Hi, I'm in braces for the second time too. Not wearing my retainer and my wisdomw teeth coming thru has meant 3 years after getting my braces off i'm back in them for a second time as an adult. 3-4years in full braces, 4 elastic bands will be fitted soon which i'm told i will have to wear for the rest of my treatment. I wasnt too happy when i was told but now after a month back in them its not so bad.
