Electric Flosser Proven to Remove Significantly More Plaque Than Traditional Floss

A new clinical study demonstrates that Flaus, an electric flosser, removes over seven times more plaque between teeth compared to traditional, ADA-approved string floss. This finding positions Flaus as the only clinically backed electric flosser currently available on the market.

Study Details and Findings

The study, titled “The Evaluation of Interdental Plaque Removal Efficacy of Flaus® Electric Flosser compared to Brushing Alone and String Floss,” was conducted by SLS Clinical Research Consulting at Salus Research in Fort Wayne, Indiana ¹. The research team included J. Milleman, K. Milleman, S. Santos, A. Yoder, T. Grahovac, K. Wills, and T. Eads.

Key findings from the study include:

• Flaus removed 7.74 times more plaque than the leading ADA-accepted string floss.
• Flaus removed 10.5 times more plaque than brushing alone.
• String floss, when used with a manual toothbrush, did not demonstrate significantly different plaque removal compared to brushing alone.
• Brushing with a manual toothbrush alone did not remove clinically significant levels of plaque.

Specifically, proximal surface reductions in plaque were as follows:

• Flaus + Manual Toothbrushing: 37.4%
• Traditional String Floss + Manual Toothbrushing: 4.3%
• Manual Toothbrushing Only: 3.3%

Addressing Compliance and Accessibility

Flaus was designed to address the widespread issue of inconsistent flossing habits. Approximately 60% of Americans don’t floss regularly, and 30% don’t floss at all ¹. The device’s 18,000 sonic vibrations per minute, ergonomic design, and 60-second routine have resulted in a 90% compliance rate among users.

Flaus aims to improve accessibility for individuals with physical limitations, such as those managing arthritis, stroke recovery, cerebral palsy, or limb differences. Features like a one-button design, ergonomic handle, and Braille packaging contribute to its usability.

Study Methodology

The clinical study involved several key components:

• Ethical board approval was obtained prior to commencement.
• Participants underwent three 48-hour “practice” periods to familiarize themselves with the flossing and brushing routines.
• Participants were included if they had at least 20 natural teeth with scorable proximal surfaces.
• Participants refrained from oral hygiene for 8-12 hours and avoided eating for 4 hours before each visit.
• Plaque levels were assessed using the Rustogi Modification of the Navy Plaque Index (RMNPI).
