Tooth development or odontogenesis is the complex process by which teeth form from embryonic cells, ... 10 round epithelial structures, each referred to as a bud ...
Tooth development is commonly divided into the following stages: the bud stage, the cap, the bell, and finally maturation. The staging of tooth development is an attempt to categorize changes that take place along a continuum; frequently it is difficult to decide what stage should be assigned to a particular developing tooth.

Tooth development begins at week 6 in utero, in the oral epithelium. The process is divided into three stages: Initiation; Morphogenesis and; Histogenesis [2]; At the end of week 7 i.u., localised proliferations of cells in the dental laminae form round and oval swellings known as tooth buds, which will eventually develop into mesenchymal cells and surround the enamel organ.
Bottom teeth of a seven-year-old, showing primary teeth (left), a lost primary tooth (middle), and a permanent tooth (right) Tooth eruption in humans is a process in tooth development in which the teeth enter the mouth and become visible.
The mesial view of this tooth considers the portion of the tooth visible from the side closest to where the middle line of the face would be.the mesial axis should be parallel to the midline. The mesial side of the maxillary central incisor shows the crown of the tooth as a triangle with the point at the incisal edge and the base at the cervix ...
The cap stage is the second stage of tooth development and occurs during the ninth or tenth week of prenatal development. Unequal proliferation of the tooth bud forms a three-dimensional cap shape. Overlying this cap structure is the ectomesenchyme , which is attached to the mesodermal tissue known as the dental papilla superiorly, and lies ...

There are 4 main stages of tooth development: Bud stage; Cap stage; Bell stage; Crown stage; The first sign of tooth development is known to be as early as the 6th week of intrauterine life. The oral epithelium begins to multiply and invaginates into ectomesenchyme cells, which gives rise to dental lamina. The dental lamina is the origin of the ...
