Do you need a second set of Invisalign trays?

For my case, I needed a second tray of Invisalign aligners. My diastema and overbite were severe so the dentist ordered another set for me. To be honest, I was already pretty happy with the result at the end of the first tray, but my dentist explained that it would be best to continue the treatment with another tray.

It is not uncommon that you may need additional sets of Invisalign trays during your treatment.

The determination of how many sets you'll need can vary based on the complexity of your case.

In general, the more complex your case is, then the more sets of trays you may need.
