I have tested this new brush head for two months and was actually immediately convinced of the cleaning effect. As already indicated in another review, so I turned and found that the However, the Diamond Clean brush heads not such a big cleaning action between the teeth. Gradually I therefore noticed more and more dental calculus and after the forthcoming visit to the dentist, I switched back to the ProResults brush head. The difference was then made very clear. The latter brush head is much better in the interdental spaces, the tartar growth is back on the old minimum level.
