According to the tooth bleaching apparatus 10 of the first embodiment, the following effects can be obtained.
(1) The tooth bleaching device 10 includes a generating device 30 and a mouthpiece 100. According to this structure, the user can hold | maintain the object in the position suitable for tooth bleaching by mounting | wearing the mouthpiece 100 which is an object which supplies a tooth bleaching fluid in an intraoral area. That is, the user can bleach the teeth without having to hold the object supplying the tooth bleaching fluid by hand. For this reason, the tooth bleaching apparatus 10 can provide the user with ease of use.

  (2) According to the configuration of (1) above, when the user is using the tooth bleaching apparatus 10, the user's hand is less likely to get tired. The tooth bleaching apparatus 10 also contributes to providing the user with ease in this respect.

  (3) According to the configuration of (1) above, the user can freely use his / her hand while using the tooth bleaching apparatus 10. This allows the user to perform other tasks while bleaching the teeth. The tooth bleaching apparatus 10 also contributes to providing the user with ease in this respect.

  (4) According to the configuration of the above (1), compared to the case where the user has an object for supplying the tooth bleaching fluid to the teeth by hand, the user is using the tooth bleaching apparatus 10 while the teeth are being used. The position of the first supply port 103 is difficult to shift. Therefore, the tooth bleaching fluid supplied from the first supply port 103 into the oral cavity is efficiently supplied to the teeth.

  (5) The generation device 30 includes a humidifier 33. According to this configuration, since the humidified gas is supplied from the mouthpiece 100 into the oral cavity, the oral cavity is difficult to dry even if the user does not separately supply moisture to the oral cavity. The tooth bleaching apparatus 10 also contributes to providing the user with ease of use in this respect.

  (6) The mouthpiece 100 includes a first supply port 103 and a second supply port 104 that are partitioned from each other. According to this configuration, the tooth bleaching fluid and the humidified gas are difficult to mix before being supplied into the oral cavity. For this reason, the possibility that the active ingredient contained in the tooth bleaching fluid is deactivated by mixing with the humidified gas is reduced. For this reason, compared with the case where the mouthpiece 100 does not include the first supply port 103 and the second supply port 104 that are partitioned from each other, the teeth are efficiently bleached.

  (7) The mouthpiece 100 includes a first supply passage 101 and a second supply passage 102 that are partitioned from each other. According to this configuration, the tooth bleaching fluid and the humidified gas are difficult to mix when passing through the inside of the mouthpiece 100.

For this reason, compared with the case where the mouthpiece 100 does not include the first supply passage 101 and the second supply passage 102 that are partitioned from each other, the teeth are efficiently bleached.

  (8) The radical species contained in the tooth bleaching fluid may be deactivated before acting on the teeth for various reasons. For example, if the tooth bleaching fluid and the humidified gas are mixed before being delivered into the oral cavity, the radical species may collide with water particles contained in the humidified gas and be replaced with another substance. Further, when the tooth bleaching fluid passes through the passage through which the humidified gas passes, radical species may be adsorbed by the moisture adhering to the wall surfaces of various objects from the humidified gas. On the other hand, the configurations (6) and (7) contribute to reducing the risk of deactivating radical species as described above. For this reason, compared with the case where the mouthpiece 100 does not include the above configuration (6) or (7), the tooth bleaching fluid is efficiently supplied to the teeth.

  (9) The tooth bleaching apparatus 10 includes a connecting portion 20. According to this configuration, since the user can wear the mouthpiece 100 even at a position away from the generating device 30, it is easy to take a relatively free posture when bleaching teeth. The tooth bleaching apparatus 10 also contributes to providing the user with ease in this respect.

  (10) When a tooth bleaching fluid is generated by generating corona discharge in a humidified gas, corona discharge may not occur due to condensation of the electrode. On the other hand, the tooth bleaching apparatus 10 supplies a gas that has not been humidified to the discharge unit 40. For this reason, the tooth bleaching fluid is efficiently generated by the discharge unit 40.

(Embodiment 5)
With reference to FIG. 7, the structure of the tooth bleaching apparatus 10 of Embodiment 5 is demonstrated. The tooth bleaching apparatus 10 according to the fifth embodiment includes the following configuration that is not clearly described in the description of the tooth bleaching apparatus 10 according to the fourth embodiment.

As shown in FIG. 19A, the tooth bleaching fluid is supplied from the first supply passage 21 of the connecting portion 20 to the inlet supply passage 50 </ b> A that is the first supply passage 501 of the mouthpiece 500. The tooth bleaching fluid in the first supply passage 501 is decelerated by flowing from the inlet supply passage 50A into the outlet supply passage 50B. The tooth bleaching fluid in the outlet supply passage 50B is supplied to the guide passage 506 from an intermediate portion of the first supply port 503. For this reason, the tooth bleaching fluid reaches the front teeth TF, and the teeth are bleached.

  Further, the humidified gas is supplied from the second supply passage 22 of the connecting portion 20 to the second supply passage 502 of the mouthpiece 500. The humidified gas in the second supply passage 502 is supplied to the guide passage 506 from an intermediate portion of the second supply port 504.

  As shown in FIG. 19B, the tooth bleaching fluid in the first supply passage 501 is supplied to the guide passage 506 from a portion closer to the end than the intermediate portion of the first supply port 503. For this reason, the tooth bleaching fluid reaches the back teeth TR, and the teeth are bleached.

  Further, the humidified gas in the second supply passage 502 is supplied to the guide passage 506 from a portion closer to the end than the intermediate portion of the second supply port 504. For this reason, humidified gas reaches the gum G which exists in the root of the back tooth TR, and the dryness of the organ is suppressed.

  The tooth bleaching fluid in the guide passage 506 flows through the guide passage 506 along the teeth by being guided by the guide surface 521 of the outer curved element 520. For this reason, the tooth bleaching fluid reaches approximately all of the upper and lower teeth and is bleached. Further, the humidified gas in the guide passage 506 flows through the guide passage 506 so as to follow the teeth by being guided by the guide surface 521 of the outer curved element 520. For this reason, the humidified gas reaches almost all of the upper gum G and the lower gum G, and drying of those organs is suppressed.

  According to the tooth bleaching apparatus 10 of the ninth embodiment, in addition to the effects (1) to (12) and the effects (14) to (23) obtained by the tooth bleaching apparatus 10 of the eighth embodiment, Furthermore, the following effects can be obtained.

  (24) According to the mouthpiece 500, the outlet supply passage 50B is formed inside the occlusal element 560, and the first supply port 503 is opened on each of the upper side 561 and the lower side 562 of the occlusal element 560. According to this configuration, when the tooth bleaching fluid inside the mouthpiece 500 passes through the outlet supply passage 50B and the first supply port 503, the flow direction of the tooth bleaching fluid changes greatly. For this reason, the tooth bleaching fluid tends to stay in the outlet supply passage 50B. For this reason, the active ingredient existing in the outlet supply passage 50B is likely to diffuse into the tooth bleaching fluid. For this reason, the tooth bleaching fluid having a small difference in the concentration of the active ingredient is supplied from the first supply port 503 to the guide passage 506. For this reason, it is hard to produce a difference in the degree of bleaching in each part of one tooth and the degree of bleaching in different teeth.

  (25) The outlet supply passage 50B is formed inside the occlusal element 560. According to this configuration, as compared with the case where a passage having the same volume as the outlet supply passage 50B is formed inside the outer bending element 520, there is a large room for setting the thickness of the outer bending element 520 to be thin. When the thickness of the outer bending element 520 is set to be thin, the user can easily wear the mouthpiece 500.
