Brush your teeth every day， dentists say. In the south of Africa， some people brush their teeth all day long.
They keep a small stick in their mouth to chew or scrub (洗刷） their teeth all day. People cut the sticks from trees. They are the African toothbrushes. People there are used to brushing their teeth with sticks.
Africans think the sticks work better than toothbrushes. The sticks come from nature， and it is said that there is something special about them. The special thing may stop many kinds of tooth problems. “If you have a bad tooth， it is a medicine，” said Diop， a seller in Africa.

How fit are your teeth? Are you lazy about brushing them? We brush our teeth every day but few people know how well we're brushing. Today, a French company has introduced an electric toothbrush, which can work wirelessly（无线地）with a smartphone. It's called the Kolibree toothbrush. It has different models, and will cost from$99 to$200 .The US is the first target market.
Users download an app and connect via Bluetooth, and the Kolibree will record: 1 .the time you spent brushing teeth. 2.whether all areas of your mouth are reached.
3 .whether you brush up and down instead of just side to side. Then it will send the information to a mobile phone via Bluetooth, telling you whether you have brushed in a proper way. The Kolibree records your progress and scores your brushing way to help you improve brushing habits. It's kind of like having a private dentist actually watch your brushing on a day-to-day basis.
The toothbrush can also talk to other apps on your phone, so developers could create a game controlled by your toothbrush. When you brush your teeth, you can score your points for beating the monsters in your teeth. That's really very interesting. The Kolibree toothbrush is created to be smart but also fun.
The Kolibree toothbrush was invented by Thomas Serval. He says the idea of inventing it came from his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They always answered "yes", but Thomas used to find their toothbrush heads dry. He decided that a kind of brush was needed to tell him how well they brushed their teeth.
Thomas says that one day, it'll be possible to use a brushing unit with a camera. The camera can even examine holes in your teeth while you brush.
