Every orthodontic case is unique, and there may be more than one correct solution. The best approach is to put your trust in a specialist who can convince you of the treatment plan they are proposing.
If you come across significant differences between the opinions of different orthodontists, it is well worth seeking further consultations. Taking out teeth is irreversible, so you should be given clear reasons why it is necessary.
Differing opinions may come down to the specialists' different approaches and experience. It is important to weigh up the pros and cons of each proposal, taking into account the scientific evidence and the latest developments in orthodontics.
This answer is for general information. Your own case needs an examination by an orthodontist.
