Philips Sonicare C2 Optimal Plaque Defence HX9022/10 for sound brush, white, 2 pcs. Review

Thick, high quality bristles remove up to 7 times more plaque than a regular toothbrush. The special curved tip makes it easy to clean the back teeth. The Philips Sonicare C2 Optimal Plaque Defense brush head syncs with the Philips Sonicare BrushSync handle to select the optimal mode and intensity for a flawless brush. Brush heads will become less effective after 3 months of use, but with BrushSync you''ll get a reminder before that. The smart toothbrush tracks frequency and intensity of use, so you''ll be notified when it''s time to replace.
