If you’re thinking about straightening your teeth with Invisalign, then you have the first question: how long does it take for Invisalign to work? Invisalign is a modern orthodontic treatment that progressively makes use of clean, removable aligners to transfer its teeth into the right position. Unlike traditional braces, invisalign aligners are almost invisible, comfortable and easy to control for your routine. Treatment time varies for everybody, however in common, most patients complete their journey in 12 to 18 months.
Invisalign Treatment Duration: What Is Typical
Every smile is different, which means that the invisalign timelines can be different.
Here is a common guide:
- Light cases (small intervals or slight crowding): Around 6-9 months
- Medium case (noticeable missing, overbite, or crossbite): Around 12-15 months
- Complicated cases (severe crowds, bite issues, or missing of jaw): often 18 months or more
