Philips sonicare HX7990 Mode D'emploi page 15

Problem
The bristles of my
brush head change
color.
Solution
Make sure you use the correct brush head
holder (see chapter 'General description').
Make sure the bristles point towards the UV
light bulb.
Exposure to UV light may cause bristles to
slightly change color over time.
