One of my Front Tooth is Slightly Pushed Front Than the Other, What Can I Do?

From the information you have given us it sounds like you should be able to use Invisalign to correct your malocclusion. After the invisalign to straighten your teeth and correct your bite you may want to use a permanent retainer to keep it in the right position.

You are correct. The mal-positioned lower tooth is forcing the upper tooth into the same malposition. Sounds like Invisalign might be your answer. And then a permanent lingual retainer behind the teeth to keep them from relapsing.

It appears that a removable retainer could possibly be used to close the front space and to move the one tooth back some.  This would be the most conservative treatment and the most economical.  However, I would advise to do a full, extensive exam with your orthodontist to see if this limited type of treatment would be indicated.  As with any type of limited types of treatment, you usually get a limited result....but sometimes the limited result will address the patients chief concern.
