How many permenent teeths in humans?

The total number of permanent teeth in humans is 32. These teeth typically start to erupt between the ages of 6 and 21, replacing the primary (baby) teeth. The 32 permanent teeth are distributed as follows:

- Incisors (front teeth): 8 (4 upper, 4 lower)

- Canines (cuspid teeth): 4 (2 upper, 2 lower)

- Premolars (bicuspids): 8 (4 upper, 4 lower)

- Molars (back teeth): 12 (6 upper, 6 lower)

It's worth noting that some people may have an extra tooth called a "wisdom tooth" or third molar. Wisdom teeth are located at the back of the mouth and usually erupt in the late teens or early twenties. However, not everyone develops wisdom teeth, and some people may have only one or two instead of the typical four.
