If you’ve ever wished for a straighter smile without the brackets and wires of traditional braces, you’re not alone—and you’re not out of options. Invisalign has transformed orthodontics by offering a discreet, comfortable, and high-tech way to align teeth. But how does Invisalign actually work?


At Belle Mead Orthodontics, we’re not just here to straighten your teeth—we want to help you understand the process behind your smile transformation. Let’s break down the science of Invisalign and what makes it such an effective treatment.



🔍 Step 1: Digital Scanning – The Foundation of Your Custom Plan

Every Invisalign journey begins with a digital scan of your mouth using advanced 3D imaging technology—no goopy impressions needed. At Belle Mead Orthodontics, we use the iTero® scanner to create a detailed model of your teeth and bite.


This scan is then uploaded into specialized software that maps out the exact movements your teeth need to make—from start to finish.


🧠 Step 2: Smart Technology & Treatment Planning

Using your 3D scan, we create a custom treatment plan that shows each stage of tooth movement. This plan isn’t just for us—it gives you a preview of your future smile before you even begin treatment.


Invisalign’s software uses algorithms and biomechanics to determine the most efficient path to your desired results, often with fewer in-office visits than traditional braces.


🦷 Step 3: Your Aligners – Designed for Precision

Once your plan is approved, Invisalign fabricates a series of clear aligners made from their patented SmartTrack® material, engineered specifically for gentle yet effective tooth movement.


Each set of aligners is slightly different from the last and is worn for about 1–2 weeks, gradually shifting your teeth into place. The material is flexible for comfort, yet strong enough to deliver consistent force.


⏱️ Step 4: Wearing Your Aligners – Consistency Is Key

To get the best results, aligners must be worn 20–22 hours per day. You only remove them for eating, drinking (anything other than water), brushing, and flossing.


Every few weeks, you’ll switch to a new set of aligners as your teeth continue to move according to your custom plan.


📈 Step 5: Monitoring Progress

You’ll visit Belle Mead Orthodontics every 6–10 weeks so we can ensure your treatment is on track. These appointments are usually brief, and no adjustments are needed—just progress checks and guidance.


In some cases, small attachments (or “buttons”) may be placed on your teeth. These are tiny, tooth-colored shapes that help the aligners apply the right force to move certain teeth more precisely.


✅ Step 6: Retainers & Smile Maintenance

Once your treatment is complete, you’ll receive a custom retainer to maintain your new smile. Wearing it as directed is essential to prevent teeth from shifting back over time.


Why Invisalign Works So Well

  • Custom Fit: Each aligner is made for your exact smile.

  • Predictability: You (and your orthodontist) can see the entire journey from the beginning.
