Dr. Zhang Liwen
Wisdom tooth growth is a normal physiological phenomenon, referring to the third molar located at the very back of the dental arch in the human oral cavity. It typically erupts between the ages of 16 and 25. However, when wisdom teeth emerge, there may be insufficient space due to reduced length, width, and density of the jawbone, leading to impaction or other complications. Therefore, to prevent such problems, early preventive extraction is recommended.
