Both Invisalign and braces are approved by the Food and Drug Administration (FDA) for the orthodontic treatment of malocclusion.
Invisalign is typically used to treat mild to moderate dental concerns. Braces are often preferable and more effective in more complex cases, such as rotated teeth, large gaps, or severe crowding.
People typically wear Invisalign for 12 to 18 months, but some people may only need them for six months. By contrast, fixed braces often take one to two years to work. The length of time depends on many individual factors, so talk to your orthodontist about what to expect for your case.
