Please tell me if i should get my four teeth extracted to have braces on?

I can't: I cannot recommend extraction or non-extraction treatment without examining you. See a qualified orthodontic specialist for diagnosis and treatment planning. Follow his/her advice. 30% of orthodontic patients require the removal of 1 or more permanent teeth.

See an orthodontist: No one can answer that question without a complete examination including a panoramic radiograph and cephalometric radiograph. Even then there will be disagreement between doctors. Go with the doctor who has the most understanding of the scientific research. Do not use charisma as a criteria.
