I just got my attachments & was disappointed to have all this extra resin / bonding AROUND the attachments. Is this amount of "flash" (I did some research & think this is what it's called) acceptable? Won't even 1mm of extra bonding negatively affect how my aligners fit and thus my treatment? If there's extra surface between the enamel and the aligner, that wasn't anticipated, doesn't that hurt my treatment & change the movement? It's on all of them, but hard to photograph... PLEASE help, Thx!
