Scratched on surface of tooth enamel?

I had braces for a little over three years, and if you look closely you can see very miniscule scratches on the surface. I used to break my brackets a lot, and I think they must have scratched the surface when the bracket became loose. Is there any way to fix this? I went to the dentist and she told me my teeth looked good and healthy, but she didn't look too closely at my teeth. She just stared at my x-rays for the most part.
