This is Ms A, she had braces when she was a teenager. She wore some retainer plates for a few years after treatment was completed and now her teeth have somewhat drifted back. She works in a media related job and does not wish to have braces done again. We offered her an Invisalign Express option and her case was treated out over 20 weeks. We have now placed her on upper and lower fixed orthodontic retainers that are placed on the back of her upper and lower front teeth. They are not visible and we have also modified the design so she could still floss and clean as per normal.*
Our teeth sit in a buffer zone between the muscle balance of the lip, cheek, tongue and jaw muscles. As we age (no matter if we are 10, 20, 30, 40 years old or beyond) the muscle tension of these structures change. As a result the teeth may drift according to these muscular changes and tend to go back to their original position – crooked teeth. Therefore, we will need to have some form of semi-permanent retention if we wish to have perfectly aligned teeth.
