Q
  • 10 year old patient
  • unhappy with front teeth appearance
  • Sensitivity while brushing
  • Asthamtic
  • brushes twice daily with 1450ppm

When would you compensate an extraction of a permanent first molar?

A
  • when the upper 6 will by unopposed for a long time - to avoid over eruption
  • when there is a clear occlusal requirement ( not aligned teeth interfering with the occlusion)
