Great electric toothbrush and storage box for brush ends, which can also be detached from the charging base. The Oral-B 4000 brush has 4 different speeds and movements: whitening, sensitive, everyday use and gum care. In the box you will receive three different toothbrush heads for different actions: 1 CrossAction, 1 Sensitive, 1 3D White. In comparison to the 2000 model toothbrush – which I also own – it removes much more plaque and is more effective with teeth whitening. I would highly recommend buying this higher spec model than the 2000 as results are much better.
