us in dental clinics around the world for that very reason. What makes our products special?

Remove Tough Stains

Smirk removes stains left by years of coffee, tea, smoking, and other indulgences.

Safe & Ultra-Gentle

All Smirk products are non-toxic and made without bleach or peroxide, making them safe to use and gentle on even sensitive teeth.

Get That Super-Clean Feeling

Love that “just visited the hygenist feeling” feeling? Smirk Powder also leaves teeth feeling post-dentist, teeth-lickingly good clean!

Safe for Regular Use

Keep teeth shining for the long haul with Smirk. Our products are safe for regular, long-term use.

I used this for the first time today and have a mix of real teeth and crowns. I could not believe the results just from the first clean. My teeth look a lot whiter and am looking forward to the next clean already. Fast delivery and great service. I will definitely be re-ordering, thank you Smirk.
