B. 12
C. 6
D. 4

Answer 1

Hint: Canines are used to tear food and occur behind incisors. The sharp, pointed teeth are canine, lying next to the incisors, almost like fangs. Dentists also call them eyelashes or cuspids.

Complete solution:
Children are not born with teeth. It usually starts erupting from 10 months of age and finishes around 29 months of age.
Children consist of 20 teeth which are also known as baby teeth, milk teeth or eye teeth.
Baby teeth consist of incisors (cutting teeth), canines (tearing teeth) and molars (grinding teeth).
Out of 20 teeth, 4 are canines which is also known as cuspid, 8 are molars and 8 are incisors.

So, the correct answer is D. 4

The tooth consists of a crown and root.
Tooth helps in breaking down solid food into simpler components.
Permanent teeth of humans consist of 32 teeth.
Human teeth are made up of – pulp, dentin, enamel and cementum.
The eruption of permanent teeth causes root resorption causing the roots to be dissolved by odontoblasts.

Note:
Sharp canine teeth are a characteristic feature of carnivorous animals who require it for tearing their food along with sharp claws.
The process of replacement of baby teeth by permanent teeth is known as exfoliation.
From the age of 12, there are only permanent teeth. However, some baby teeth also retain beyond this age if the secondary teeth fail to develop in time.
The muscles of the jaw and the formation of jaw bones depend on primary teeth as primary teeth help in maintaining proper spacing for permanent teeth.
