Keep your smile at its best with these Braun Oral B Cross Action Replacement Brush Heads. Each pack includes 5 replacement heads featuring X-shaped bristles that lift trap and remove plaque effectively. The 2200 angled bristles are positioned at 16 degrees to clean efficiently along the gumline for superior plaque removal. You'll know exactly when it's time for a change thanks to the usage indicator - the bristles turn yellow when they need replacing. These heads are compatible with most Oral-B rechargeable handles (except Pulsonic Sonic Complete Vitality Sonic CrossAction Power Clic and Oral B IO). Model number: EB50RX5.
