Science First. Proof Delivered.
No one believed our technology worked—so we proved it.
In late 2024, we launched Great Gums backed by six+ clinical trials overseen by our co-founder and inventor, Young Kim, in South Korea. The results were compelling, but dentists wanted U.S.-based proof under recognized clinical oversight. So we commissioned a rigorous clinical trial and put our brush to the test.
A New Standard of Validation
We partnered with top clinical experts, including a former Colgate clinical researcher, with oversight aligned to ADA standards and under the auspices of a Columbia University School of Dental Medicine professor. At a leading U.S. research institution, we completed a controlled human clinical trial in summer 2025. The results were decisive.
We're finalizing our ADA acceptance and getting our study published in a leading research paper shortly. Preliminary details are discussed in the video below by Luiz Andre Pimenta, DDS, MS, PhD, MBA, professor of at the Columbia University College of Dental Medicine.
In just 4 weeks, study participants experienced better gum health than manual and sonic brushing alone, less plaque than manual brushing, and no adverse events
Our innovative hybrid of sonic cleaning + bioelectric microcurrents disrupts plaque’s “hold” so it’s easier to remove, and supports cleaning where bristles can’t fully reach.
What’s Next
We’re proud to extend this clinically proven technology across our full line of brushes — and we’re excited to introduce our own toothpaste formulation designed to work synergistically with our brushing system.
This is more than a toothbrush.
It’s a new standard in preventive oral care.
Happy Brushing,

Silvana Barros, DDS is continuing our research in the United States alongside our founder, Dr. Young Wook Kim. In vitro studies are being conducted at The Columbia University College of Dental Medicine to further research various aspects of the Great Gums brush performance. The findings from these studies will be published and will also guide a subsequent clinical trial.
