When do children get teeth?

Babies get two types of teeth: milk teeth or primary teeth and permanent teeth. It is usual that most children get their first milk teeth about six months after birth, while some may not get them until they reach the first year of life.
Teething lasts a period until the molars appear..which may reach two years, and until the appearance of large teeth in the back of the mouth, which usually come in 23-33 months. These teeth have wide and flat surfaces that help in grinding food properly.
