• the invention relates to an electric toothbrush with a handle and an attachment, wherein the handle has a housing in which a reservoir for a care substance, a pump for conveying the care substance and a drive unit for driving the pump are arranged.
• an electric toothbrush which comprises a handpiece and an attachment with a brush head which is driven by a first electric motor arranged in the handpiece.
• a reservoir is arranged within the hand part of the electric toothbrush, which is connected via a pump to a channel which opens into the brush head.
• the pump is driven by a second electric motor continuously or at predetermined intervals, wherein the first and the second electric motor are powered by a battery or an accumulator with energy.
• an electric toothbrush with a handle and an attachment, wherein the handle has a housing which is divided by a running in the longitudinal direction of the housing partition into a liquid-tight first chamber and a second chamber, wherein in the second chamber a reservoir for a care substance and a pump and in the first chamber, a drive unit for the pump are arranged.
• the second chamber of the housing is accessible from the outside via a resealable cover.

• a liquid or pasty agent for the treatment of the oral cavity may include, for example, substances for cleaning the teeth and means for Caries prevention, treatment of tooth decay, reduction of bad breath, bleaching or whitening of teeth, remineralization of dentin, or desensitization of sensitive teeth.
• these may contain two different substances, which may be conveyed in parallel by two pumps. This is particularly advantageous when several substances are to be used for oral care, which can not be stored together, otherwise they would react with each other. Due to the separate storage in two storage containers and parallel delivery by means of two pumps, these substances mix only in the mouth, and can be administered simultaneously. In addition, there may be positive effects when two substances in the mouth react with each other.
• the reservoir is preferably made of a replaceable flexible film bag having, for example, a multilayer structure of metal and plastic films, and preferably has an elongate, flat shape.
• the pump can optionally be controlled by the user via a control knob or by an electronic circuit.
