perio-bayside-imgIn normal anatomy, tissue fibres (called gingival fibres) attach to the root surfaces, serving to support the teeth as well as the surrounding gum tissues.  Following orthodontic treatment, teeth which used to be out of alignment or rotated have ligaments that are often twisted and become in tension.  The release of these ligaments from the tooth surface using a simple incision (under local anaesthetics) allows them to re-attach in a new non tense position improving the post-orthodontic stability of realigned teeth.
