The toothbrush also contains a handle portion, which is attached to the receiving portion at the opposite side of the head portion. The handle portion contains a plunger and a sliding button configured such that the plunger is located inside the head portion and is capable of sliding in and out of said head portion and receiving portion. A paste cartridge containing paste and having a hole and a stopper located at opposite ends is placed in the receiving portion such that the hole of the paste cartridge is connected to the head portion of the device.
