Beyond the Bristles:

New study shows the Waterpik® Sensonic®Professional Toothbrush removes 80% of plaque without bristle contact.

Independent researchers recently evaluated whether four popular sonic toothbrushes could remove plaque without direct bristle contact. Findings showed that the Waterpik® Sensonic® removed 80% of the plaque at a distance of 2mm beyond the bristles, making it nearly 30% more effective than its nearest competitor, Sonicare®Flexcare. Plaque that was once unreachable or missed through traditional brushing is now easily removed with the Sensonic® advanced sonic cleaning action.

The new research was published in the Journal of Clinical Oral Investigations, sponsored by a grant from the Swiss Society of Dentistry. According to the researchers, toothbrushes utilizing high-speed side-to-side actions may generate an acoustic transfer of energy and thermodynamic surface tension forces that in turn agitate air molecules and contribute to plaque removal beyond the reach of the bristles.

Efficacy of various side-to-side toothbrushes for noncontact biofilm removal

Schmidt JC et al. Clin Oral Invest, 2014; 18:793-800. Study conducted at University of Basel, Switzerland


To evaluate the efficacy of the Waterpik® Sensonic® Professional Toothbrush to other sonic powered toothbrushes for noncontact (beyond the bristles) biofilm removal.


Plaque biofilm was formed in vitro on protein-coated titanium disks and was exposed to four different side-to-side sonic toothbrushes using brushing times of 2, 4, and 6 seconds and brushing (bristle-to-disk) distances of 0, 2, and 4 mm. The biofilm volumes were measured using volumetric analyses with confocal laser scanning microscope images to determine biofilm removal.


The overall median reduction in plaque biofilm for the Waterpik® Sensonic® Professional Toothbrush was 80%, while the median reduction for the Sonicare® FlexCare was 62%. The other two toothbrushes in the study removed 9% and 13% respectively.


The Waterpik® Sensonic® Professional Toothbrush removed more in vitro plaque without bristle contact than Sonicare® FlexCare.
