Question

write short note on temporary and permanent teeth​

Answer 1

Answer:

Deciduous teeth – commonly known as baby teeth, milk teeth, temporary teeth,[1] and primary teeth – are the first set of teeth in the growth development of humans and other diphyodont 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.

Permanent teeth or adult teeth are the second set of teeth formed in diphyodont mammals. In humans and old world simians, there are thirty-two permanent teeth, consisting of six maxillary and six mandibular molars, four maxillary and four mandibular premolars, two maxillary and two mandibular canines, four maxillary and four mandibular incisors.

Answer 2

Answer:-

Temporary teeth are also known as baby, milk, deciduous or lacteal teeth. The term deciduous means ‘to fall off’. These teeth are the first sets of teeth and are twenty in number (10 in each jaw). These teeth start erupting since the age of six months and generally keep on erupting until three years of age. These teeth help in retaining space which is later occupied by permanent teeth.

Permanent teeth erupts just beneath the roots of milk teeth and when a deciduous tooth prepares itself to fall out, its root starts dissolving.  Permanent teeth are also known as adult or seconday teeth....
