Experience superior cleaning power with the Oral-B Cross Action Brush Head. Engineered with precisely angled bristles, this refill head surrounds each tooth to remove significantly more plaque than a manual toothbrush. It is ideal for daily use, ensuring comprehensive cleaning coverage across the entire mouth. Maintain optimal oral hygiene by replacing your brush head every three months or sooner if the indicator bristles have faded halfway. This brush head is compatible with most Oral-B rechargeable electric toothbrush handles.
