Osmosis video - Development of the teeth

Human teeth development starts at around week 6 of gestation. Teeth development occurs in several stages. There is the bud stage, during which dental placodes develop into bud-like structures, known as the tooth buds, attached to the oral epithelium by the dental lamina.

Next is the cap stage, characterized by the growth and expansion of the enamel and the formation of a concavity in its inner aspect. Then comes the bell stage, during which the primitive tooth epithelium forms the bell-shaped structure, which later becomes the tooth crown. This is followed by the later-bell stage, during which teeth start to differentiate their crowns morphologically into what will later become all kinds of teeth that we know, such as incisive, canine, premolar, and molar.
