Wondering how quickly Invisalign can straighten your teeth? The honest answer depends on your specific case — but most adults complete treatment in 12–18 months.
Several factors influence your timeline: the severity of crowding or spacing, how consistently you wear your aligners (20–22 hours daily is required), and whether you need any refinements mid-treatment. Mild cases can finish in as little as 6 months. More complex cases with significant bite correction can extend to 24 months. The single biggest variable within your control is compliance — patients who wear their aligners as prescribed consistently finish faster and with better results. At Sonrisa, we use the iTero scanner to run a ClinCheck simulation before treatment begins, so you can see your projected finish date before committing to a plan.
