Colgate 360 sonic gum health battery powered toothbrush
A sonic toothbrush vibrates its head, but gum health still depends on gentle coverage of every tooth surface and the gumline.
The short answer
A battery-powered sonic toothbrush cleans with a vibrating brush head, but gum health depends mainly on gentle coverage of every tooth surface and the gumline.

What is the direct answer?
What does this question mean?
The brush head uses bristles and mechanical vibration against plaque on enamel and near the gingival margin. Pressure and angle matter more than the label on the handle.
What can you do next?
Place bristles partly toward the gumline, use light pressure, and move systematically tooth by tooth. Replace a worn head and clean between teeth separately.
When should you seek dental care?
See a dentist for bleeding, persistent gum swelling, recession, loose teeth, or pain despite improved technique.
What should you ask the dentist?
Ask whether your brush pressure is appropriate and which interdental size fits each contact.
