A kind of "special polishing tool"! Dissolves stubborn deposits, but feels "hard" to. (Made in Germany.)

In addition to the deep-cleaning brush (formerly Micro-Pulse) and the "ordinary" Precision Clean, I've still got started a long-term experiment with this model, because I was very excited after the first use of this 3D WHITE.

I turn to this "polishing brush" in combination with the Biorepair toothpaste, 75 ml, which I can recommend, incidentally, in the context, once a week.
The result is almost like when you get your teeth polished at the dentist. ;-)

In normal operation with a normal toothpaste, I see no difference to my otherwise preferred Deep Cleaning Brush. Therefore, and because the brush feels very hard, I think this brush for 2 x daily cleaning does not make sense. But for a "now and then" Complete Polishing they are ideally suited. Most importantly, they solve stubborn deposits.
The downside, and the reason why these brushes are not suitable for continuous use. They work very hard (through the yellow hard rubber plug in the middle), and the brushes are not very good to reach the potential in the gaps.

+++++ Made in Germany! (Compared to the new TriZone brushes, which are now no longer produced in Germany!)

PS. If you liked my review, or helped in the decision, I would be happy about an assessment very.
Only in this way can know whether the effort has paid off the reviewer. ;-)
