With Invisalign, Will my Gap Remain Closed if the Piece of Skin That Seperates the Teeth is Too Large and Isn't Removed?

This is a very common with patients with "gaps" between their front teeth. In order to maximize your results a few things should be considered.

1. A surgical procedure to remove the fibrous band of connective tissue and release the tissue attachment will give you a much better chance of avoiding relapse

2. A bonded retainer that is permanently bonded to the inside part of your upper part is also needed to prevent the dreaded relapse and space opening that may occur.

Yes and no.  Invisalign and traditional braces both move teeth the same way, by applying pressure to the teeth to be moved.  If the space is present because the lower teeth or the tongue is applying pressure to the back of the front teeth forcing them apart, removing the ligament or a piece of gum will not help to keep the space closed.  If the ligament is filling the space and there is enough overbite to move the teeth together the excess tissue should be removed.  Also if swelling or inflamation occurs when the space is closed, the tissue should be removed.
