How long will it take to close this gap with invisalign? (Photo)

On the surface, your question sounds relatively simple but your photo makes me want to ask many more questions. Does the photo represent your "normal" bite (the normal position your upper and lower teeth fit together)? If it is, you have more significant issues than the small space. If it is not your normal bite, an accurate answer will be most difficult let alone a wild guess. Sorry

Hi Kb0001,Thank you for posting your question.  In general Invisalign can close the gap between the front teeth.  Your case would have to be worked up to see how long it would take.  A clin-check can be made to give you a 3-dimentional animation of the movements necessary to achieve your desired outcome and give you an estimated time of treatment.   Although your concern is the gap between your front teeth you should have your entire mouth evaluated to give you the best long term outcome. It may or may not have an effect on how your upper and lower jaw relate to each other. What I notice in the picture you posted is that your Lower front teeth sit in front of the upper teeth and there is an open bite. An open bite is when your upper front teeth don't touch the lower front teeth and there is a space between the two. This situation can put a lot of pressure on the back teeth.  Do you clench or Grind your teeth?  All this needs to be addressed when your case is being worked up.  Hope that helps!  Good Luck!Best, Dr. Supriya Verma

It is impossible to tell from one photo, but typically closing a gap like this should take 3 to 6 months. The big concern is your bite. When you close your teeth together, your lower front teeth hit your upper front teeth and help keep this gap open. The real question is how long it will take to correct the bite, not to just close the gap. That may take 9 to 12 months. Talk to your Invisalign provider.
