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.
The brush that
heals
while
you clean
Our patented brush uses bioelectric microcurrents to boost circulation, reduce inflammation, and heal gums—while you brush.
Built by top engineers and dental experts, including researchers from Colgate, and tested in clinical trials at Columbia University.
We’re changing oral care forever.
From Korea to California:
Redefining oral health
We started in Korea with one simple belief: oral health is foundational to overall health. Now, from our new San Francisco headquarters, we’re bringing that mission to millions across the U.S.
Patented bioelectric technology
700,000+ customers worldwide
Clinical testing at Columbia University
The

behind
the revolution
CEO & Founder: Mark Goldstein
Mark knocked most of his front teeth out in a water ski accident twenty years ago and since then has gotten to know his dentist a bit too well and this was a decade or so after his parents invested in 5+ years of braces!
Serial entrepreneur and healthcare innovator, Mark co-founded Great Gums to bring this revolutionary technology to the global market. His experience spans fintech, SaaS, e-commerce, and health sectors.
Co-Founder: Young Wook-Kim
Meet Young, the creator of Great Gums Technology and Founder & CEO of Proxi Healthcare Inc. A young biotech startup with headquarters in Seoul, South Korea.
Young developed groundbreaking micro-current at the University of Maryland in electromagnetic wave technology (and received multiple patents) to remove plaque, inspired by his personal health journey and professional background in biotechnology and engineering.
We've been reimagining oral care through science, technology, and innovation—guided by top dental minds from Colgate, Sonicare, and biomedical engineering who share their mission.
Because we think 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
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.
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.
We Built What the Giants Didn’t
Philips. P&G. Colgate.
They built toothbrushes.
We’re building an oral-health system: a brush that not only cleans teeth, but actively heals and strengthens gums combined with a proprietary toothpaste formulation.
We have proprietary IP, a technology 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.
The Science and People Powering Our Mission
Our patented bioelectric technology was created by Dr. Young Wook Kim and a team of leading Korean engineers who specialize in microcurrent and electromagnetic wave science. Alongside them stand former Sonicare and Colgate leaders, Columbia University clinicians, and digital-health innovators—united under CEO Mark Goldstein.
These are the people driving real change in oral health.
