The process of receiving Invisalign aligners usually takes about four weeks. After the doctor has taken the impressions of the teeth and sent them to the Invisalign laboratory along with notes on how the treatment should progress, most people start to see the difference in just a few weeks. However, the surprising thing is that you'll be able to observe the progress of Invisalign in real time, since the brackets and cables don't hide your teeth. Generally, you can expect treatment to last between 1 and 1.5 years.
While some patients may take longer, others may notice a change in their smile in as little as two weeks. Most Invisalign patients begin to see noticeable results within the first three months, although some may experience a difference in the first two weeks. So, how long does it take for Invisalign to work? Every patient is unique, but you can expect to see a noticeable improvement in your smile in just a few weeks. While some may have to wait three months before their smile gets better, others may have to wait at least five months before they notice any change. The great thing about transparent aligners is that you'll be able to observe the progress of Invisalign in real time.
