What Are Wisdom Teeth?
The third molars and why they often cause problems
Wisdom teeth—the third molars at the back of each arch—are the last teeth to develop, typically emerging between ages 17 and 25. For many patients, there is not enough room in the jaw for these teeth to erupt fully and in proper alignment.
When a wisdom tooth cannot emerge normally, it becomes impacted—partially or fully trapped beneath gum tissue or bone. Impacted wisdom teeth can cause pain, swelling, infection, damage to neighboring teeth, and cyst formation. Even wisdom teeth that emerge partially are difficult to clean and prone to decay and gum infection.
