Abstract
The two-in-one toothbrush provides for dual sets of brushing bristles facing in opposing directions to allow the toothbrush to clean both the upper and lower teeth simultaneously. Another form of the toothbrush design allows for the movement of at least one set of brushing bristles between extended and retracted positions, for use and hygienic storage of the brushing bristles. In another form, the toothbrush design allows for the independent movement of dual sets of brushing bristles between extended and retracted positions, for use and hygienic storage of the brushing bristles.
