Best Invisalign doctor near me Fewer Consultations Required With Invisalign, much of the orthodontist’s work happens before you wear your aligners. A 3D scan of your teeth is used for making all the customised retainers in a laboratory. You should change the multiple sets of retainers on your orthodontist’s directions. There is no need to visit the orthodontics for adjustments so visits are kept to a minimum to check on progress. Few visits to the orthodontist means less time off work.
