My bottom teeth is slightly crooked. I want to use braces for both my upper & lower teeth for perfect teeth. Am I too old for it? BTW, I'm located in Philippines. How long would you think I'll use braces? Actually, I'm turning 15 this August & by Aug. 2012 I want my braces to be removed. I don't want to use the invisible or behind the teeth braces. Just the Traditional Metal braces. HELPP!! :)
