Internet-connected toothbrush unveiled

Brush smarter. That's the message from the makers of what is billed as the world's first Internet-connected toothbrush.

Unveiled Sunday at a preview event for the Consumer Electronics Show, the device includes a sensor that detects how much tartar is being removed in a brushing.

It also records brushing activity, so users can maintain a consistent cleaning each time. The device conveys the information wirelessly to a smartphone app, a particularly useful aid for parents who want to monitor the teeth cleaning efforts of small children.

But, the app can tell users if they have missed hard-to-clean areas or are not getting while brushing.

Orders will be available this summer through from $99 to $200, depending on the model, and will include a free mobile app.
