Dr Filed my Front Teeth Without Asking. I Am So Unhappy W/ This Permanent Change. Why?

Dr. filed my front teeth after doing scheduled work. I didn't know what he was doing & thought "is he filing my teeth or something?" At home, I was shocked. I don't look hideous from it.,but it's a permanent change to my appearance.This isn't a haircut, fingernails, a tan, or a tattoo. If asked, I would have def. said 'no'. I had orthodontic work done 25 years ago-big $. In 60 sec., I'm forever changed. Maybe10-15% of the front teeth now gone, is it possible to reconstruct back to where I was?
