Hi no matter the size of the teeth if they are too much out of arch form or are crowded in a tight space you may need need braces. Braces are now possible in grown adults as well. Minor corrections are dealt with prosthetic crowns or veneers. We specialize in both at Care dental in Thane. Usually cost for stainless steel braces is 30000 rs and for ceramic braces which are more esthetic is 40000. All the best.
