My last refinement trays (2nd time) only have slots for 3 buttons, and I have 20. The assistant was told to only add new ones, and not feeling comfortable to remove existing ones. My previous refinement didn't remove any. Did they send in the wrong order, forgot about my existing buttons, or the dentist wasn't clear about the instructions? The trays won't fit with my 20 buttons, and my dentist isn't reachable. Should I ask them to remove my existing buttons, or ask them to reorder the trays?
