If your dentist agrees that you’re suitable for Invisalign, you’ll begin with a consultation during which you’ll be able to see a 3D time-lapse image of your teeth before, during and after treatment. You’ll need to sit for dental impressions, which will be sent to a lab so that your bespoke Invisalign retainers can be made. Then you simply wear the retainers for the prescribed amount of time, changing them every few weeks until your treatment is complete.
