This has been a hotly contested debate in the orthodontic specialty for decades. The short answer is - it depends on the problems at hand. A thorough diagnosis by a skilled clinician can unlock the puzzle for each individual case. And there are usually more problems than an overbite. An overbite by itself certainly does not require extractions to correct. But there are other problems to consider such as the way the molars fit together, the overjet, the lip support by the teeth, and the amount of crowding. Contemporary orthodontists will often favor non-extraction as a rule, but know that there are still cases that will be best treated by extractions for cosmetic, functional, and stability reasons.
