About 150 youngsters from years 1 and 2 are recording teeth lost as part of a worldwide tooth tally involving 250 schools.

The children taking part will count the number of teeth they lose over the next three months, and these are then tallied online.

The project has been incorporated into classroom activities, including graphing, mathematical comparison, dental hygiene lessons and art classes, in which children drew their impressions of the tooth fairy.

Teacher Terry Daud said that 22 teeth were lost in the first two weeks.

``I've never seen so many children excited by the prospect of losing a tooth,'' he said. ``I had a boy in my class last week who had lost an eye tooth and had his mouth covered in blood.

``He wasn't upset. He was just excited that he could colour in another square on the class tooth tally graph!''

The school is also counting children who do not lose a tooth while the tally is being conducted.

``A worldwide project such as this has endless possibilities,'' Mr Daud said.

``I have had a teacher of a year 1 class in Michigan ask for a video conference between her class and mine. If we can get the time zones happening, it could be fun.''
