Invisalign provides an excellent solution for most of the orthodontic problems commonly affecting both teenagers and adults: from malocclusions (incorrect bites), such as overbites and under-bites, to poorly aligned teeth, crowding and jaw problems. This treatment can be used to treat patients of any age who have either never had orthodontic treatment, or who have had braces in the past but whose teeth have shifted back out of place. The Invisalign system is incredibly versatile and has changed the lives and smiles of more than half a million people in the United States alone! It clearly works and almost anyone is a candidate.
