  • the neck, point of union between the crown and the root
  • the root, an invisible part anchored in the alveolar bone and covered by the gum, which is made up of cementum, dentin and pulp canal

From 6 years old and up to about 12 years old, the temporary teeth fall out and give way to the permanent teeth, which correspond to the second dentition. The last dentition corresponds to the growth of wisdom teeth around 18 years old. In the end, the permanent dentition includes 32 teeth. (2)
