There is no one-size-fits-all answer to this question.
Wisdom teeth sit at the very back of the dental arch, and the space they free up is often too far from the area that needs it. If there is a significant lack of space for the front teeth, removing only the wisdom teeth is sometimes not enough, and premolars may need to be removed as well.
If the problem can be solved by removing only the wisdom teeth, that is the better option. Orthodontics has many techniques and tools that make it possible to achieve almost any tooth movement.
This answer is for general information. Your own case needs an examination by an orthodontist.
