Should my orthodontist charge me for Invisalign refinements?

Sorry to hear that you need a refinement, but this is pretty common with clear aligners.  Since you're not sure whether your dentist told you that refinements would be free or not, you would have to go with what you remember and believe that he/she is being truthful with you now.  Generally speaking, it depends on your specific case.  If you were in an express or limited case, then you will likely have to pay for refinements.  If you are in a complete case, then a certain number of refinements would be of no charge.  If your doctor is charging you for refinements, it is likely you had a discounted treatment plan to begin with and these are additional charges incurred.  Good luck and I hope this helps.

Every office has their own policy. It does take the staff time and materials to order a refinement. But in my office all refinements and corrections are included. 

Did you sign a contract? if so, it should state what is included in treatmentRefinements should not be an additional charge unless the reason the treatment is not on track is because you have not worn the appliances as instructed!
