Most people who wear Invisalign wear the Invisalign for between 12 months to 18 months.
The actual time that a person needs to wear Invisalign can vary from person to person but most wear the Invisalign for 18 months and then they can stop wearing it.
The dentist who you get the Invisalign from and installed will determine exactly how long your treatment will take based on your specific needs.
The Invisalign treatment time takes between 12 to 18 months to see full results from the Invisalign treatment but you should start seeing some results from the Invisalign within a few weeks of beginning to wear the Invisalign.
If you remove the Invisalign before the dentist says to then the treatment won't work.
You will need to wear your Invisalign for at least 22 hours per day for the Invisalign to be effective but the more you wear the Invisalign the better.
