I saw 2 orthos who provided 2 different treatments & having hard time deciding. I am 37. Teeth are in order (had braces when young) but have an overbite/jet (3.5mm). Based on 3D xray and teeth exam, 1st ortho said extractions not needed & my results could be achieved in <1yr using invisalign & IPR. 2nd ortho, same diagnostics, but recommended 4 teeth xtractions & did not think IPR would help. Not sure whether IPR will get the results I need; but I'm scared of taking out 4 healthy teeth! Thanks.
