Is there a way to restore a front tooth after the dentist filed down too much? (photos)

I had a very small chip on my front tooth. I went to the dentist to see what she could do so that the edge would not bother me and she said that she could not bond it because it would fall off. She told me my only option was to file it down a tiny bit just to smooth out the edge and that I wouldn't be able to notice. However, she took off more than I was expecting and now the tooth is a different shape than the other front tooth. When I bite down only one front tooth touches.
