Frequently Asked Questions How often should I replace my child’s toothbrush head? Dental professionals recommend replacing your toothbrush every three - four months, or earlier, if the bristles become spread out or frayed. When bristles are worn out, cleaning effectiveness decreases. What’s the difference between Stages Power and other Oral-B electric toothbrush heads? Different types of Oral-B electric toothbrush heads focus on slightly different types of cleaning. Stages Power toothbrush heads are ideal for the growing needs of kids. Ortho is designed to clean around braces. Power Tip cleans between teeth, and can be used to clean around other orthodontic appliances. The Dual Clean features one brush head that rotates and another that moves side-to-side. Sensitive toothbrush heads offer gentle, yet effective cleaning. 3DWhite features a dentist-inspired polishing cup to remove surface stains. Floss Action toothbrush heads have Micropulse Bristles that penetrate deep between teeth to sweep away plaque for a floss-like clean (does not replace flossing). TriZone bristles sweep side-to-side to power away plaque while allowing you to brush as you would with a manual toothbrush. Precision Clean is specially designed for precision cleaning and more plaque removal along the gum line than a regular manual toothbrush. CrossAction toothbrush heads have angled bristles to encompass each tooth for thoroughly clean teeth.
