Many electric toothbrushes come with an assortment of heads – or it is possible to obtain different heads. For example, Oral-B offer Cross-Action, Sensitive, Kids, Whitening, Precision Clean, Floss Action and TriZone heads suitable for use across their range of electric toothbrushes. This allows you to tailor the brush head characteristics to your precise circumstances.
If you have shared an electric brush unit you will need to swap heads for different users. Most brushes offer a way of colour coding brush heads through plastic rings that can be swapped for different users. It is possible to buy dedicated electric toothbrush head racks which keep the heads in pristine condition when not in use.
