HUMAN TOOTH DEVELOPMENT - Vivek Gupta - Bog

Tooth development or odontogenesis is the complex process by which teeth formed from embryonic cells grow, and erupt into the mouth. For human teeth to have a healthy oral environment, all parts of the tooth must develop during appropriate stages of fetal development. Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week.
