How many canine teeth are there in adult human?

4

The correct answer is Option (2) -4

A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13:

• Incisors (8 total): The middlemost four teeth on the upper and lower jaws.

• Canines (4 total): The pointed teeth just outside the incisors.

• Premolars (8 total): Teeth between the canines and molars.

• Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food.

• Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
