Wisdom teeth usually erupt between the ages of 17 to 25. It is the third molar of permanent teeth. There are 4 wisdom teeth, located at the ends of the upper and lower jaws. It is common to have one or more wisdom teeth missing. For some people, their wisdom teeth can normally erupt, while for some others, their wisdom teeth may not successfully erupt and may become impacted.
Cause of impacted wisdom teeth
Wisdom teeth often do not have enough room to erupt because modern human beings have a smaller jawbone. This causes wisdom teeth to grow slanted, horizontally, or even to be completely buried inside the jawbone.
