Why is wisdom tooth bad?
Wisdom teeth are not necessarily bad. They do, however, frequently cause crowding in the mouth, forcing the molars forward resulting in crooked teeth. They can also become impacted or fail to fully erupt (emerge through the gums), causing discomfort and potential for decay or gum disease. Dentists often recommend removal of wisdom teeth
in younger people if problems are foreseen; if you make it through your twenties with no troubles, you'll most likely be fine. If you have any issues with any of your wisdom teeth, most dentists will recommend removal of all four, as asymmetry in the mouth can result in other problems. By all accounts, extraction of the wisdom teeth kind of sucks.
