If with braces you would have to have teeth out will you with invisalign?

Rather than removing teeth, my children were fitted with retainers that changed the shape of their upper palate to fit their teeth. We cranked the retainer a quarter turn every week for almost a year. This allowed the second row of teeth to realign and for others to come down as they should. At the end of that time, they could have had a short time with braces, but we decided that things looked great.

that 'retainer' placed on the upper hard palate is actually called an expander. it literally breaks you maxilla bone, leaving room for more teeth and making it easier for braces.
