Abstract
A fluid delivery powered toothbrush utilizes a removable/disposable neck assembly that contains a fluid reservoir, a fluid delivery system and a fluid path therein leading to a brush receptacle. No fluid is used in or passes through the toothbrush handle. Preferably a pump is located in the neck assembly and activated at the same time as the brush drive such that fluid is delivered during brushing. In one embodiment of the invention, the brush is replaced with a nozzle for providing fluid prior to or after brushing. The components for the neck assembly are disposable to minimize cross-contamination while enhancing fluid delivery to the teeth during brushing.
