A Step-by-Step Look at Clear Aligner Treatment at Emerald City Orthodontics
How does Invisalign work? If you’re comparing Invisalign to traditional braces, understanding what actually happens each time you switch aligners makes the whole process feel a lot less like guesswork. Here’s how the system works, from your first consultation at Emerald City Orthodontics through your final retainer.
Invisalign works by using a series of custom-made, clear plastic aligners that apply gentle, continuous pressure to shift your teeth into their planned positions. Each aligner is digitally designed using iTero scanning technology, worn for about one to two weeks before you move to the next tray in the series, and most patients complete treatment in 12 to 18 months while wearing their aligners 20 to 22 hours a day.

What Is Invisalign?
Invisalign is a modern orthodontic treatment that straightens teeth using clear aligners instead of metal braces. The aligners are made from SmartTrack material, a smooth, durable plastic that fits closely over your teeth and applies gentle, steady pressure to move them safely. Because the trays are nearly invisible, many patients choose Invisalign for its discreet appearance.
Each aligner is custom-made to match your teeth and your treatment goals, and since the trays are removable, everyday tasks like eating, brushing, and flossing stay simple.
How the Invisalign System Works
Invisalign relies on computer imaging technology to plan out your smile transformation. Here is how that process works at Emerald City Orthodontics.
1. Consultation and Assessment
Your orthodontic journey starts with a consultation. During this first visit, the doctor listens to your concerns and checks your teeth for issues like crowding, gaps, overbites, underbites, or crossbites. Catching these bite issues early helps shape your aligner treatment plan.
2. iTero Scanning and Digital Planning
Instead of messy molds, the practice uses iTero scanning to capture quick, digital images of your teeth and bite. These images form the base of your treatment plan, and smart software lets you preview how your teeth are expected to look after treatment before you even start.
3. Custom Treatment Plan
Once your scan results are reviewed, your provider builds a treatment plan specific to you, showing the sequence of how each set of aligners will move your teeth from your starting point to your final smile. Most patients complete Invisalign treatment in 12 to 18 months, though your total treatment time may be shorter or longer depending on your case. The plan will also outline your wear schedule and expected checkups.
4. Getting Your Aligners
Once your custom aligners are ready, your provider checks the fit, gives you your first few sets, and shows you how to put them in and take them out. You’ll also receive a recommended wear schedule, since following it closely is key to steady progress.
How Aligners Move Your Teeth
Invisalign aligners work by applying gentle, controlled pressure to your teeth. Each new set of aligners is slightly different from the last, which causes small movements over time rather than sudden changes. As you move through the aligner series, your teeth gradually shift into better alignment, guided by digital planning and the SmartTrack material.
The Role of Attachments
Some teeth need extra help for trickier movements. Attachments, tiny, tooth-colored bumps, may be placed on certain teeth to help the aligners grip and move them more efficiently. They’re small enough to blend in, so they won’t affect the discreet look of your treatment, and they play a key role in improving Invisalign’s effectiveness for bite corrections, crowding, and rotating teeth.
Which Orthodontic Issues Can Invisalign Treat?
| Orthodontic Issue | Typically Treated with Invisalign? |
| Crowding | Yes, mild to moderate |
| Gaps between teeth | Yes |
| Overbite | Yes, mild to moderate |
| Underbite | Yes, mild to moderate |
| Crossbite | Yes, mild to moderate |
| Severe or complex bite issues | Often better suited to braces |
When Invisalign Isn’t the Right Fit
Invisalign works well for many people, from young kids to adults, covering a wide range of issues like crowding, gaps, overbites, underbites, crossbites, open bite and general mild to moderate bite corrections. For severe or complex bite issues, or teeth that are very crooked, braces might be the better option. Invisalign technology keeps improving, so at your consultation, your provider will help you figure out the best fit for your orthodontic journey.
What a Consultation Can (and Can’t) Tell You Right Away
A consultation gives your doctor a first look at your bite and alignment, but a full treatment plan depends on your iTero scan analysis results and a hands-on exam. Photos or self-assessments at home can’t replace that in-person visit, and only your provider can confirm whether Invisalign, braces, or another option is the right approach for your specific case.
What to Expect Day-to-Day: Wear Time, Checkups, and Aligner Care
Success with Invisalign depends on your commitment. You’ll need to wear your aligners 20 to 22 hours each day to keep teeth movement on track, removing them only to eat, drink anything but water, or clean your teeth. Skipping days or hours can slow your progress and extend treatment.
During treatment, you’ll visit Emerald City Orthodontics every 10 to 14 weeks for progress checks, where the team confirms your teeth are tracking to plan and makes adjustments if needed.
Keeping your aligners and teeth clean matters just as much as wear time. Take the trays out before eating, brush your teeth after meals to keep food and bacteria from getting trapped underneath, and rinse and clean the aligners themselves with cool water rather than hot, since heat can deform the trays. According to Dr. Andy Glassick, one of the top orthodontists in Charlottesville, VA, using cool water instead of hot water not only keeps trays clear but also helps them last longer.
After your final aligner, your provider checks your bite and tooth positions, and may take another iTero scan to confirm your results. Most patients then wear their retainers full-time for the first 6 months before transitioning to nighttime wear indefinitely to protect their new smile and prevent teeth from shifting back.
Frequently Asked Questions
What is the hardest part of Invisalign?
It’s usually when your mouth is adjusting to having something new in it all the time. You might feel some discomfort or pressure as your teeth begin to move, speaking might feel a little awkward at first, and there’s a learning curve to remembering to take the trays out before eating and to brush them regularly.
Can I use a straw with Invisalign?
Yes. Sipping through a straw can actually help minimize contact between sugary or acidic drinks and your aligners. Just rinse your mouth with water afterward to keep things clean.
What is the 30-minute rule with Invisalign?
The 30-minute rule is a guideline to help you get the most out of your aligners: whenever you take your trays out for meals or snacks, aim to have them back in within 30 minutes. This keeps your teeth spending enough time in the aligners to gradually shift into their new positions.
How many hours a day do I need to wear my Invisalign aligners?
Most patients need to wear their aligners 20 to 22 hours a day, removing them only to eat, drink anything other than water, or clean their teeth. Consistent wear leads to more predictable, on-schedule results.
How often will I have checkups during Invisalign treatment?
You’ll typically visit Emerald City Orthodontics every 10 to 14 weeks. These appointments let your provider check your alignment and bite and confirm your teeth are tracking to plan.
