How Long Does It Take For Invisalign To Work?

The Invisalign system is one of the most popular orthodontic treatments available. But how long does Invisalign take to work? In this article, we answer your main Invisalign questions and explain more about the treatment process.

Invisalign is an innovative form of invisible braces that have revolutionized orthodontic treatment. The Invisalign aligners are made from clear plastic, making them almost undetectable when worn on teeth and gums. Invisalign aligners gradually move teeth into position over some time. How long it takes for Invisalign to work depends on many factors, including the severity of misalignment, completion rate, and patient compliance.

The Invisalign Process

Invisalign works by gradually shifting the teeth into their desired positions. For Invisalign to be effective, patients must wear the aligners for at least 22 hours daily. Invisalign treatment typically lasts between 6 and 24 months, depending on factors such as the case’s complexity and patient compliance.

Invisalign Aligners: Invisalign aligners are custom-made from comfortable, clear plastic to precisely fit the patient’s mouth. The aligners apply gentle pressure to move teeth into their proper positions over time. With regular use of Invisalign, teeth can be corrected in as little as six months.

Invisalign Visits: To monitor Invisalign progress, patients visit an Invisalign provider at least every eight weeks. During these visits, the Invisalign provider will check that teeth are shifting as expected and make any necessary adjustments to the aligners.

Invisalign Maintenance: Once patients have completed their Invisalign treatment, they need to wear retainers to keep their teeth in position. Retainers should be worn for at least twelve hours each day and replaced if they become too loose or broken.


In conclusion, Invisalign is a safe and effective orthodontic treatment that can improve misaligned teeth in as little as six months. For Invisalign to succeed, patients need to wear the aligners for at least 22 hours each day and visit an Invisalign provider regularly. After Invisalign treatment, retainers should be worn to keep teeth in position.
