Most patients who want to straighten their teeth know that orthodontic treatments will improve the appearance of their smiles. However, fewer people are aware that without orthodontic intervention, their facial shape may be adversely impacted. Patients with untreated alignment issues may notice an uneven jaw line (bone that is higher on one side or the other), chin that juts forward, jaw that tilts in toward the neck, and other serious issues. When this occurs, braces can do more than improve the alignment of your teeth. You can completely transform your face shape.
