Wisdom teeth often known as third molars are the last teeth to erupt. One usually gets them in their late teens or early twenties. However, even instances of eruption in late adulthood are common. If they erupt smoothly and without any interruption, then they can be proved as an asset. But the problem with third molars is that in case they do not erupt properly or are misaligned, they would need to be extracted. If they are poorly aligned, then they can damage the adjacent teeth.
