Solution:

An adult human has 32 permanent teeth. The arrangement of teeth in each half of the upper and lower jaw is represented by the dental formula 2123/2123. This means that in each half of the jaw (upper or lower), there are:

  • 2 Incisors

  • 1 Canine

  • 2 Premolars

  • 3 Molars

Adding these numbers for one half of either the upper or lower jaw: 2 + 1 + 2 + 3 = 8 teeth.

Therefore, there are 8 teeth present in each half of the upper jaw and 8 teeth present in each half of the lower jaw.
