What is Wisdom Tooth?
Wisdom teeth are the last molar on each side of the jaws. They are also the last teeth to emerge when a person is between age 16 and 20. Since it is the last permanent teeth to come in, there is often not enough space left in the mouth to accommodate them. This can lead to wisdom teeth impaction, trapped beneath in the gum tissue by other teeth or bone. If they are impacted, tenderness and swelling may occur. Wisdom tooth that partially emerge or come in crooked can lead to painful crowding and disease. Therefore surgery to extract the wisdom tooth is necessary if such symptom happen.
