Did my orthodondist made a mistake? (photos)

Extracting teeth for orthodontics is common
Whether doing Invisalign or brackets and wires (braces), removing teeth to make room is common. It doesn't happen as often as in the past, but still happens (some dentists and orthodontists feel very passionately about removing teeth, so you may get a variety of opinions).
Yes, the goal will be to close the spaces after the teeth are removed, however from the photos it does not appear to be significant crowding. It may be possible to treat the case without the extractions.
I don't think so this would meant to happen but also I am not totally familiar with your case. But still you can visit any other dentist regarding this.
