How is a sonic toothbrush different from a spinning one?

A sonic brush vibrates its bristles at high speed to move fluid around the teeth and gumline. A spinning brush scrubs with a rotating head. Both clean well; sonic suits people who find rotation too harsh.

Does it have a pressure sensor?

No pressure sensor is listed. You have to judge pressure yourself, so brush gently and let the bristles do the work.

It runs on a built-in rechargeable battery. Charging is done through the base or cable that comes with the brush, so keep that charger for top-ups.

Is it good for sensitive teeth and gums?

Sonic action is generally gentle, but this model lists no sensitive mode. If your gums bleed easily, start on the lowest setting you have and use a soft brush head.

What comes in the box?

Expect the brush handle, at least one brush head and the charging accessory. Check the box contents before you buy if you want spare heads included.

How does it compare with premium sonic brushes?

It covers the core sonic cleaning and rechargeable battery. Premium models add pressure sensors, multiple modes, timers and app coaching, which cost more and add complexity.
