smile correction can be done by two types of treatment now a days either by fixed orthodontic treatment(braces), or by smile design i.e, by laminates,veneers,crowns & full mouth rehabs. so if you want to go for ceramic braces it can be done after evaluation of the case clinically and your doubt about the pain its very rare and very minimal after the treatment commences the only issue is that the patient has to maintain the oral hygiene very much on a regualr basis.
