What is the child's first set of teeth called?

Explanation

The primary teeth (dentes decidui in Latin) is the first set of teeth for children and other mammals. These are later lost and replaced with permanent counterparts. A human being has 20 primary teeth and 32 permanent teeth. They serve different functions, amongst which chewing and biting. They also hugely influence a person's looks and ability to talk and sing. The enamel on teeth is the hardest substance in the human body.
