How are craze lines on teeth fixed?

I think my dentist damaged one tooth when I got Invisalign attachments and she used the drill to remove extra composite that was all over my mouth after placing them with the tray. I've had one tooth chipped and with a craze line (white, vertical and quite translucent line) that day. It's not really that noticeable but I'm beyond frustrated. Any restoration that is NOT a veneer can be done? Was it caused by the drill? Thank you in advance.
