Wisdom teeth usually erupt between 15 to 21 years old. But you don't necessarily have to wait for the wisdom tooth to come out. In fact, before you have your wisdom tooth removed or any sort of teeth removed, or any extensive dental work, and you have the intention of doing braces.
I would suggest you go see a dentist first to consult on the braces suitability. It's possible sometimes that we can extract the wisdom tooth or keep it as part of the braces treatment plan.
For example, if I know I'm going to extract the tooth, I may use it as a form of anchorage to help the other teeth to move faster before I pluck the wisdom tooth.
