Title: Electric toothbrush head replacement system and method

Abstract: A system and method for enabling the replacement of electric toothbrush heads on toothbrush models that require users to replace the entire toothbrush head assembly is described. Toothbrush head assemblies typically include much more than a simple toothbrush head, for example, a shank attached to magnets and a housing for coupling the shank to the toothbrush base. The present invention therefore permits the replacement of worn out toothbrush heads instead of entire toothbrush head assembly that includes many parts that have not worn out. The system includes tools for separating an existing toothbrush head from a shank and replacement toothbrush heads having new bristles that couple with the shank or the head assembly of a particular toothbrush model.
