Teeth Structure
 
We have two pairs of teeth in our lifetime: Primary Teeth and Permanent Teeth. The first tooth normally comes in between 6 and 10 months. By age 2 - 3 years children usually have 20 baby teeth. At about 6 years of age a child starts to get the first of four permanent molars. They come in behind the baby molars. By age 12-13 years the permanent teeth usually come up over. After 17 years of age,1-4 wisdom teeth normally come up. So, we have 28 –32 permanent teeth.
