<p>Enables electric toothbrush head replacement on models that require users to replace entire toothbrush head assemblies (100). The head assemblies include much more than a simple toothbrush head (101), for example a shank (102) attached to magnets and a housing (103) 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 that are not worn out. Includes tools for separating an existing toothbrush head from a shank and replacement heads that fit the shank of a particular toothbrush model.</p> |
