What is a "wisdom tooth"?

A wisdom tooth refers to the third molar that emerges at the back of the mouth during young adulthood. These teeth are the last to erupt, usually between the ages of 17 and 25. Wisdom teeth can vary in their eruption patterns and may sometimes be impacted, meaning they do not fully emerge due to lack of space or obstruction. Impacted wisdom teeth can lead to discomfort, infections, and other dental issues, often requiring extraction. Not everyone develops wisdom teeth, and their presence and management depend on individual factors and dental evaluations.
