Invisalign crowded bottom teeth before and after
Clear aligners can straighten some crowded lower teeth with planned forces, but the result depends on space, roots, bite, gums, and wear time.
The short answer
Clear aligners can straighten some crowded lower teeth with planned forces, but the result depends on space, roots, bite, gums, and wear time. Crowding can reflect tooth size, arch width, tooth position, or jaw relationships. Planning uses an examination and records to decide on attachments, enamel reduction, elastics, or another appliance.

Wear each tray as directed, remove it for eating unless instructed otherwise, clean it and your teeth, and attend checks for tracking and bite changes.
When should unexpected crowding treatment changes be checked?
Contact the treating clinician if a tray will not seat, an attachment detaches, gums recede, or pain or bite changes unexpectedly.
What should you ask about correcting lower tooth crowding?
Ask how much crowding can be corrected while protecting roots and gum support, and how retention will maintain the result.
