Extractions/Wisdom Tooth Removal
Having a wisdom tooth is normal. Humans develop 12 molars in all, three in each of the four quadrants of the mouth: the upper right and left, and the lower right and left. The third molars are the last molars to erupt, and are what we refer to as the wisdom teeth. Problems arise when there is not enough space for the wisdom teeth to break through the gums and fully align themselves with the existing teeth, and also when they develop inside the bones in a position that would prevent them from emerging through the gums at all.
In cases like these, extraction of the wisdom tooth will be necessary to prevent further problems such as decay (of the wisdom tooth itself and/or the tooth next to it), infection and swelling of the gums around the tooth, and cyst formation. Wisdom teeth may need to be taken out for orthodontic purposes as well.
