The toothpaste storing tube filled with toothpaste and the toothpaste storing tube are detachably assembled with the interior of the trunk constituted in the toothbrush bar, and then the toothpaste storing tube and the toothpaste storing tube can be drawn out in use so as to dispense toothpaste to the toothbrush bristles. Therefore, the user can brush his/her teeth. When toothpaste is consumed, toothpaste can be again supplied to the toothbrush storing tube so that the user can use it until the bristles are deteriorated. Therefore, resources can be saved and toothpaste can be hygienically kept.
