Wisdom teeth are the last teeth to erupt in your mouth between 16- 21 years of age. They grow at the very back of a person’s mouth. There are normally four wisdom teeth in total, with one in each of the last corners of the top and bottom gums.
Often, there is often no room for the wisdom teeth in a person’s mouth, as the adult teeth have already developed. This lack of space may cause wisdom teeth to come through at an angle, or getting stuck and not come through fully, hence becoming impacted.
