Wisdom teeth, also known as third molars, are the last teeth to appear in the mouth during young adulthood or later. These teeth can cause issues due to reasons such as lack of space, uneven growth, pressure on other teeth, infections, and more. In such cases, a dentist may recommend extracting or surgically removing these teeth. This can help relieve pain and infection, prevent dental and jaw misalignment, and avoid other problems such as headaches, earaches, and speech difficulties.
