ORAL CARE DEVICE AND METHOD

An oral care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic c...

More Information
Summary:An oral care device has a field generator adapted to generate an electric field in a mouth of a user, responsive to an input control signal. The electric field is for imparting a force upon particles forming a biofilm to be removed by the oral care device or upon cleaning agent particles. A cyclic control signal is generated for intermittent generation of an electric field at a first RF frequency. The use of an intermittent generation of an RF electric field means the force applied to particles (in particular polarized particles) by the field is itself cyclic. The cyclic nature of this applied force is found to be more effective in the disintegration of a biofilm to be removed, and hence makes subsequent mechanical removal, e.g. by brushing, easier.
