Experience a superior cleanse that’s gentle on sensitive mouths with the Oral-B Sensi UltraThin CleanPower Replacement Brush Heads; a set of four dentist-designed toothbrush heads that are compatible with the entire line-up of Oral-B rechargeable electric handles.* Specially engineered to clean tooth by tooth through surrounding and swivelling action that dislodges food and plaque build-up, the professional-grade brush heads are fitted with a petal-shaped combination of soft, fine bristles that are gentle on sensitive gums and regular bristles that are tough on plaque. Indicator bristles fade over time to show when it’s time to replace (dentists recommending replacing your toothbrush every 3-4 months). In comparison to a manual toothbrush, the brush heads remove up to 100% more plaque and reduce gum inflammation by 100%. *Compatible with all Oral-B rechargeable electric toothbrush handles, except for Oral-B sonic toothbrushes.
