The Oral-B iO Series combines powerful, yet gentle micro-vibrations with Oral-B's unique dental professional inspired round brush head for a Sensational Clean & Irresistible Brushing Experience. The Gentle Care Refill uses extra soft bristles with a specially-designed overlay of concave and convex bristle trim patterns that allow it to precisely adapt to the curvature of the tooth and gum line. The thinner outer bristles surround each tooth to enable gentle cleaning along the gumline, and gently adapt to the unqiue curvature of the tooth, ensuring consistent plaque removal from every surface. Oral-B is the #1 recommended toothbrush brand by dentists worldwide.
