Therefore, the doctor for the tooth management having the second terminal 220 can check the current tooth condition of the user, and can provide the prescription and dental visit time according to the tooth condition to the user.

Also, it is possible to determine the change in the color of the teeth of the user and the increase / decrease of tartar present in the teeth of the user of the toothbrush 100 for tooth care, and to transmit them to the doctor.

In addition, by photographing the part of the tongue in the tongue, information can be secured and the health status can be confirmed.

In addition, comparative analysis is possible according to the change of the gums. When the gum is damaged, the gums are drowned, drowned, and inflamed. From the image acquired before brushing, the distance between the top of the tooth and the top of the gingiva is measured, and the changed value is compared daily, so that the damage of the gum can be grasped and the doctor can be treated at the appropriate time.

By using the tooth care toothbrush and the tooth management system according to an embodiment of the present invention, information on whether or not the user's dental calculus is increased or decreased through the toothbrushing pattern information and the teeth photographed image is transmitted and downloaded between the user and the doctor in real time Communication between the patient and the doctor can be made about the prescription information and the dental treatment timing according to the tooth condition.

In addition, since the information on the color change of the user's teeth can be periodically transmitted to the doctor, the user's teeth whitening treatment need and the color change of the user's teeth after the whitening treatment are discriminated and transmitted to the doctor, It can be effectively used for whitening treatment.
