Claim:
1. An oral care implement comprising: a housing extending along a longitudinal axis and configured for at least partial insertion into an oral cavity; a power source; a first array of positively charged conductive protrusions electrically connected to the power source, each of the positively charged conductive protrusions depending from a surface of the housing, the first array comprising a plurality of rows of the positively charged conductive protrusions that extend traverse to the longitudinal axis; and a second array of negatively charged conductive protrusions electrically connected to the power source, each of the negatively charged conductive protrusions depending from the surface of the housing, the second array comprising a plurality of rows of the negatively charged conductive protrusions that extend traverse to the longitudinal axis, wherein an electrical field is generated between the first array of positively charged conductive protrusions and the second array of negatively charged conductive protrusions; and wherein the plurality of rows of positively conductive protrusions alternate with the plurality of rows of negatively conductive protrusions in a direction substantially parallel to the longitudinal axis.
