Zub se sastoji pretežno od dentina sa šupljinom koja je izvana prekrivena caklinom. Zub ima karakterističan oblik i strukturu, zauzima određeni položaj u denticiji, građen je od posebnih tkiva, ima svoj nervni aparat, krv i limfne žile. Unutar zuba je labavo vezivno tkivo, prožeto živcima i krvnim sudovima (pulpa).

Normally, a person has from 28 to 32 teeth. There are milk and permanent teeth – temporary and permanent bite.

In the temporary bite there are 8 incisors, 4 canines and 8 molars – a total of 20 teeth. In children, they begin to erupt at the age of 3 months. In the period from 6 to 13 years, milk teeth are gradually replaced by permanent ones.

The permanent bite consists of 8 incisors, 4 canines, 8 premolars and 8-12 molars. In rare cases, there are additional, complementary teeth (both dairy and permanent). The absence of third molars, called “wisdom teeth” is the norm, and the third molars themselves are already considered an atavism by an increasing number of scientists, but this is currently a controversial issue.
