Enables electric toothbrush head replacement on models that require users to replace entire toothbrush head assemblies. The head assemblies 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. Allows for replacement of a worn out toothbrush head instead of the entire toothbrush head assembly that includes many parts are not worn out. Although selling entire head assemblies may increase the manufacturer's margin, this practice of selling more than is needed is wasteful, environmentally unfriendly and more costly to the user. Includes tools for separating an existing toothbrush head from a shank and replacement heads that fit the shank of a particular toothbrush model.
