Can I get braces with a missing upper left 1st bicuspid? (Photo)

I went to get braces and the orthod recommended I get my dental work done first. I had to get a few fillings and then a major problem came to head, I was recommended for a root canal for tooth D12 and if it was too decayed it would be extracted. I was wondering would this throw my midline off with a missing bicuspid?
