Do I need to get braces again to close the gap between my two front teeth or can I just go in and change my permanent retainer
I had my braces taken off about 9 years ago. I have the perminent wire retainers in the back line of my top and bottom teeth. I am noticing a gap forming between my two front teeth. Can I go in and change the retainer to bring them closer together again or will I have to wear braces again?
