Perfect oral care is rare.

Most people don’t brush four times a day, floss twice a day, or keep up with every device.

That’s 90% of the world—or as we call it: the rest of us.

We created Great Gums for people who want real oral-health results without needing a perfect routine.

Why We’re Different

We didn’t just build another electric toothbrush.

Our patented bioelectric microcurrent technology is designed to boost circulation, support gum healing, and elevate everyday brushing.

This is the future of gum-first oral care. It’s brushing and oral-health therapy at the same time.

Oral-Health Leaders Behind the Mission

Our patented bioelectric technology was designed by our co-founder Dr. Young Wook Kim and a team of elite Korean engineers—experts in microcurrent and electromagnetic wave science. Alongside them are industry veterans—former Sonicare leaders, Colgate researchers, Ivy League clinicians, and digital-health innovators—led by CEO Mark Goldstein. Together, they’re reshaping oral health with real science and real results.

The Industry Is Stuck. We’re Moving It Forward.

Toothbrushes haven't meaningfully changed in 30+ years, and they've ignored the true foundation of oral health: your gums.

More than 50% of first-time users feel the dentist-clean difference from Great Gums’ bioelectric technology alone.

With protectable IP, clinical testing at Columbia University, and 700,000+ customers, we’re building momentum—and preparing for the next evolution with Sonic Gums’ release.

Sonic Gums = The Next Evolution in Oral Care

Sonic Gums is the newest innovation in oral care, combining bioelectric microcurrents that boost circulation and reduce inflammation with advanced sonic technology for superior plaque removal. Its hybrid design delivers a deep, effective clean without harsh high-frequency vibration, and the system’s underlying bioelectric technology has been clinically tested at Columbia University.

We Built What the Giants Didn’t

Philips. P&G. Colgate.

They built toothbrushes.

We built an oral-health system: a brush that not only cleans teeth, but actively heals and strengthens gums.

We have proprietary IP, a technology category no one else has, and a mission big enough to redefine oral health globally.

Because the future of oral care isn’t just brushing better.

It’s protecting the foundation your smile depends on—your gums.

2025 is the year we shake up the industry.

Our mission is simple: Convert Sonicare, Oral-B, and manual toothbrush users to bioelectric brushing.
We’re focused on selling two brushes—because once people feel the difference, they want another. One for home. One for travel. One for a partner. However they switch, we’re making it easy.
The world is moving forward—so should your toothbrush.
