Oral-B Pro Cross Action Toothbrush Heads are engineered for a superior clean, reaching deep between teeth and along the gumline to remove up to 100% more plaque than a regular manual toothbrush. Featuring unique criss-cross bristles, these replacement heads oscillate, rotate, and pulsate to break up and sweep away plaque effectively. They are designed to ensure you maintain optimal cleaning performance by replacing your brush head every three months, or sooner if the indicator bristles have faded halfway. Ideal for daily comprehensive oral care, these heads offer reliability and professional-level cleaning right at home.
