  • Patent number: 8185999
    Abstract: An oral care implement or toothbrush 100 includes a head 104, a tooth cleaning element region 116 and a tissue cleaning element region 114. The tissue cleaning element region 114 includes a plurality of flexible, angled projections 120. The projections 120 are configured to flex from an at-rest position to a substantially flat position when the tissue cleaning element region 114 is in contact with the tongue and is pushed into the mouth. The projections 120 are also configured to flex to a substantially upright position when the tissue cleaning element region 114 is in contact with the tongue and is pulled out of the mouth. This arrangement aids in preventing debris from being pushed into the mouth and in removing debris from the mouth and tongue. The flexible projections 120 may be used in conjunction with rigid projections 122 having a generally vertical configuration to aid in removing debris from the mouth and in engaging the cheek to improve saliva production during brushing.

  • Patent number: 8156602
    Abstract: A device for generating a chemical agent in situ on an as-needed basis via the application of an electrical potential across a pair of conductors in communication with an electrolyte. The device may be a toothbrush that generates chemical agents in a user's mouth by applying an electrical potential to an electrolyte such as saliva and/or a dentifrice located therein. The chemical agents may include ozone, hydrogen peroxide, peroxide, chlorine and/or hypochlorite. The toothbrush may include a voltage source and a first set of electrodes for applying an electrical potential to the electrolyte. The toothbrush may also include a second set of electrodes disposed about an anode of the first set of electrodes. The first and second sets of anodes cooperate to produce ions, peroxides, ozone and/or other chemical agents via the application of electrical potential to the electrolyte.
