San Francisco, CA — May 13, 2026 — Great Gums today announced that the results of its clinical trial evaluating its bioelectric toothbrush have been accepted for publication.
"These findings support bioelectric technology as a clinically validated method for improving gum and oral health outcomes and for managing plaque. For dental professionals, the results now confirm that bioelectric toothbrushes serve as a valuable addition to at-home care, particularly for patients experiencing persistent inflammation or bleeding," said digital health pioneer Mark H. Goldstein, Great Gums CEO and Founder of the Digital Health Hub Foundation.
Melissa Turner, the nation’s top dental influencer and a dental hygienist, added: "Great Gums is my go-to brush, and I've tried them all. I was a skeptic, but I use it every day and it's no BS."
The randomized, controlled clinical trial was designed with contributions from dental researchers affiliated with Columbia University, in alignment with American Dental Association (ADA) clinical and labeling guidelines. The study was conducted over a four-week period at Ulsan University Hospital in South Korea, with Institutional Review Board (IRB) approval. Ninety-nine participants with mild-to-moderate gingivitis were assigned to one of three groups using a bioelectric, manual, or sonic toothbrush. To ensure objectivity, the evaluating dentist was blinded to group assignments.
After four weeks, participants using the bioelectric toothbrush experienced:
- 50.8% reduction in gum inflammation
- 64.2% reduction in gum bleeding
- 17.9% reduction in plaque
All improvements were measured relative to participants' starting condition, with the bioelectric toothbrush outperforming both manual and sonic comparators across all clinical endpoints.
Gum disease remains highly prevalent, even among individuals who brush regularly, in part due to the limitations of mechanical plaque removal. Great Gums' approach utilizes low-level bioelectric currents designed to disrupt bacterial biofilm and improve cleaning effectiveness, particularly in areas less accessible to bristles alone.
