Common Questions
Is an electric toothbrush really better than manual?
Yes — clinical studies consistently show electric toothbrushes remove 21% more plaque and reduce gingivitis 11% more than manual brushing. The oscillating/pulsating action is more effective.
Oral-B vs Philips Sonicare — which is better?
Oral-B's oscillating-rotating action is slightly more effective at plaque removal; Sonicare's sonic vibration feels gentler and is preferred by people with sensitive gums.
How often should I replace the brush head?
Every 3 months, or when the indicator bristles fade to white — worn bristles are significantly less effective at cleaning along the gumline.
Can kids use electric toothbrushes?
Yes — children's electric toothbrushes (Oral-B Kids, Sonicare for Kids) have softer bristles and smaller heads, and kids brush longer when using a fun, timed device.
