Invisialing Math Question. 45 Trays Total, Or 90?

September 13, 2013
Asked By:2ndqtrlife in Georgia, GA

I went to my orthodontist today and she said 45 trays for my treatment . Of course, after the initial shock forgot to ask how would that work ? Is it 45 for the top and bottom teeth combined or 90 trays total ? Can the number of trays go down if treatment moves along faster than the clinical check predicted ? Thanks .
