How Long Does Invisalign Take?

A realistic guide to the Invisalign timeline

How long Invisalign treatment usually takes, what the journey looks like, and how to keep your treatment on track.

If you are thinking about clear aligners, you probably want to know how long Invisalign takes before you start. While every smile is different, here is a realistic guide to the Invisalign timeline at Harmoni Dental in Kingston.

Typical Invisalign treatment time

Most patients complete Invisalign treatment in 6 to 18 months. Simple cases, such as minor crowding or a small gap at the front, can finish in as little as 3 to 6 months with Invisalign Express. More complex cases that move many teeth take longer.

What the journey looks like

  • Consultation and digital scan, with a 3D preview of your result
  • Wearing your aligners 20 to 22 hours a day, removing them only to eat and clean your teeth
  • Changing to a new set every 1 to 2 weeks
  • Short progress reviews every 6 to 8 weeks
  • Retainers at the end to keep your new smile in place

How to keep treatment on track

The single biggest factor in finishing on time is wearing your aligners for the recommended hours each day. The more consistent you are, the smoother and faster your treatment. For the full picture, see our guide to Invisalign in Kingston.
