Wisdom Teeth Have Caused Bottom Front Teeth to Overcrowd. How to Fix? (photo)

The best long term solution will be to extract the wisdom teeth, then have an orthodontic consultation.  Full bracket orthodontics will give you the most predictable result aesthetically and align your teeth into the most ideal occlusion (bite) possible.  Good luck. 

There is still much debate on whether or not wisdom teeth actually cause crowding of the lower front teeth as we still see it even once the wisdom teeth are removed. That said, there are several ways to treat the crowding. If you simply extract the tooth you will be left with a space that I presume you would want closed. The first thing to do is to see an orthodontist or a general dentist who does orthodontics.

Based on this one photo it does appear that best option is to pull that tooth and use the space to straighten the remaining teeth.  The straightening can be accomplished with invisalign or conventional braces.  Have a consultation with an orthodontist or general dentist experienced in invisalign and conventional orthodontic treatment.

The treatment will depend if you want braces  ,invisalign or not, some patients do not want to struggle with this long time proceedures, and they just want a quick solution, there several options if this is your case, braces, or other type of orthodontic, treatments, will take at least 1 year, other options, just 12 days.
