Elevate your daily routine with the Oral-B iO Ultimate Clean Replacement Brush Heads, a pack of two designed to deliver a professional clean at home. Engineered exclusively for the Oral-B iO Series, these white heads feature pioneering bristle technology for superior plaque removal and gum care. The unique tuft-in-tuft design combines longer inner bristles to reach deep between teeth with shorter outer bristles for a comprehensive surface clean. Each tuft is made with twisted bristles that adapt to the unique contours of your teeth, while the classic round head surrounds each tooth to effectively disrupt plaque biofilm. The bristles are precisely angled to target the gumline, helping to reduce inflammation. An integrated colour-changing indicator fades to signal when it's time for a replacement, ensuring optimal cleaning performance every time. Clinically proven to remove up to 100% more plaque along the gumline than a regular manual toothbrush, these heads provide a gentler yet exceptionally powerful clean. For best results and continued oral health, replace your brush head every three months. Simply align the head with your iO handle, press firmly until it clicks, and enjoy a refreshed, professionally polished feeling. Rinse after use and allow to air dry. Please note: this product is intended for adult use. Supervise children and check for wear before each use.
