Abstract

In the inventive method, a tooth whitener having a concentration of hydrogen peroxide significantly lower than the concentration typically used in in-office applications is applied to the teeth in gel form. Next, thin transparent film is placed over the teeth to seal the tooth whitener onto the teeth. The film creates a closed system that precludes oxygen from migrating away from the teeth into the atmosphere. A white light in the range of 380-660 nm wavelength is then activated to assist in exciting oxygen in the path of the light and the oxygen molecules bombard the tooth surfaces. The oxygen molecules may not easily escape from the tooth surfaces into the atmosphere due to the wrap and, thus, their whitening “power” is enhanced and lengthened. Then, the patient may stabilize the whitening results over a 7 to 10 day regime using a lower concentration tooth whitener.

Claims (31)

1. A method of tooth whitening, including the steps of:

a) applying a tooth whitener to at least one tooth of a patient;

b) enclosing said tooth and whitener within a flexible transparent wrap to create a chamber containing said tooth and whitener, then shining a light onto said tooth through said wrap for a desired time period;

c) maintaining said wrap enclosing said tooth and whitener for a desired period of time;

d) removing said wrap; and

e) rinsing said whitener off said tooth.

2. The method of claim 1 , wherein said at least one tooth comprises a plurality of teeth.

3. The method of claim 1 , wherein said light comprises a white light having a wavelength of 380-660 nm.

4. The method of claim 3 , wherein said white light is shone on said tooth for a period of 10 minutes.

5. The method of claim 4 , wherein after said 10 minute period, said white light is shone on said teeth for a second 10 minute period.

6. The method of claim 1 , wherein said flexible wrap is made of a material chosen from the group consisting of polypropylene, polyethylene, SARAN® wrap, and an edible material.

7. The method of claim 1 , wherein said tooth whitener includes 15-99%, by weight, of a substance made up of, by weight, 80-83% water-soluble polyvinylpyrrolidone and 17-20% hydrogen peroxide; 0.2-1%, by weight, oil of wintergreen, and balance ethanol.

8. The method of claim 1 , wherein said tooth whitener comprises a gel.

9. A method of tooth whitening, including the steps of:

a) applying a gel tooth whitener to a patient's teeth;

b) enclosing said teeth and whitener within a transparent flexible wrap to create a chamber containing said teeth and whitener;

c) maintaining said wrap enclosing said teeth and whitener for a desired period of time;

d) during said desired period of time, shining a white light on said teeth through said transparent wrap;

e) removing said wrap; and

f) rinsing said whitener off said teeth.

10. The method of claim 9 , wherein said white light has a wavelength of 380-660 nm.

11. The method of claim 9 , wherein said desired period of time comprises a first 10 minute period followed by a second 10 minute period.

12. The method of claim 9 , wherein said tooth whitener includes 15-99%, by weight, of a substance made up of, by weight, 80-83% water-soluble polyvinylpyrrolidone and 17-20% hydrogen peroxide; 0.2-1%, by weight, oil of wintergreen, and balance ethanol.

13. The method of claim 12 , wherein said flexible wrap is made of a material chosen from the group consisting of polypropylene, polyethylene, SARAN® wrap, and an edible material.

14. The method of claim 9 , wherein said flexible wrap is made of a material chosen from the group consisting of polypropylene, polyethylene, SARAN® wrap, and an edible material.

15. A method of tooth whitening, including the steps of:

a) applying a tooth whitener to at least one tooth of a patient, said tooth whitener including 15-99%, by weight, of a substance made up of, by weight, 80-83% water-soluble polyvinylpyrrolidone and 17-20% hydrogen peroxide; 0.2-1%, by weight, oil of wintergreen, and balance ethanol;

b) enclosing said tooth and whitener within a flexible wrap to create a chamber containing said tooth and whitener;

c) maintaining said wrap enclosing said tooth and whitener for a desired period of time;

d) removing said wrap; and

e) rinsing said whitener off said tooth.
