Abstract

A teeth whitening system including a thermally conductive mouthpiece that carries a teeth whitening agent and that is connected to a thermally-chargeable heat sink. The system controls the flow of thermal energy from the heat sink in order to provide thermal activation of whitening agent. The system may include a catalytically-enhanced teeth whitening device for receiving the whitening agent and promoting enhanced teeth whitening by the whitening agent. The teeth whitening device may be used with or without the application of supplemental heat or light for further augmenting whitening reactions of the whitening agent. The teeth whitening device may include a substrate that may be fabricated from a catalytic agent useful for enhancing tooth whitening by the teeth whitening agent. Alternatively, the substrate may be covered, coated, impregnated or otherwise contacted by a catalytic agent in an amount effective to enhance tooth whitening by the teeth whitening agent.

Claims

1. A teeth whitening system, comprising:

a heating module including a thermally-chargeable heat sink that is chargeable to a desired operating temperature by a heating source and removed from the heating source during a teeth whitening treatment;

a mouthpiece thermally and adjustably connected to said heat sink such that the rate and intensity of heat is controllably transferred from said heat sink to said mouthpiece; and

a heat-activated whitening agent disposed in said mouthpiece such that said agent contacts a user'"'"'s teeth, whereby when heat is transferred from said heat sink to said mouthpiece said agent is activated and whitens the user'"'"'s teeth.

2. The teeth whitening system of claim 1 further comprising a connector having a first end connected to said mouthpiece and a second end received by said heat sink.

3. The teeth whitening system of claim 2 wherein said connector is slidably connected to said heating module whereby said second end of said connector is selectively insertable at desired distances into said heat sink.

4. The teeth whitening system of claim 2 wherein said connector is threadedly connected to said heating module whereby said second end of said connector is selectively insertable at desired distances into said heat sink.

5. A method for whitening teeth comprising the steps of:

providing a heating module including a thermally-chargeable heat sink;

charging the heat sink to a desired operating temperature by a heating source;

removing the heat sink from the heating source;

inserting a mouthpiece that is thermally and adjustably connected to the heat sink into a mouth of a user, wherein the mouthpiece has applied thereto a heat-activated whitening agent; and

adjusting the position of the mouthpiece relative to the heat sink to control the rate and intensity of heat that is transferred from the heat sink to the mouthpiece.

6. The teeth whitening method of claim 5 further comprising a providing connector having a first end connected to the mouthpiece and a second end adjustably received by the heat sink.

7. The teeth whitening method of claim 6 further comprising slidably connecting the connector to the heating module whereby the second end of the connector is selectively insertable at desired distances into the heat sink.

8. The teeth whitening method of claim 6 further comprising threadedly connecting the connector to the heating module whereby the second end of the connector is selectively insertable at desired distances into the heat sink.

9. A teeth whitening device comprising a substrate fabricated from a catalytic agent that is operable to generate active peroxide species that are useful for whitening teeth when the catalytic agent is contacted by a peroxide-containing teeth whitening agent.

10. The teeth whitening device of claim 9 wherein said catalytic agent is selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum and aluminum.

11. The teeth whitening device of claim 9 wherein said catalytic agent is a metal alloy including aluminum and a metal selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum.

12. The teeth whitening device of claim 9 wherein said catalytic agent is an oxide of a metal selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum and aluminum.

13. A teeth whitening device comprising:

a substrate;

a catalytic agent in contact with said substrate, said catalytic agent being operable to generate active peroxide species that are useful for whitening teeth when the catalytic agent is contacted by a peroxide-containing teeth whitening agent.

14. The teeth whitening device of claim 13 wherein said catalytic agent is selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum and aluminum.

15. The teeth whitening device of claim 13 wherein said catalytic agent is a metal alloy including aluminum and a metal selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum.

16. The teeth whitening device of claim 13 wherein said catalytic agent is an oxide of a metal selected from the group of metals consisting of platinum, palladium, gold, iridium, silver, nickel, titanium, manganese, molybdenum and aluminum.

17. The teeth whitening device of claim 13 wherein said substrate is rigid.
