Tray count is not the whole timeline
The number of initial aligners does not automatically equal the total treatment duration because wear schedule, refinements and pauses can change the calendar.
Different movements have different biological limits
Small alignment changes and complex bite correction do not move at the same pace. The provider should explain which parts of the plan are likely to determine total duration.
Refinements are common
Additional scans and aligners may be used when the first series does not fully achieve the goal. Ask whether the quoted timeline assumes likely refinement stages.
Patient behaviour can extend treatment
Inconsistent wear, missed appointments or repeated lost trays can turn a reasonable estimate into a longer course.
Questions to take to a consultation
- What is the diagnosis and treatment objective?
- Who will personally diagnose, plan and supervise treatment?
- What reasonable alternatives exist?
- What is included in the total fee, including refinements and retainers?
- How often are in-person visits expected?
