Mid line question

[tezarin]

Question for you: well, please visualize what I am about to write or it doesn't make any sense

1) The problem teeth are in my upper jaw mainly the second tooth at the left (start counting from the front tooth), The middle line of my upper jaw is perfectly centered if you know what I mean. The lower jaw's middle line is not centered.
Having said that, they are going to extract the 4th tooth on the upper RIGHT jaw and I was thinking, ok that way all the teeth will move to the right and the upper center line will not going to be centered anymore!

What do you all think??
