Invisalign is a great form of treatment to close gaps between the teeth. Have a look at our website for an example by clicking on this link http://www.dental-suite.co.uk/blog/closing-a-gap-between-teeth-with-invisalign/
It is very difficult to say if your daughter is a suitable candidate for invisalign without knowing her age and what adult teeth are present. Furterhmore, it is very difficult to say what treatment option is the best suited for your daughter without a detailed clinical and radiographical examination. I would recommend a consultation with a dentist
Best of Luck
