I have been using Invisalign for the past 2 years and the most problematic issue has been moving my left canine tooth down. I have had about 4 refinements done in the past year all because this particular tooth won't move. My dentist has not suggested alternatives on how to move the tooth down, other than assuring me that Invisalign will do the work. I want to know if there are any other alternatives that can be used alongside using my Invisalign tray?
