A toothbrush has a toothbrush body, and a handle part wherein a toothpaste container can be removably inserted therein. The toothpaste container has a handle shell part which, with the toothpaste container inserted into the handle part, forms part of the outer surface of a handle. The toothpaste container essentially maintains its form during teeth cleaning and transmits loading which occurs, irrespective of the filling level of the toothpaste container of the toothbrush. The mounting of the toothpaste container on the toothbrush body allows very straightforward and quick removal and opening or insertion and closure of the toothpaste container. The container holder is provided with a closure pin, wherein when the toothpaste container is inserted into the handle part, a sealed closure of the toothpaste container is ensured. With the toothpaste container removed from the handle part, it is possible for toothpaste to be squeezed out of the toothpaste container.
