Rotating canine teeth. What is the best treatment and will Invisalign work? (Photo)

Invisalign can de-rotate teeth.  Your Case would have to be worked up fully to give you the best advice.  The information you provided is not sufficient to give you accurate advice.  After taking appropriate records, you can get a clin-check made to help you see what the possibilities are.  A clin-check is a 3-Dimensional animation of the movements necessary to help you achieve your desired outcome. You can get your case worked-up in a number of ways and then decide which treatment option seems best. It will also give you an estimated treatment time to do the treatment.  What needs to be established is if enough room can be created to help de-rotate the tooth or not.  That can only be seen when your whole mouth is evaluated. Hope that helps.  Good Luck!  

Actually that is your lateral incisor and it is easily turned with invisalign.  That, however, may not be the tooth to worry about. It is the round ones that  are harder to turn.
