Mouthpiece

Abstract

A mouthpiece of the present invention includes a light irradiation section that irradiates the front surfaces of teeth with light having a predetermined wavelength, and the light irradiation section has a blue light emitting diode or ultraviolet light emitting diode. The mouthpiece is attached to the teeth and the front teeth are irradiated with a blue light or ultraviolet light emitted by the light emitting diode, thereby performing teeth whitening processing.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a mouthpiece, and particularly relates to a mouthpiece that is suitable for performing so-called whitening processing for whitening teeth. [0003] 2. Description of the Related Art [0004] In general, as an apparatus that performs teeth whitening processing, one that is disclosed in Unexamined Japanese Patent Publication No. 2003-242806 is known. The conventional whitening processor irradiates teeth with ultraviolet rays using a halogen lamp to perform teeth whitening processing. [0005] However, in the method in which the teeth are irradiated with ultraviolet rays using the halogen lamp to perform teeth whitening processing, since the ultraviolet rays emitted by the halogen lamp had high light intensity, there was difficulty in handling the ultraviolet rays. For example, when irradiation was continued for a long time, there was a possibility that the surfaces of the teeth and gums arou...

AI Technical Summary

Benefits of technology

[0006] An object of the present invention is to provide a mouthpiece that can easily and safely perform teeth whitening processing at home.

[0008] According to the present invention, in the case where teeth whitening processing is performed, the mouthpiece is put in the mouth to irradiate the teeth with the blue light or ultraviolet light from the light emitting diode of the light irradiation section. In this way, since the teeth is irradiated with the blue light or ultraviolet light from the light emitting diode, light intensity is small as compared with irradiation of the ultraviolet rays from the halogen lamp, and this brings about safety without the possibility that the surfaces of teeth and the gums around the teeth will be damaged. Further, since the handling is easy, teeth whitening processing can be easily performed at home. Moreover, since the blue light emitting diode or ultraviolet light emitting diode is attached to the mouthpiece, the mouthpiece is only put in the mouth to make it possible to easily perform whitening processing.

[0009] Furthermore, according to the present invention, the mouthpiece claim 1 further includes a horseshoe main body attached to an oral cavity, and a belt-like flexible substrate embedded along the horseshoe shape of the main body. The light irradiation section is desirably attached to the flexible substrate. In this way, since the flexible substrate is embedded in the main body of the mouthpiece, the mouthpiece has high water resistance to the light emitting diode and can be washed with water.

[0010] Furthermore, according to the present invention, the flexible substrate desirably faces the front teeth when being attached to the oral cavity and multiple light emitting diodes are desirably provided in a longitudinal direction of the flexible substrate, and at least the entirety of the front teeth is desirably irradiated with the blue light or ultraviolet light. In this way, since the multiple light emitting diodes are provided in the longitudinal direction of the flexible substrate, the entirety of the front teeth can be irradiated with the blue light or ultraviolet light to eliminate the need for performing light irradiation for each tooth to make it possible to perform whitening processing effectively.

[0011] Still furthermore, according to the present invention, the light irradiation section desirably sets multiple irradiation time to be selectable by a switch. In this way, the user can select the preset irradiation time to make it possible to adjust irradiation time according to the individual's teeth state.

Problems solved by technology

However, in the method in which the teeth are irradiated with ultraviolet rays using the halogen lamp to perform teeth whitening processing, since the ultraviolet rays emitted by the halogen lamp had high light intensity, there was difficulty in handling the ultraviolet rays.

For example, when irradiation was continued for a long time, there was a possibility that the surfaces of the teeth and gums around the teeth would be damaged, and a fixed skill was required for the ultraviolet irradiation and the help of a specialist such as a dentist was needed.
