Minimalist Sonic Toothbrush, Reinvented from the Bristles Up

Grin Teeth ET 3 series aren’t just minimal on the outside — they’re thoughtfully engineered Minimalist Sonic Toothbrushes, refined from the micro level.

100% End-Rounded Bristles offer ultra-soft, gum-safe contact, reducing microtrauma and irritation over time — perfect for sensitive mouths and daily use.
3D Multi-Level Bristle Design mirrors the contours of your teeth and gumline, allowing the brush to reach deep between teeth and into tricky corners effortlessly.
Built-In Color-Fading Indicator removes the guesswork — when 1/3 of the blue tips turn white, it’s time to refresh. It’s maintenance, simplified.

Every element of the brush head is designed with purpose: to do more with less.
No harsh scrubbing. No unnecessary bulk. Just smart, hygienic, minimalist care — from the first glide to the last bristle.

Make brushing intuitive. Make it beautiful. Upgrade to Grin Teeth ET 3 today.

Deep Cleaning That Reaches Where Others Miss

Grin Teeth ET 3 uses sonic vibration and soft tapered bristles to sweep away plaque, debris, and bacteria from deep between teeth and along the gumline.

Targeted Interdental Cleaning: The brush penetrates hard-to-reach areas, removing buildup that manual brushes often leave behind.
Gumline Protection: The ultra-fine bristles gently massage gums while clearing away bacteria, helping reduce inflammation and prevent bleeding.
Fluid Dynamics at Work: Sonic energy activates microbubbles and water flow, creating a vortex that flushes out hidden impurities.

Your mouth doesn’t just feel cleaner — it is cleaner, down to the smallest detail.
