How Long Will It Take to Close a Gap Between Teeth of About 0,06 Inch (1,5 Mm)?

One challenge often overlooked is that gaps that formed once likely will open again unless retention efforts are performed.  This just means wear a retainer after braces/Invisalign.  

To close a 1.5 mm gap likely is only a matter of weeks, depending on the method.

Another way to avoid retainers is porcelain veneers.  This leaves the teeth where they are and fills in the spaces with tooth colored materials (porcelain or composite).  The investment may be more than braces, so a comprehensive consultation with an experienced cosmetic dentist is important.

You have several options for closing a gap between two front teeth. 1) orthodontics (conventional or Invisalign). This would not take long at all assuming the rest of your teeth are in perfect alignment. Probably six months or less. However, you will have to deal with retention for the rest of your life or the space will reopen.  2) Porcelain veneers. This is a two step process where the teeth are first prepared, an impression is taken and the second appointment where the veneers are cemented into place.  3) Composite bonding is the least expensive and quickest way to fix the problem. It is done in a single visit.

Good luck!

Thank you for a great question.Invisalign moves teeth .25mm for each aligner. Assuming your case will permit 1 week aligner wear, it should not take more then 6 weeks to close gap between 2 teeth.The question should be asked though why is there such a big gap on the first place? What prevented teeth to have no space? If the reason for the space is gone, no problem, it will close smoothly. On the other hand, if the cause for the space is still there (like extra tissue between teeth), you might want to address that as well.
