If you’ve been thinking about straightening your teeth but aren’t excited about traditional metal braces, you’ve probably heard about Invisalign. This popular orthodontic treatment has transformed smiles for millions of people worldwide, but many patients still wonder: How does Invisalign work? At Nivedita Nijhawan, DDS, in Fresno, CA, we love helping patients understand their treatment options, so let’s break down exactly how this innovative system works.
The Science Behind How Invisalign Straightens Teeth
Invisalign treatment uses a series of custom-made, clear plastic aligners to gradually shift your teeth into their desired positions. Think of it as gentle, consistent pressure applied in exactly the right places at exactly the right times. Each aligner is slightly different from the one before it, creating incremental movements that add up to a beautifully straight smile.
The aligners are made from a patented thermoplastic material called SmartTrack, which is designed specifically for the Invisalign system. This material applies a gentle, constant force to your teeth while being comfortable enough to wear for 20–22 hours each day.
Your Invisalign Treatment Journey
Digital Imaging and Treatment Planning
Your Invisalign journey begins with a consultation at our Fresno office. Dr. Nivedita Nijhawan will take digital scans or impressions of your teeth, along with photos and X-rays. Using advanced 3D imaging technology, we’ll create a precise digital model of your mouth and develop a customized treatment plan that maps out exactly how your teeth will move throughout the process.
You’ll even get to see a virtual preview of your future smile before you commit to treatment!
Receiving Your Custom Aligners
Once your treatment plan is finalized, your custom aligners are manufactured and sent to our office. You’ll receive several sets at a time, typically enough for several weeks of treatment. Each set is numbered and designed to be worn in sequence.
Wearing and Switching Your Aligners
Here’s how Invisalign treatment works on a day-to-day basis:
- Wear each set of aligners for 20–22 hours per day
- Remove them only for eating, drinking anything other than water, and brushing your teeth
- Switch to the next set of aligners approximately every 1–2 weeks (as directed by Dr. Nijhawan)
- Visit our office periodically so we can monitor your progress
Invisalign Explained: What Makes It Different
What sets Invisalign apart from traditional braces is its virtually invisible appearance and removable design. The clear aligners are difficult for others to notice, making them perfect for adults and teens who want a more discreet orthodontic option.
The removable nature also means you can maintain your normal oral hygiene routine without navigating around brackets and wires. Simply take out your aligners, brush and floss as usual, and pop them back in.
How Long Does Invisalign Treatment Take?
Treatment length varies depending on your specific needs, but most patients complete their Invisalign treatment within 12–18 months. Some minor cases may take as little as six months, while more complex cases might require up to two years.
The key to success is consistency—wearing your aligners as directed and keeping your scheduled appointments with Dr. Nijhawan ensures you’ll achieve your dream smile on schedule.
