It is quite common to have wisdom teeth removed anywhere from 15 to 30.
A 17-year-old typically has 28 teeth if they have all their permanent teeth, excluding wisdom teeth. Most people develop four wisdom teeth, which may or may not erupt. If the wisdom teeth are included and fully developed, the total can be 32 teeth. However, it's common for some individuals to have had wisdom teeth removed, resulting in 28 teeth.
Not necessarily. It is most common to have 4 wisdom teeth although some may not come through. Some can impact and have to be removed. Sometimes you can have extra wisdom teeth - the world record is 12! Or like me, you can be missing them - mostly one or two, but maybe 3 and 5% of the worlds population (including me) have none at all. So, you are likely to have them, but not guaranteed. :)
They have no obvious purpose.
Not necessarily. Teeth tend to become more crowed as we age, especially the lower front teeth. This happens in some people regardless of whether they have wisdom teeth or not. Therefore, removing the wisdom teeth, solely for the purpose of hoping to get naturally straighter teeth, won't work.
Jana and Jill had their wisdom teeth removed.
Yes, wisdom teeth or 3rd molars are the most commonly missing or deformed teeth.
The wisdom teeth.

The teeth that are referred to as "wisdom teeth" are teeth numbered, 1, 16, 17, and 32. They are located the furthest in the back of the mouth. However, do not get these confused with the molars. The wisdom teeth come in where the gums are located.
no they are wisdom teeth
No, just like you don't get your baby teeth back! You don't get your wisdom teeth back!
