Abstract
A method and apparatus are provided for whitening teeth using a fluid delivery toothbrush to deliver a bleaching liquid to the teeth during brushing. The fluid delivery toothbrush may be manual or powered, delivering fresh relatively high strength bleaching liquid to the tooth surfaces, preferably on a daily basis, for one to three minutes.
Claims4
A method for non-optically bleaching teeth consisting essentially of:
- a) providing a powered fluid delivery toothbrush having a brush and means for delivering a fluid to the brush, a reservoir for containing a non-abrasive bleaching liquid consisting essentially of a liquid peroxide and water, in fluid communication with the brush;
- b) placing the non-abrasive bleaching liquid in the reservoir;
- c) driving the brush for oscillation, rotation or vibration;
- and,
- d) treating the teeth for up to 3 minutes while driving the brush to scour the teeth while simultaneously delivering the bleaching liquid thereto, thereby increasing the reactivity of the bleaching liquid with any staining agent, the driven brush increasing mechanical action on the teeth during deposition of the bleaching liquid on the tooth surfaces;
- e) continuously delivering fresh bleaching liquid to the brush for spreading and working the bleaching liquid into and over the tooth surfaces to bleach the teeth;
- and,
- periodically repeating steps a-e.
