Oral-B iO Ultimate Clean Original Replacement Heads, Black, Pack of 4

Oral-B Series iO Ultimate Clean Refill Heads combine powerful yet gentle micro-vibrations with our unique dentist-inspired round head design to bring you a professional clean feeling every day. Designed exclusively for Oral-B iO electric toothbrush handles, the Ultimate Clean toothbrush heads help remove up to 100% more plaque than a regular manual toothbrush for clean, shiny teeth. With a precise 16 degree angle, the slanted filaments help clean hard-to-reach areas of the mouth. Since dentists recommend changing your toothbrush head every 3 months for best results, Oral-B replacement heads feature filaments that fade to white to indicate when it's time to change it. Enjoy superior cleaning power with the unique replacement heads uniquely designed to fit your Oral-B iOS electric toothbrush perfectly. Directions For deep cleaning, replace the head when the bristles change color. The original Oral-B replacement brush head is designed for deep cleaning, the only one compatible with your Oral-B iOS electric toothbrush. To effectively and smoothly remove up to 100% more plate along the gincival edge, use the angled replacement head. Replace your head every 3 months to ensure effective cleaning. Safety Warning Replace the brush as the threads fade to optimize your brushing. For superior brushing, replace the brush every 3 months.
