Abstract

Various apparatus and methods for cleaning teeth and gingival pockets are disclosed herein. A fluid platform can include a pressure wave generator configured to propagate pressure waves through a treatment fluid. The pressure waves may be sufficient to remove undesirable dental deposits from a treatment tooth, neighboring gums, and/or spaces between the tooth and gums.

Claims (34)

1. A system for treating an exterior surface of one or more teeth or gum tissue in a mouth of a mammal, the system comprising:

a mouthpiece sized and shaped to be inserted into the mouth and to conform to a maxillary or mandibular arch, the mouthpiece including one or more fluid ports;

a fluid motion source in fluid communication with the mouthpiece, the fluid motion source configured to deliver a substantially degassed liquid to the mouth and to remove liquid from the mouth through the one or more ports; and

a pressure wave generator coupled with the mouthpiece and configured to generate pressure waves through the substantially degassed liquid, the generated pressure waves having multiple frequencies and a broadband frequency spectrum,

wherein the fluid motion source is operable to create movement of liquid to and

from the mouth through the one or more ports at variable frequencies.

2. The system of claim 1 , wherein the fluid motion source is configured to create oscillatory movement of liquid to and from the mouth at a first frequency range during a first treatment phase and at a second frequency range during a second treatment phase.

3. The system of claim 2 , wherein the second frequency range includes higher frequencies than the first frequency range.

4. The system of claim 3 , wherein a volume of liquid moving to and from the mouth during the first treatment phase is larger than a volume of liquid moving to and from the mouth during the second treatment phase.

5. The system of claim 4 , wherein the first treatment phase is performed before the second treatment phase.

6. The system of claim 3 , wherein the fluid motion source is configured to create oscillatory movement of liquid to and from the mouth at frequencies that increase over time from a first frequency in the first frequency range to a second frequency in the second frequency range.

7. The system of claim 3 , wherein the fluid motion source is configured to randomly change the frequencies of the oscillatory movement of liquid to and from the mouth.

8. The system of claim 3 , wherein the first treatment phase at least partially overlaps the second treatment phase.

9. The system of claim 3 , wherein the first frequency range includes frequencies in a range of about 0.1 Hz to about 20 kHz.

10. The system of claim 3 , wherein the second frequency range includes frequencies in a range of about 20 kHz to about 1,000 kHz.

11. The system of claim 1 , wherein the mouthpiece comprises a switch configured to activate the fluid motion source.

12. The system of claim 1 , further comprising a fluid driver and a control mechanism configured to control the operation of the fluid driver.

13. The system of claim 12 , wherein the control mechanism is configured to balance an amount of liquid delivered to the mouth and removed from the mouth during a cleaning procedure.

14. The system of claim 13 , wherein the control mechanism is configured to at least partially fill the mouth with liquid in a start-up phase of a treatment procedure.

15. The system of claim 1 , wherein the pressure wave generator comprises a laser device.

16. The system of claim 1 , wherein the pressure wave generator comprises a liquid jet device.

17. The system of claim 1 , wherein the substantially degassed liquid comprises a whitening solution.

18. The system of claim 1 , wherein the substantially degassed liquid has less than about 5% dissolved oxygen or air by volume.

19. A method for cleaning an exterior surface of one or more teeth or gum tissue in a mouth of a mammal, the method comprising:

inserting a mouthpiece into the mouth, the mouthpiece conforming to a maxillary or mandibular arch;

activating a fluid motion source that is in fluid communication with the mouthpiece to deliver a substantially degassed liquid to the mouth and to remove liquid from the mouth;

creating oscillatory movement of liquid to and from the mouth through the one or more ports at variable frequencies; and

generating pressure waves through the substantially degassed liquid, the generated pressure waves having multiple frequencies and a broadband frequency spectrum.

20. The method of claim 19 , wherein creating movement comprises performing a first treatment phase to create oscillatory movement of liquid to and from the mouth at a first frequency range and performing a second treatment phase to create oscillatory movement of liquid to and from the mouth at a second frequency range.

21. The method of claim 20 , wherein the second frequency range includes higher frequencies than the first frequency range.

22. The method of claim 21 , wherein the first frequency range includes frequencies in a range of about 0.1 Hz to about 20 kHz.

23. The method of claim 21 , wherein the second frequency range includes frequencies in a range of about 20 kHz to about 1,000 kHz.

24. The method of claim 19 , the mouthpiece including one or more fluid ports, the method including delivering the substantially degassed liquid through the one or more ports.

25. The method of claim 19 , wherein the substantially degassed liquid has less than about 5% dissolved oxygen or air by volume.
