Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

In permanent human dentition, there are a total of 32 teeth. The distribution of these teeth in each jaw is as follows:

  • Incisors: 4
  • Canines: 2
  • Premolars: 4
  • Molars: 6

This results in a total of 16 teeth per jaw, or 8 teeth in each quarter of the mouth. While the primary (deciduous) dentition consists of 20 teeth, the permanent set replaces these and adds the adult molars, which erupt behind the primary teeth.12
