Will Invisalign fix problem canine tooth? Or best to have traditional braces? (Photo)

I currently am on Invisalign and concerned that with 6 trays left (and after lots of refinement trays later) Invisalign will not correct my stubborn canine tooth. Are there any other options which is not as time consuming to fix this? Othrodonists tells me that all is progressing well and yes each set of trays do fit as I keep them on 24/7. But again I don't realistically think Invisalign will correct this. Too soon to panic? And any other options and advice would be greatly appreciated!
