Well I didnt get my top ones taken off due to a gap not yet closed ...by about half a millimetre
but i did ask my ortho about this, and he said that my teeth should settle ok, apparently teeth have a forward movement anyway, and this gap (about 1mm) should close in time..
and apparently I am getting a hawley for when I graduate to night time wear in 3 months, I guess something can also be done if things havent righted themselves by then...
