Deciduous teeth
Deciduous teeth, otherwise known as milk teeth, baby teeth, temporary teeth, primary teeth are the first set of teeth in the growth development of humans and many other mammals. They develop during the embryonic stage of development and erupt — that is, they become visible in the mouth — during infancy. They are usually lost and replaced by permanent teeth, but in the absence of permanent replacements, they can remain functional for many years. Deciduous teeth start to form during the embryo phase of pregnancy. The development of deciduous teeth starts at the sixth week of development as the dental lamina. This process starts at the midline and then spreads back into the posterior region. By the time the embryo is eight weeks old, there are ten areas on the upper and lower arches that will eventually become the deciduous dentition. These teeth will continue to form until they erupt in the mouth.
