How Long Does Invisalign Take to Straighten Teeth?

If you're considering Invisalign to straighten your teeth, one of your first questions is probably: how long will it take? While treatment length varies for every patient, the clear aligner system is known for being both efficient and discreet. At La Mirada One Dental, we customize every Invisalign plan to fit your unique smile.

Average Invisalign Treatment Time

On average, Invisalign takes 12 to 18 months to straighten teeth. However, some patients begin to see results in just a few weeks, and minor corrections may take as little as 6 months.

Invisalign often works faster than traditional braces for mild to moderate alignment issues.

Factors That Affect Invisalign Treatment Time

Several things can influence how long your Invisalign treatment will take:

• Severity of your case: Mild crowding or spacing may be corrected in under a year, while more complex bite issues can take longer.

• Compliance: Wearing your aligners for the recommended 20–22 hours a day is crucial.

• Age: Teens often see slightly faster results due to ongoing jaw growth.

• Number of aligners: More aligners usually indicate a longer treatment timeline.

Tips to Stay on Track (or Even Finish Sooner)

• Wear aligners as directed—don’t skip days.

• Avoid taking them out too often, especially for long periods.

• Keep up with dental checkups to monitor progress and address any delays.

• Clean your aligners regularly to avoid plaque buildup and ensure a snug fit.

What Happens After Invisalign?

Once your aligner series is complete, you'll receive a retainer to maintain your new smile. Wearing your retainer as directed is key to preventing teeth from shifting back.

Is Invisalign Right for You?

Invisalign is an excellent option for teens and adults with mild to moderate alignment concerns. From crowded teeth to small gaps and even some bite issues, Invisalign offers a nearly invisible way to get the results you want without the wires and brackets of traditional braces.
