Invisalign has completely transformed the field of orthodontics, offering a clear, comfortable, and removable alternative to traditional metal braces. With millions of patients treated globally, it’s no surprise that many people are turning to this modern solution to straighten their teeth discreetly.
But the question remains: How does Invisalign work? If you’re new to clear aligners or considering orthodontic treatment, this comprehensive beginner’s guide breaks down everything you need to know—step-by-step—about how Invisalign works, its technology, treatment process, and what you can expect from start to finish.
What is Invisalign and How Does It Work?
Invisalign is a type of clear aligner therapy used to correct misaligned teeth and bite issues. It involves wearing a series of custom-made, transparent trays that gradually move your teeth into better alignment. Unlike traditional braces, there are no wires or brackets—instead, Invisalign aligners are virtually invisible, easily removable, and designed for maximum comfort.
Step-by-Step: How Invisalign Works
1. Initial Consultation With an Invisalign Provider
Your journey begins with an in-person consultation with a certified Invisalign provider. This could be a dentist or orthodontist who has been trained to administer Invisalign treatment.
During this visit:
- Your dental health and bite are examined.
- Photos, X-rays, and digital scans (or impressions) of your teeth are taken.
- You’ll discuss your goals (e.g., fixing crowding, gaps, overbites, etc.).
- The provider determines whether you’re a suitable candidate for Invisalign.
Note: Invisalign works best for mild to moderate cases. Severe bite or alignment issues may still require traditional braces or a hybrid approach.
2. Digital 3D Treatment Plan Using Invisalign Technology
Once your dental impressions or scans are captured, your provider uses Invisalign’s proprietary software to create a custom digital treatment plan.
This plan maps out:
- The current position of your teeth
- The series of movements needed to achieve perfect alignment
- The number of aligners you’ll need
- An estimated treatment timeline
- A 3D simulation of how your teeth will move and what your smile will look like at the end
This preview is often a big confidence booster—it shows you the result before you even start!
3. Custom Fabrication of Invisalign Aligners
Once your treatment plan is approved, Invisalign uses advanced 3D printing technology to create your custom aligners. They are made from a patented material called SmartTrack®, which is:
- BPA-free and safe for daily wear
- Designed for optimal fit and comfort
- Engineered to apply consistent, gentle pressure
Depending on your plan, you may receive several aligners at once or in batches during your treatment.
4. Wearing the Aligners (20–22 Hours Daily)
When you receive your first set of aligners, it’s time to begin the transformation. You’ll wear each aligner tray for 20 to 22 hours a day, only removing them to:
- Eat or drink (anything except plain water)
- Brush and floss
- Clean the aligners
Each aligner is typically worn for 1 to 2 weeks, depending on your provider’s instructions. Then you switch to the next tray in the series, each one moving your teeth closer to the final result.
5. Gentle, Controlled Tooth Movement
Here’s where the science happens. Invisalign aligners work by applying precise, gentle force to specific teeth based on your treatment plan. Over time, the pressure moves your teeth in small increments.
You might feel mild discomfort or pressure when switching to a new aligner—this is normal and a sign that your aligners are doing their job.
6. Regular Monitoring and Progress Checks
Throughout your Invisalign journey, you’ll have check-ins every 6–8 weeks with your provider. These appointments help ensure your teeth are shifting correctly and give you the chance to:
- Ask questions
- Pick up your next batch of aligners
- Make any necessary adjustments to your plan
Some providers offer virtual monitoring through apps, allowing you to check in remotely and reduce in-person visits.
7. Completion of Treatment and Wearing Retainers
After you’ve completed all the trays in your plan, your smile will be straighter and healthier—but to keep it that way, you’ll need to wear retainers.
Retainers help prevent your teeth from moving back (a process called relapse). Most people wear retainers full-time for a few months, then only at night.
Invisalign offers Vivera retainers, made from a durable material designed to maintain your results long-term.
Benefits of Invisalign: Why People Choose It
- Virtually invisible – No brackets or wires, making it ideal for professionals and teens alike.
- Comfortable – Smooth plastic means no poking wires or cuts inside your mouth.
- Removable – Eat, drink, brush, and floss like normal—just take them out.
- Customised – Aligners are tailored specifically to your teeth and treatment plan.
- Fewer clinic visits – Fewer emergencies and check-ups compared to traditional braces.
How Long Does Invisalign Take?
Treatment time varies depending on the complexity of your case. On average:
- Mild cases: 6–8 months
- Moderate cases: 12–18 months
- Severe cases: 18–24+ months
Your provider will give you a more accurate estimate based on your unique dental needs.
How Much Does Invisalign Cost?
In 2025, the cost of Invisalign in Nigeria typically ranges from:
$4,000 – $6,000 (converted to naira at the current exchange rate)
The final price depends on:
- The complexity of your case
- Your provider’s experience
- Location and additional services (e.g., retainers, checkups)
Most dental clinics offer payment plans to help make treatment more affordable.
Who Is a Good Candidate for Invisalign?
Invisalign works well for:
- Mild to moderate crowding or spacing
- Overbites, underbites, and crossbites
- People seeking a discreet, comfortable option
- Adults and teens willing to wear aligners responsibly
If you have severe bite issues or jaw alignment problems, your provider may recommend other options or a combination of Invisalign with other treatments.
