These replacement heads are specially designed to fit perfectly on all models of the Oral-B iO series. Whether you have the iO 3, 4, 5, 6 series or the advanced models 7, 8, 9, and 10, these heads attach securely, allowing for the proper transmission of micro-vibrations for a deep and thorough cleaning of your teeth.

The round head follows the design recommended by professionals, surrounding each tooth individually. Its bristles are arranged in such a way as to reach deep into the interdental spaces and along the gum line, helping with plaque removal and improving oral hygiene compared to a regular manual toothbrush.

Made from materials that respect tooth enamel, these heads offer a balanced cleaning experience. The bristles have the appropriate hardness to clean effectively without injuring the gums, making them a reliable alternative solution for your daily oral care, keeping your smile bright.

To ensure the best possible hygiene, it is recommended to change the head every 3 months. Over time, the bristles lose their shape and their effectiveness decreases. Replacement is easy with a simple click on the toothbrush handle, ensuring that your device always operates at its maximum potential.
