The wisdom teeth, also known as the third molars, are the last molars. Most people have four wisdom teeth, two in the upper and two in the lower jaw (one on each side). These teeth usually begin to erupt in late adolescence or early adulthood, usually between the ages of 17 and 25.

While some people have adequate space in their mouths for their wisdom teeth to come out without causing problems, many people experience complications due to lack of space or crowding. 

Common problems associated with wisdom teeth include:

• Pressure: during their dissection they can cause pain, swelling and possible damage to the adjacent teeth
• Crowding: movement of adjacent teeth, disturbing the existing dental alignment
• Pericoronitis: inflammation in the gums that builds up in the wisdom tooth area due to inadequate oral hygiene and retention of food and germs
• Cysts or tumors: In rare cases, cysts or tumors may develop around the impacted wisdom teeth, potentially causing damage to the jaw and adjacent teeth.

Because of these potential complications, many patients undergo extraction of one or more wisdom teeth. Removal of wisdom teeth is a common dental procedure performed by oral surgeons or dentists. Extraction is often recommended when there is a risk of discomfort, infection or other problems.

Regular dental exams and x-rays can help monitor the dissection of the wisdom teeth and determine if extraction is necessary. If you experience pain or discomfort around your wisdom teeth, it is essential to consult a dentist for evaluation.
