Answer 1

Answer:

As humans, we have two sets of teeth that erupt during our lifetime – the first set is called as milk teeth, primary teeth or baby teeth and they start erupting when we are 6 months old and the next set of teeth, called permanent teeth, begin erupting as we turn 6 years old.

Answer 2

Why do we have two types of teeth - milk teeth and permanent teeth?

Answer:

The next difference between primary and permanent teeth is that the enamel layer on the primary teeth is much thinner than that in permanent teeth. This difference between deciduous and permanent teeth is important because thinner enamel allows cavities to spread quickly.
