Review on Philips Sonicare C3 Premium Plaque Defence HX9042 for sound brush, black, 2 pcs. by Agata Kozio ᠌

The nozzle has round bristles. Unlike the nozzles that come with a toothbrush, there are a lot of them. Due to this, the bristles cover a large surface of the teeth and clean them even better. Removes tartar and the enamel becomes lighter. The rubberized head is soft and does not cause discomfort when touching the teeth. There is also a bristle color indicator. The bristles themselves will tell you when you need to change the nozzle to a new one.
