6. The whitening light of claim 5 , wherein the first charging mechanism is positioned on a first side of the rear portion of the whitening light, and wherein the second charging mechanism is positioned in the cavity at a location that corresponds to the first charging mechanism when the whitening light is positioned in the cavity of the case.

7. The whitening light of claim 6 , wherein the button is located on a second side of the rear portion opposite the first side.

8. The whitening light of claim 6 , wherein the first charging mechanism is aligned with the second charging mechanism when the whitening light is positioned in the cavity of the case.

9. The whitening light of claim 8 , wherein the first charging mechanism and the second charging mechanism comprise respective charging plates that form an electrical contact when the whitening light is positioned in the cavity of the case, and wherein the power from the case is transferred via the second charging mechanism through the electrical contact to the first charging mechanism to charge the whitening light.

10. The whitening light of claim 1 , wherein the first light array is separated from the second light array by a distance in the range of 8 to 10 millimeters.

11. A whitening light comprising:

a mouthpiece having a light array arranged along the mouthpiece for directing light onto an exposed portion of a plurality of teeth of a user; and

a rear portion comprising a first power source and a first charging mechanism, the first power source communicably coupled to the light array, the first charging mechanism configured to receive power transferred from a second charging mechanism located on a case for the whitening light, wherein the first power source comprises a rechargeable battery configured to be charged by the second charging mechanism, the rechargeable battery configured to be charged to a power output sufficient to power the whitening light to emit light configured to whiten teeth upon selection of a button on the rear portion of the whitening light to commence a treatment session, to emit the light for a predetermined duration corresponding to a duration of the treatment session, and to automatically switch the light array to an off-setting following expiration of the predetermined duration.

12. The whitening light of claim 11 , wherein the case further comprises a second power source and a cavity sized to receive the mouthpiece, and wherein the second charging mechanism is communicably coupled to the second power source and configured to electrically couple with the first charging mechanism to transfer power from the second power source to the first power source when the whitening light is positioned in the cavity.

13. The whitening light of claim 11 , wherein the light array includes at least ten lights arranged to direct light onto at least ten lower teeth and at least ten lights arranged to direct light onto at least ten upper teeth.

14. The whitening light of claim 11 , wherein the mouthpiece and the rear portion together define a profile of the whitening light that matches a shape of a cavity of the case.

15. The whitening light of claim 14 , wherein the first charging mechanism is positioned on a first side of the rear portion of the whitening light, and wherein the second charging mechanism is positioned in the cavity at a location that corresponds to the first charging mechanism when the whitening light is positioned in the cavity of the case.

16. The whitening light of claim 15 , wherein the first charging mechanism is aligned with the second charging mechanism when the whitening light is positioned in the cavity of the case.

17. The whitening light of claim 16 , wherein the first charging mechanism and the second charging mechanism comprise respective charging plates that form an electrical contact when the whitening light is positioned in the cavity of the case, and wherein the power from the case is transferred via the second charging mechanism through the electrical contact to the first charging mechanism to charge the whitening light.

18. The whitening light of claim 14 , wherein the button is located on a second side of the rear portion opposite the first side.

19. The whitening light of claim 11 , wherein the light array is a first light array and the first light array is separated from a second light array by a distance in the range of 8 to 10 millimeters.

20. A whitening light comprising:

a mouthpiece having a light array arranged along the mouthpiece for directing light onto an exposed portion of a plurality of teeth of a user; and

a rear portion comprising a first power source and a first charging mechanism including a first charging plate, the first power source communicably coupled to the light array, the first charging mechanism configured to receive power transferred via the first charging plate from a second charging plate of a second charging mechanism located on a case for the whitening light, wherein the power is transferred from the second charging plate to the first charging plate responsive to the first charging plate and the second charging plate forming an electrical contact when the whitening light is positioned in the case, wherein the first power source comprises a rechargeable battery configured to be charged by the second charging mechanism, the rechargeable battery being charged to a power output sufficient to power the whitening light to emit light configured to whiten teeth upon selection of a button on the rear portion of the whitening light to commence a treatment session, to emit the light for a predetermined duration corresponding to a duration of the treatment session, and to automatically switch the light array to an off-setting following expiration of the predetermined duration.
