As Dr Chan mentioned, it all depends on the position of the wisdom teeth.
I would say for most cases, the wisdom teeth do not affect invisalign or other orthodontic treatments. Removal of the wisdom teeth before Invisalign treatment would be advised when:
1) Distalization of the molars are required - moving the second molars back into the space of the wisdom teeth
2) Uprighting of the second molars - if the wisdom tooth is causing the second molar to collapse or tilt sideways, removal would be required in order to upright and straighten the second molar
3) Impacted wisdom teeth resulting in food impaction and/or tooth decay
Your dentist or orthodontist would be able to advise you better after a clinical assessment and checking the status of your wisdom teeth on an X-Ray.
Hope this helps!
Warm regards,
