INSIGHT

Clear Aligners Still Lead To Many White Spot Lesions

  • Clear aligners still cause a high rate of white spot lesions in adolescents during treatment.
  • A 2024 study found 35% of adolescent Invisalign patients developed WSLs, only modestly lower than ~45.8% with fixed braces.

Front Teeth Attachments Raise White Spot Risk

  • Anterior attachments increase WSL risk more than posterior ones.
  • The number of composite attachments on front teeth correlated with higher incidence and size of white spot lesions in the study.

Aligners Create A Greenhouse Effect That Favors Demineralization

  • Wearing aligners can trap food and reduce natural saliva cleaning, creating a greenhouse-like humid environment for bacteria.
  • Covering teeth after eating and long wear time (including night) favors rapid demineralization and biofilm shifts.
