Little Teeth With a Big Job

Children usually grow 20 baby teeth, also called milk teeth or primary teeth. The first, often the lower front teeth, usually appear around six months, though timing varies widely. Most children have all 20 by about age three.

As adult teeth develop in the jaw, the roots of baby teeth dissolve, loosening them. Children usually lose their first tooth around age six, starting with the front teeth. Adults usually have 32 teeth, including wisdom teeth, which do not always appear.

Baby teeth matter for chewing, clear speech and holding space for adult teeth, so losing them too early can lead to crowding. In many countries the tooth fairy swaps lost teeth for coins, while Spanish-speaking children await Ratoncito Pérez, a little mouse who collects teeth.
