As wisdom teeth are the last permanent teeth to come in, or erupt, there is often not enough room left in your mouth to accommodate them.
Wisdom teeth are the third and last molars on each side of the upper and lower jaws. They are also the final teeth to erupt; they usually come in when a person is in their late teens or early twenties.
Wisdom teeth that only partially emerge or come in crooked can also lead to painful crowding and disease. As teeth removed before age 20 have less developed roots and fewer complications.
