In the primary tooth eruption timeline, primary teeth eruption starts with lower central incisors at the age of 6 years. Then, the upper central incisors and lateral incisors erupts followed by lower lateral incisors after a few weeks. After that, the upper 1st primary molars and lower 1st primary molar erupt followed by the upper and lower primary canine teeth. The lower and upper 2nd molar teeth are the last teeth that erupt in the primary dentition.
