D. 16

Show Answer…
Correct Answer: A (20)


The correct answer is A – 20 milk teeth. Human beings usually have a set of 20 primary or milk teeth during their early childhood.

Number of Milk Teeth in Humans

As babies grow and develop, so do their teeth. Among the various stages of dental development, the phase of milk teeth plays a crucial role in a child’s early years. Milk teeth, also known as primary teeth, baby teeth, or deciduous teeth, are the initial set of teeth that human beings have.

Understanding Milk Teeth

A typical human being usually possesses a total of 20 milk teeth. These teeth start to appear in infancy, usually around six months of age. Over the next few years, these tiny teeth help children chew and speak, playing a vital role in their growth and development.

The set of milk teeth consists of the following teeth types:

  • Incisors: These are the front teeth, four on the upper jaw and four on the lower jaw. They are used for biting and cutting food.

  • Canines: Positioned next to the incisors, these pointed teeth help tear food.

  • Molars: The molars are located at the back of the mouth. They have a flatter surface for grinding food.

Shedding and Transition to Permanent Teeth

As children grow, their jaw and facial structure change, necessitating a transition from milk teeth to permanent teeth. Starting around the age of six, the roots of milk teeth gradually dissolve, leading to the teeth becoming loose. Over time, the milk teeth fall out, making way for the emergence of permanent teeth.

By the time a child reaches their early teenage years, most of their milk teeth have been replaced by permanent teeth. Permanent teeth total 32 in number, which includes incisors, canines, premolars, and molars.

Caring for Milk Teeth

Even though milk teeth are temporary, they play a significant role in a child’s oral health and overall development. Proper care of milk teeth is essential to ensure healthy dental hygiene. Regular brushing, flossing, and visits to the dentist can contribute to maintaining healthy teeth and gums.


Milk teeth are an essential part of human dental development. These initial 20 teeth provide children with the ability to chew, speak, and interact with the world around them. As they grow, these teeth make way for permanent teeth, completing a natural cycle that marks different stages of human development.

Understanding the significance of milk teeth and ensuring their proper care lays the foundation for a lifetime of good oral hygiene. As young individuals transition from their milk teeth to permanent teeth, they embark on a journey toward maintaining healthy smiles and overall well-being.
