Abstract
A method for whitening teeth is disclosed. The method includes supplying a liquid sufficient to at least partially submerge a portion of a tooth; positioning a plasma device adjacent to the submerged portion of the tooth; supplying ionizable media to the plasma device; and igniting the ionizable media at the plasma device sufficient to form a plasma effluent in the presence of the liquid at the distal portion, whereby the plasma effluent reacts with the liquid to form at least one reactive species that interacts selectively with foreign matter disposed on the tooth.
