Hi. If you need Invisalign, you have to be doubly sure that you'll continue wearing your aligners even when the tooth movement is uncomfortable. The speed of aligner treatment depends on patient compliance.
Also complicated cases are better treated with traditional or self ligating braces.
Next Steps
Please consult an orthodontist, they'll tell you what's best for you.
Health Tips
Don't trust the self scanned, home scanned aligner companies. Better to get it done at a certified clinic.
