I have braces since 2011 and I'm getting them off in a few weeks time and I'm really looking forward to it but I noticed black triangles. I don't really mind them as I think my teeth look good anyway. Would this slow down my braces coming off or would my orthodontist still take them off? Would the gum grow back over them once the braces are off? I don't really think they look ugly but I just want them off. Thanks
