ORAL CARE DEVICE AND METHOD

摘要

An oral care device (8) for use in aiding delivery of a substance for an oral treatment purpose within the mouth. The device comprises a field generator (16) which is adapted to generate a field (20) for exerting a force on particles (20) susceptible to the field to guide movement of the particles to a desired location. When operated in the mouth, this allows oral treatment particles to be quickly, safely and efficiently distributed within the mouth to the correct locations for performing the oral treatment function.
