A disposable or edible chewable toothbrush is disclosed for cleaning teeth between meals. The device includes a chewable bristle holder with bristles attached to the holder, a cavity formed within the holder, a substance within the cavity, and regions of weakness formed in the holder that prevent leakage of the contents of the holder until the device is compressed by chewing. In another embodiment, a disposable or edible brush is housed inside within a disposable or edible shell. Upon chewing, the shell is broken or dissolves thereby releasing its contents, which include the brush and possibly a dentifrice.
