your history seems you need orthognathic    surgery and orthodontic treatment for your jaws and teeth.....Get x_ray (cephalometry) of your skull and jaw bones done to rule out the problem...Treatment procedure os based on your X_ray diagnosis only....Jaw surgery cost starts from Rs.25,000..Bt it may vary depends on severity of problem

Hello mam, For you is surgery required or not, we need to decide based on some investigations like taking opg , lateral ceph and need a clinical examination also... You can find orthodontic speciality in almost all dental clinics.. Is surgery required or it can be done through orthodontic treatment itself, this decision can be taken only after investigation and diagnosis.
