Teeth malformation

Tooth development or odontogenesis is the complex process by which teeth grow, and erupt into the mouth. Primary (baby) teeth must start to form between the sixth and eighth weeks, and permanent teeth begin to form in the twentieth week. If teeth do not start to develop at or near these times, they will not develop at all.

There are a number of tooth abnormalities relating to development that may be acquired and inherited ones that alter the size, shape and number of teeth.

The basic types of malocclusion are crowding, protruding upper incisors and prominent lower jaw. Though there can be a number of other teeth abnormalities that occur not very often such as anodontia - a complete lack of tooth development, and hypodontia - a lack of some tooth development, supernumerary teeth – an extra one tooth to the normal complement of 32 teeth, missing teeth - upper incisors are often missing.
