Why do i need to pull teeth out before getting braces?

To create space: In some circumstances, due to the size of your teeth and the size of your jawbone(s), there's not enough room for the orthodontist to straighten your teeth and give you a harmoneous smile. For that reason, teeth are sometimes extracted.

Size issue: It's a tooth-size verses bone-size issue. If you have too much tooth material for the amount of bone material to support it, either jaw expansion (this is a finite process limited by your genetic pattern) or tooth material reduction is indicated. If your orthodontic specialist is recommending tooth extraction you must have significant crowding or severe jaw malrelationships.
