I recently got braces on my bottom 6 teeth, and now my top front teeth have lost colour in patches?

i would bring this to the attention of your denist or the dr who put the braces on they should hear about this cause if it needs attention they can go ahead and fix the problem it doesn't sound normal other people you know that have braces could be the answer should you know somebody who has them it should be of great help if you know anybody call your dentist if you don't
