Invisalign before and after worst cases

More difficult cases can involve severe crowding, rotations, large gaps, an impacted tooth, a crossbite, or a mismatch between the jaws. Some need attachments, elastics, enamel reduction, extractions, or a fixed brace, and jaw discrepancies may require surgical assessment.

Have a clinical examination, photographs, radiographs when indicated, and a digital scan. The orthodontist evaluates the roots, periodontal tissues, jaw relationship, and space before explaining which movements are realistic; wear each tray as instructed and attend progress reviews.

Seek orthodontic care if a tray will not seat, a tooth becomes unusually mobile, the gums recede, or pain is severe or persistent. Urgent assessment is needed for facial swelling, trauma, or trouble breathing or swallowing.

Ask which part of the correction is difficult, whether attachments or elastics are needed, what happens if tracking is lost, and how retention will maintain the result.
