Question

How many teeth does the average human have?

Answer 1

Humans have teeth for crushing, biting, and grinding of food before it reaches the esophagus and the stomach. Human teeth are attached in a socket.

Complete answer:
1)The human teeth are classified into four types that are incisors, canines, premolars, and molars. All four types have different functions in humans.

2)Humans show two types of teeth in their lifetime that are milk teeth also known as primary teeth and deciduous teeth and permanent teeth also known as secondary teeth. The deciduous teeth are only 20 in number where 10 teeth are in the upper jaw maxilla and 10 teeth are located in the lower jaw mandible. These deciduous teeth are later replaced by permanent teeth, out of which 16 teeth are present in the upper jaw and the rest 16 are present in the lower jaw.

3)Humans are known as diphyodont due to their ability to develop two sets of teeth and the human teeth are also known as thecodont because they are inserted in the socket of the jaws.

Note: The third molars in humans are known as wisdom tooth but in rare cases, extra molars are observed. This condition is known as hyperdontia whereas a condition where less than 32 teeth are observed is known as hypodontia. Also, male teeth and female teeth show differences in teeth size as they are comparatively larger in males and the teeth enamel is more in the case of females.
