Will Invisalign be able to push my front tooth forward by about 1 mm? If so, how long would this process take? (Photo)

 good job with the photos! Yes, one tooth can be addressed. If that is the only thing you want done, the left front tooth can be pushed out with a clear aligner. In my office, for this type of treatment, we use and Essex Aligner that addresses only the desired treatment. This type of treatment may require slenderizing adjacent teeth to allow this tooth to move forward. This should only take 4 to 6 weeks to move the tooth into the desired position! The Essix Aligner treatment  is much more cost-effective for this treatment than Invisalign.

While Invisalign can be performed for the movement of even one tooth or an entire arch, it's important to look at "the whole picture" in the planning process. For example, one malpositioned tooth in your smile may have been caused by an improperly positioned lower tooth or a wear pattern in your bite causing one tooth to look longer or move asymmetrically. Sometimes the cause of an aesthetic problem,even a slight aesthetic problem, can be very different that the symptom (appearance) which can begin as I tooth. So my advice is not to be too short sighted and allow your dentist or orthodontist to treatment plan you properly. You will be much happier in the end.

Yes, it is possible to move only 1 tooth with Invisalign.  From the photos, it appears that a bit of space may need to be created between the front 2 teeth to make this possible.  Alternatively, the teeth on either side could be moved slightly to allow for correction.  In any case, this is a very simple Invisalign case that would be completed easily within 5 aligners (10 weeks).
