Yes, Invisalign can correct tooth crowding. Many things, including the initial loss of baby teeth, unusually shaped teeth, and a gap in the lip or palate, may result in overcrowded teeth. By continuously exerting mild pressure to aid optimal alignment, Invisalign may strive to correct these problems.
Overcrowded teeth may need further care, such as extracting any problematic teeth. By shifting every tooth up by 0.2mm for each new aligner, Invisalign may help straighten crowded teeth, giving you more space in the mouth once the teeth are correctly positioned.
