If you're considering straightening your teeth without the hassle of metal braces, you're probably asking, "How does Invisalign work?" Clear aligners like Invisalign - and other invisible orthodontics - are transforming smiles across Melbourne, offering a modern, discreet, and effective solution. But behind every smile transformation is powerful dental technology and a whole lot of science. 


In this blog, we break down the aligner science behind Invisalign, how the treatment works, and why more patients at Bare Smiles Dental Boutique in Essendon are choosing it every day.


What Is Invisalign? A Clear Aligner Overview

Invisalign is a leading brand of clear aligner treatment that gradually shifts your teeth into the correct position using a series of custom-made, removable plastic trays. Unlike traditional braces, there are no metal brackets or wires - just clear, smooth, medical-grade plastic aligners.


Whether you're dealing with crowding, gaps, or bite alignment issues, Invisalign can help - often faster and more comfortably than braces.


How Does Invisalign Work? Step-by-Step Process


🧬 1. Digital 3D Scanning & Smile Simulation

Your Invisalign journey starts with a 3D scan of your teeth using advanced imaging technology like iTero. This creates a detailed model of your mouth, which is used to map out the entire movement of your teeth from start to finish.

⚙️ 2. Custom Aligner Design

Using proprietary AI-driven software, a series of aligners is designed to apply gentle, strategic pressure on specific teeth at each stage. Each set of trays is slightly different to guide your teeth toward their ideal position.


⏳ 3. Aligner Wear & Tooth Movement

You’ll wear each aligner set for about 1–2 weeks, for at least 22 hours a day. The aligners apply light force to shift your teeth in small, precise increments - approximately 0.25 mm per tray.


🧪 4. Attachments & IPR (If Needed)

Some cases require small tooth-coloured attachments to help the aligners grip and move certain teeth more effectively. In some instances, interproximal reduction (IPR) may be used to create space between crowded teeth.


👨‍⚕️ 5. Regular Monitoring & Adjustments

Every 6–8 weeks, you’ll check in with your Invisalign provider to ensure progress is on track. Adjustments can be made as needed.


The Science Behind Invisalign Aligners

Here’s where aligner science truly shines:


✅ Clearwear Material: Clear aligners like Smilers™ are made with a unique thermoplastic that’s designed for optimal flexibility, comfort, and precise force delivery.


✅ Biomechanics of Tooth Movement: Invisalign uses controlled force systems to tip, rotate, intrude, or extrude teeth. It’s not just about pressure—it’s about the right pressure at the right time.


✅ Software-Driven Predictability: AI simulations plan tooth movement in advance, making the treatment highly predictable compared to manual orthodontic adjustments.

FAQs: How Invisalign & Clear Aligners Work


  1. Do Invisalign aligners really move your teeth?

    Yes! They apply targeted force, just like braces—but with modern science, more comfort, and better aesthetics.


  2. Can Invisalign fix overbites or gaps?

    In most cases, yes. Invisalign is effective for mild to moderate bite issues and spacing. Severe cases may need hybrid treatment.


  3. What if I lose an aligner?

    Contact your dentist ASAP. In some cases, you may be advised to move to the next tray early or wear the previous one temporarily.


  4. Does Invisalign hurt?

    Some patients experience mild pressure or soreness, especially when switching to a new set of trays. This means the aligners are working!
