Eruption of teeth is a process in which teeth move through the jawbone and over lying mucosa to emerge in the oral cavity. Humans are diphyodonts which means we have 2 sets of teeth during our lifetime.

Upper central incisor 7-10 months
Upper lateral incisor 8-11 months
Lower lateral incisor 9-13 months
Upper first molar 13-17 months
Lower first molar 14-18 months
Upper canine 16-22 months
Lower canine 17-23 months
Lower 2nd molar 24-31 months
Upper 2nd molar 25-33 months
Eruption sequence of permanent dentition:
Lower first molar 6- 7 years
Upper first molar 6-7 years
Lower central incisor 6-7 years
Upper central incisor 7-8 years
Lower lateral incisor 8-9 years
