Tooth development starts between the 3rd and 6th months of pregnancy,
The growth of baby teeth is only completed at the age of 4, when the roots of all the erupted teeth are fully formed. The crown of the tooth is the first to develop deep in the jawbone. The root formation will only be completed about 18 months after eruption. When the crown of a tooth erupts it is covered by a cuticle or covering that protects the enamel.It is slowly worn away by chewing and tooth brushing.
