Time-lapse imaging of a developing tooth germ derived from a mouse embryo Tooth development or odontogenesis is the process in which teeth develop and grow into the mouth . Tooth development varies among species.
In animal tooth development, dentinogenesis is the formation of dentin, a substance that forms the majority of teeth. Dentinogenesis is performed by odontoblasts, which are a special type of biological cell on the outer wall of dental pulps, and it begins at the late bell stage of a tooth development. The different stages of dentin formation ...
Since many of the foods are abrasive enough to cause attrition, rabbit teeth grow continuously throughout life. [2] Rabbits have a dental formula of 2.0.3.3 1.0.2.2. There are no canines. Three to four millimeters of tooth is worn away by incisors every week, whereas the posterior teeth require a month to wear away the same amount. [3]
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name molar derives from Latin, molaris dens, meaning "millstone tooth", from mola, millstone and dens, tooth. Molars show a great deal of diversity in size and shape across the ...
New, permanent teeth grow in the jaws, usually under or just behind the old tooth, from stem cells in the dental lamina. [5] Young animals typically have a full set of teeth when they hatch; there is no tooth change in the egg. Within days, tooth replacement begins, usually in the back of the jaw continuing forward like a wave. On average a ...
In the inductive stage, the morphodifferentiation phase the shape of the crown is determined by the bell stage of tooth development. There is a basal lamina between the IEE and the dental papilla. [2] At this time, the dentin is not mineralized. The IEE cuboidal or low columnar with centralized nuclei and poorly developed Golgi complexes.

A toothcomb (also called a tooth comb or dental comb) is a dental structure found in some mammals, comprising a group of front teeth arranged in a manner that facilitates grooming, similar to a hair comb. The toothcomb occurs in lemuriform primates (which include lemurs and lorisoids), treeshrews, colugos, hyraxes, and some African antelopes.
