The wisdom teeth begin to erupt around when an individual reaches the end of their teenage years. However, there are often people for whom this is delayed quite a bit. Wisdom teeth are also called third molars since they are the last to emerge. More often than not, the gums may not have enough space to accommodate a new tooth, leading to the tooth emerging crooked or impacted. These can cause infection, pain, discomfort, swelling of the gums, and more, all of which can lead to more severe problems if left untreated.
