If I were you, I would find a Board Certified Orthodontist and call their office to see if they offer a complimentary consultation. Going to a complimentary consultation will ensure that you feel comfortable with the location, the orthodontist, and get a feel for their expertise. Unlike dentists, orthodontists specifically specialize in moving teeth, that is all they do, day in and day out, so they are the experts in tooth movement. The following link can help you find a Board Certified Orthodontist near you:

Proper orthodontic treatment is not just limited to correcting the alignment of the teeth...it is also important that the upper and lower teeth relate properly together. The "occlusion", or 'the bite' is every bit as important with the function of your teeth as alignment is with the esthetics!
Sometimes (most commonly) it takes longer to correct the occlusion than it does the alignment.
That being said, the length of time in braces is obviously dependant on the degree of difficulty in correcting both the alignment AND the occlusion. This varies greatly! If it's just minor tooth movement of the front teeth, it can sometimes be done with a spring aligner retainer in just a few weeks. On the other hand, if there is significant bite and/or alignment correction...it can take two years or more!
So, the simple answer is this: The total time in braces completely depends on the degree of difficulty of the case!
As soon as the orthodontist does an exam of your dental alignment and occlusion, he/she should be able to give you an idea on how long it will take to correct it!
Hope this helps!!
