The unrestricted design of teeth is nearly the same across the vertebrates, although there is sizeable modulation in their shape and position. The teeth of mammals have deep roots, and this figure is also create in some fish, and in crocodilians. In most teleost fish, how, the teeth are spoken for to the outer outwardly of the bone, while in lizards they are attached to the inner come up of the jaw alongside one side. In cartilaginous fish, such as sharks, the teeth are joined by means of cold ligaments to the hoops of cartilage that form the jaw.

Children's tooth development begins while the baby is in the womb. Teething usually occurs between the ages of six and nine months. Children usually have their full set of 20 primary teeth (milk teeth, baby teeth or deciduous teeth) by the age of three years. At about the age of six years, the first permanent teeth erupt (push through the gum).
