What is Invisalign and how does it straighten my teeth?
If you’ve heard friends or colleagues talking about Invisalign, you might be wondering what it actually is and how it works. Here’s a simple guide to help you understand the basics.
What is Invisalign?
Invisalign is a modern alternative to traditional braces. Instead of metal brackets and wires, it uses a series of clear, removable retainer like trays (called aligners) to straighten your teeth. Each set of aligners is custom-made for you, designed to move your teeth gently over time.
How does it work?
The process starts with a digital scan of your teeth. Using advanced 3D technology, we create a plan that shows how your teeth will move step by step. You’ll be given a series of aligners to wear, usually changing them every 1–2 weeks.
Each aligner applies gentle pressure to specific teeth, gradually guiding them into the right position. Because the aligners are removable, you must take them out to eat, drink, brush, and floss - which makes life a lot easier compared to fixed braces.
Most people need to wear their aligners for 20–22 hours a day, and treatment can take anywhere from a few months to around 18 months depending on your case.
What are Invisalign aligners made of?
The aligners are made from a specially designed clear plastic called SmartTrack®. This material is strong, flexible, and completely free from BPA and other harmful chemicals. It’s smooth too, so it won’t irritate your mouth the way metal braces sometimes can.
Why patients like Invisalign
• They’re virtually invisible – most people won’t even notice you’re wearing them.
• They’re removable – so you can enjoy your favourite foods without restrictions.
• They’re comfortable – no wires or brackets, just a smooth plastic fit.
• They’re predictable – thanks to digital planning, you can see your smile transformation before you even start.
