A pump element is located in the brushhead and is configured so that the back and forth movement of the brushhead in operation results in fluid moving from the reservoir to a dispensing valve located in the brushhead. The dispensing valve has an end portion which is normally closed, opening under pressure of fluid from the pump. The refilling assembly is separated from the toothbrush and is configured to fit over the top of the toothbrush. A pump used in a power toothbrush for fluid delivery to the bristles. The pump includes a pump chamber with a piston ball located therein. The pump includes a fluid exit channel which connects the discharge end of the pump chamber with an opening in the brushhead in which the dispensing valve is located.
