In an embodiment of the disclosed technology, a toothbrush head formed of a bristled tread is rotatable about at least one vertically disposed sprocket. The toothbrush head has an elongated neck with sprockets extending axially therefrom. Bristles are wrapped around either or both sprockets. The bristles may be on a single belt wrapped around both sprockets. Alternatively, the bristles may extend from two spindles, each fitted around a sprocket. The sprockets rotate circumferentially within an upper head portion of the device. The bristles spin 360 degrees (full rotation) around the sprockets and within the stationary head. The head portion itself is replaceable or changeable, such that a handle portion may be used by multiple users or replaced.
