Animal Tooth Development
Tooth development or odontogenesis is the process in which teeth develop and grow into the mouth. Tooth development varies among species. Tooth development in vertebrates Fish In fish, Hox gene expression regulates mechanisms for teeth, tooth initiation. However, sharks continuously produce new teeth throughout their lives via a drastically different mechanism. Shark teeth form from modified scale (zoology), scales near the tongue and move outward on the jaw in rows until they are eventually dislodged. Their scales, called dermal denticles, and teeth are homologous organs. Mammals Generally, tooth development in non-human mammals is similar to human tooth development. The variations usually lie in the morphology, Dentition#Dental formula, number, development timeline, and types of teeth. However, some mammals' teeth do develop differently than humans'. In mouse, mice, Wnt signaling pathway, WNT signals are required for the initiation of teeth, tooth development. Rodents' teet ...
