Do you think i'll need tooth extraction for braces?

No clue: Without examination, it is impossible to tell. Only a fraction of orthodontic patients need extractions. As your orthodontist during your consultation.

If: If you have enough bone to support a full compliment of teeth, no extractions. If tooth size exceeds bone size, extractions may be necessary. Can't grow the size of the jaw bones in adults, only kids. See an Orthodontic Specialist for an opinion. They should be able to give you a pretty good idea at the very first visit as to what to expect.
