A portable toothbrush is provided to improve convenience of use without carrying the toothbrush and toothpaste together for a trip by forming a space filled with the toothpaste, at a grip part. In a method for combining the portable toothbrush and toothpaste, a head part(a) and a grip part(b) of the toothbrush are separably joined to each other. The toothpaste is injected into an empty space(c) of the grip part of the toothbrush and discharged through the rear side of the grip part when a user presses the grip part with hands. Therefore, the user does not have to carry the toothbrush and toothpaste together, when the user goes on a journey. |
