Losing first tooth is a positive experience for kids

That's according to research at the University of Zurich.

The study also reveals that previous visits to the dentist's as well as parental background and level of education affect how children experience the loss of their first tooth.

Children generally lose their first baby tooth when they're about six years old.

Deciduous teeth, more commonly known as milk or baby teeth, come loose and eventually falls out, leaving a gap which is then permanently filled by its replacement tooth.

This gradual process is probably one of the first biological changes to their own bodies that children experience consciously. The emotions that accompany this milestone are extremely varied, ranging from joy at having finally joined the world of grown-ups to fear about the loss of a body part.
