I dreamed of playing the flute too - and even started lessons - but I have an overbite and I couldn't make my lips do that strange little thing they have to do in which you extend your bottom lip and blow out over it to make the noise - so my flute teacher told me that it'd be a long and uphill struggle unless I got braces.
My teeth weren't buck or anything - just a basic little overbite- so braces weren't in the cards and neither was my learning to play the flute- but I've always loved that instrument.
