What Is A Wisdom Tooth?
“Age of Wisdom”
Wisdom teeth, also known as third molars, are the last teeth to erupt in your mouth. This generally occurs between the ages of 17 and 25, a time of life that has been called the “Age of Wisdom.”
Anthropologists note that the rough diet of early humans resulted in the excessive wear of their teeth. Normal drifting of the teeth to compensate for this wear ensured that space was available for most wisdom teeth to erupt by adolescence. The modern diet, which is much softer and the popularity of orthodontic tooth straightening procedures produce a fuller dental arch, which quite commonly doesn’t leave room for the wisdom teeth to erupt, thereby setting the stage for problems when the final four molars enter the mouth.
Complications from Impacted and Partially Impacted Wisdom Teeth
Complications may arise from partially impacted teeth (fig. a and b) and totally impacted tooth (fig. c).
Wisdom teeth growth by age
Wisdom teeth are easier to remove when the patient is younger. since their roots are not completely formed, the surrounding bone is softer, and there is less chance of damaging nearby nerves or other structures.
Removal of wisdom teeth at a later age becomes more complicated as the roots have fully developed (may involve the nerve), and the jawbone is denser.
