WE’RE NOT JUST SURFACE LEVEL.
We protect your foundation—
your gums.
Most people lose teeth not from cavities, but from silent gum disease — the #1 cause of tooth loss. It’s painless, invisible, and affects 80% of adults.
We don’t just clean teeth — we protect what holds them.

heals

you clean
Our patented brush uses bioelectric microcurrent to boost circulation, reduce inflammation, and heal gums—while you brush.
