Told only a few attachments on the sides.They're on nearly all my teeth.Getting sores.Sharp. Difficult to eat. Options? (photos)

Is there anything at all that can be done at this point? This looks awful. My teeth aren't that crooked. I was told there would be a few attachments on the sides. I'm also getting sores in my mouth from the aligned trays. The sharpness of these attachments makes it painful to eat. I was told they would be on for the duration of the treatment. I also whiten my teeth often. What can be done to keep the attachments white as I've been reading they stain easily? Are there clear ones available?
