How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track(监测) your performance on your phone.

The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

The toothbrush will be able to teach you to brush in a right way and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing.” says Thomas Serval, the French inventor.

The toothbrush will also be able to talk to other apps on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.

Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

The company says the Kolibree will go on sale this summer, from $99 to $199, depending on features.

Serval says that one day, it’ll be possible to replace(代替) the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.
