Wisdom teeth are the last teeth to erupt into the mouth generally in your late teens and early 20s. Unfortunately, because of their late eruption, as well as a number of other factors, there is often not enough room in the back of our mouths for the wisdom teeth to come in properly. Often this creates situations where the wisdom teeth only partially come through the gums or are angled in strange directions. This makes it very difficult to keep the wisdom teeth clean and often leads to inflammation and infections of the surrounding gum tissue, food impaction, cavities, and pain.
