Abstract
Abstract A tooth brush has a hollow open ended handle section for receiving a spool of dental floss. A removable cap member for closing the handle section has a cutting blade embedded in the cap member within the confines of the outer surface thereof and adjacent a cutaway portion in such outer surface. The handle section and cap member are relatively formed to provide for the withdrawal of dental floss from the handle section and across the outer surface of the cap member for severance at the cutting member.
