SoseckNot a problem! My DOJ is the 7th of November.
Electrolass is could very well be. I know that the teeth that you have showing all need to be in a straight line, you can have missing teeth at the back. Your bottom teeth can be less than perfect but only if they cant be seen when you smile. There were some very pretty girls at my open day but they didn't get through (one can only assume) because, they either had crooked teeth or a 'tiger tooth' (random tooth at the side).
Couldn't resist the smiley...
I would say if you have all of that work done, make sure you tell your dentist that you are applying for Emirates and see if there is any additional things that need doing as you need to have a dental medical, which can be sooooo expensive. Then you can wait till you get through and get the call or just have it all done in advance.
