How do you get invisalign replacement retainer?

To get an Invisalign replacement retainer, first contact your orthodontist or dental provider who originally provided your Invisalign treatment. They can assess your needs and determine if a new retainer is necessary. You may need to schedule an appointment for a fitting, during which they will take impressions or scans of your teeth to create a custom replacement retainer. Once the retainer is ready, you can pick it up from their office.
