The invention relates to a toothbrush composed of the main body and the head comprising the bristle portion. The hellicoid axle contained into the main body propels, upon rotation of its base encountered on the external extremity of the toothbrush, the toothpaste towards the head portion destined for the cleaning of the teeth and the oral hygiene in general. The axle returns to its initial position upon inverse rotation of its external head. The disclosed herein toothbrush-and- toothpaste combinational assembly constitutes an one-piece easily transportable device for simple and fast oral cleaning. |
