As one of Oral-B’s premium brush heads, ultra-thin Sensitive Clean brushes that are gentle on the gums are combined with normal brushes that are tough on plaque. Sensei Clean removes up to 100% more plaque and reduces gingivitis by 100% compared to a regular toothbrush. The unique combination of rounded and ultra-thin brushes makes Sensi Clean ideal for anyone with a sensitive mouth and anyone who is just looking for a good, gentle cleaning. Can be used with all Oral-B handles except Pulsonic & iO.
