What are the blue particles you can see in ProphyCare HAp?

The paste consists of silica particles of different sizes. We have chosen to colour some of the largest particles blue – so that the user can see how large the largest particles are, and to make it easier for us to explain how the paste works. It also adds a nice colour. Sometimes some of the coloured particles are left in the mouth after the first rinse, but they are completely harmless to the patient.
