Answer 1

The child will aged between 6 to 12 years

Step-by-step explanation:

The permanent teeth erupt according to the developmental stages of a child.

Permanent teeth like the molars begin to erupt in children when they are six years old. The permanent molars are of three types according to the order of their eruption – first, second and third molars.

The first permanent molars begin at the age of six and also called the six-year molars. The second permanent molar erupts by 11 to 13 years. The third set compromising the wisdom teeth arises between 17 to 21 years of age.

The childhood period ranges from 3 to 12 years. Since the eruption of permanent molars has begun, the child must be aged between 6 to 12 years where both first and second permanent molars will erupt.
