the dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells.
additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth.
the dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts.
cementoblasts form the cementum of a tooth.
osteoblasts give rise to the alveolar bone around the roots of teeth.
fibroblasts develop the periodontal ligaments which connect teeth to the alveolar bone through cementum.
tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible.
current research indicates that the periodontal ligaments play an important role in tooth eruption.
primary teeth erupt into the mouth from around six months until two years of age.
these teeth are the only ones in the mouth until a person is about six years old.
at that time, the first permanent tooth erupts.
