TEETH/TOOTH DEVELOPMENT IN KIDS

Normally teeth develop from three  steps

1.Mineralization

2.Eruption

3.Exfoliation 

Mineralization of tooth starts in the crown and progresses towards the root . mineralization starts when the baby is in the womb , at around 4-6 months of intra uterine life 

Eruption starts at 6-7 months of age . eruption starts in the the center of mouth (incisors ) and spreads outwards

After the first tooth , rest of the eruption occurs at the rate of one tooth every month.Number of teeth in an infant is age in months minus 6 (10 month old infant will have 4 teeth)

Exfoliation begins at 6 years of age and continues through 12 year of age

By three years of age  kids will have  full set of milk teeth (20 in number)
