About every six weeks during Invisalign treatment, patients visit the Sacramento dental office of Sacramento Dentistry Group to monitor their orthodontic progress. Patients see comparisons between their appearance now and during previous visits. Any dental work required to maintain progress is completed during these visits. Invisalign continues to send aligners every two weeks, making adjustments to a patient’s plan based on the dentist’s observations and recommendations. Always bring your aligners with you when you come to your appointments and the next set of aligners if you have already received them.
