Three brushing modes for daily oral care

The Waterpik Sensonic electric toothbrush offers Clean, Stain Removal and Gum Care modes so adults can personalise each session. A rechargeable lithium-ion battery powers the handle for up to four weeks per charge and the set includes a premium travel case, USB-C to USB-A cable and charging base.

Consistent sonic action across a full charge

The motor maintains steady brush-stroke speed throughout the four-week battery cycle rather than fading after a few days. A built-in two-minute timer pauses every 30 seconds to prompt quadrant changes and shuts off automatically when the cycle ends.

Ultra-quiet operation with low power draw

Ultra-quiet technology keeps noise minimal during the two-minute routine while the USB-C to USB-A cable draws 1.0 A at 5.0 V from laptops, power banks or wall adapters. The ergonomic non-slip handle weighs 0.422 kilograms and reminder bristles fade from green to yellow when a new head is needed.

Questions about this item

How loud is the Waterpik Sensonic when it runs for the full 2-minute brushing cycle?

The toothbrush uses ultra-quiet technology and pauses briefly every 30 seconds to prompt quadrant changes, then shuts off automatically after 2 minutes.

Does the USB-C to USB-A cable charge the brush directly from a laptop, or do I need a separate wall adapter?

The included cable is rated 5.0V DC, 1.0A and charges from a laptop or power bank; a USB-A wall adapter is required but not included.

Can I keep using my old brush heads with this model, or do I need the specific Sensonic Contour heads?

Only genuine Waterpik Sensonic Contour Brush Heads, model STWB-3WW-B, are compatible with this handle.
