MICROANATOMY

Detailed explanation-1: -The primary teeth erupt during the first year and into the third years of life and are then exfoliated(shed) between the ages of 6 and 12. Since primary teeth are shed, as some trees shed their leaves, they are also referred to as deciduous teeth, which are eventually replaced by the adult permanent dentition.[2]

Detailed explanation-2: -Milk teeth are the first teeth babies get. These teeth start developing before a baby is born and will normally start to come through when an infant is between 6 and 12 months old. By the time a child reaches 3 years they can expect to have a full set of 20 milk teeth.
