Stages of Tooth Development
There are different stages in the development of tooth. The staging of tooth development is an attempt to categorise changes that occur along a continuous path and usually it is hard to decide what stage we should assign to a specific development of tooth. These stages are used to help students to focus on the different events in odontogenesis and are based on the appearance of developing structures.
The tooth germ (tooth bud) is a collection of cells that finally form a tooth. It is divided into three parts: the dental follicle, the dental papilla and the enamel organ.
- Fibro Blasts develop the periodontal ligaments, which connect the teeth to thealveolar bone through cementum.
- Osteo Blasts gives the alveolar bone around the teeth roots.
2. The dental papilla contains cells that develop into odontoblasts that are dentin-forming cells.
3. The enamel organ is composed of inner and outer enamel epithelium, stratum intermedium and stellate reticulum.
During the stages of odontogenesis, many physiological processes occur. These physiological processes include initiation, proliferation, differentiation, maturation and morphogenesis. Many of these processes overlap and are continuous during the development of tooth. Generally speaking, there are 6 stages for tooth development:
Initiation Stage
Bud Stage
Cap Stage
Bell Stage
Apposition Stage
Maturation Stage (Crown Stage)

- The dental follicle gives rise to three necessary entities:
- Fibro Blasts develop the periodontal ligaments, which connect the teeth to thealveolar bone through cementum.
- Osteo Blasts gives the alveolar bone around the teeth roots.
