A toothbrush with a flexible head is disclosed. At least the head of the toothbrush may be manufactured by in-molded technology. A blend of thermoplastic elastomer and polypropylene is used to impart added flexibility to the head. That flexibility is further enhanced by the tapered profile of the head. Cleaning elements may be secured in place during manufacture using in-molded techniques or staples.
