Keep your Sonic and Sonic One toothbrush performing at its best with our replacement heads. Designed to deliver a gentle yet effective clean, they easily reach every corner of the mouth. Regularly replacing your toothbrush heads, recommended every three months, helps maintain peak performance and hygiene, ensuring your teeth stay healthy and clean. These electric toothbrush heads feature dentist-developed soft bristles that protect enamel and gums while ensuring plaque is removed more effectively than with a manual brush. They are compatible with the Original and Sonic One toothbrush, but not with the Sonic Pro Toothbrush. Product packaging may vary.
