Wisdom teeth are the last set of molars. Most people start to get their wisdom teeth when they are teenagers, though some teeth don’t come in until you are in your early twenties.
Wisdom teeth have a purpose. They are another set of molars, but more often than not they cause more problems than they are worth. Wisdom teeth can come in misaligned, facing any direction. They can even try to come in horizontally, growing into your other teeth. This can damage your nerves and even your jawbone.
