I'm trying to decide between paying around $6000 for an orthodontist "premier provider" or my dentist, a "preferred provider" who would only charge me $3400. I have a pretty straightforward case, orthodontial relapse since I had braces when I was a kid. Just some overcrowding on my bottom teeth. I already had my full consultation, Invisalign said I would need 16 trays. Not sure what to do! I just got engaged so I want my teeth to be straight for my wedding.
