Can some people have deciduous teeth?

The early teeth or baby teeth or milk teeth are deciduous teeth because they eventually fall out. All the children have 20 baby teeth - 10 on the top and 10 on the bottom.

But at about the age of six most children begin to lose their baby teeth, which are then replaced with adult teeth.

When a child grows to an adult then they have more teeth than their childhood, that is 32 teeth, which contains 8 incisors, 4 canines, 8 premolars, and 12 molars (including 4 wisdom teeth).
