Identification
Oral-B uses “Type numbers” to identify their large catalog of electric toothbrushes. Type numbers are usually a more effective way to locate repair and service information for your specific toothbrush.
Note that the packaging or box might also list a Type number, like “Type 3757.” This is the Type number for the charger, not the toothbrush. To learn more about Oral-B Type numbers, visit their support site. The type number (4729) can be found on the bottom of the brush. It has Braun and Oral-B branding on the face of the brush.
