Milk Teeth Eruption And Shedding

It would be quite interesting to know that our teeth start to develop within our mother’s womb right after a few weeks of conception. Milk teeth also called deciduous teeth or famously known as primary teeth are the first set of teeth that erupt in our oral cavity within six months of birth. Lower front teeth are the first teeth to appear in the oral cavity six months after birth. Different milk teeth show variations in shape, function and shedding pattern. To know more fascinating facts about baby teeth and how to take care of it, let’s keep reading!

Humans have two sets of dentitions, primary or deciduous dentition and secondary or permanent (adult) dentition. Generally, we have about 20 primary teeth and 32 permanent teeth. The primary teeth gradually appear through the gums during the first two and a half years of life. The four front teeth—two upper and two lower teeth usually erupt first, beginning as early as six months after birth.

Most children develop a full set of primary teeth by the time they reach three years of age. The child’s jaws continue to grow, making space for the permanent (adult) teeth that are in the formative stage and begin to erupt at about age six years. Primary teeth begin to shed between ages six-seven years. This process continues until the child is about age 12 years old.


Children show different patterns of tooth eruption and shedding, but most of the kids show a specific sequence. We see the following types of teeth in the primary dentition ie: two sets of incisors, canines and molars in both upper and lower jaw respectively. Beginning from sixth month after birth, the primary dentition period lasts till about six to seven years of age.

The eruption sequence of primary teeth is as follows :
