How Does Invisalign Work? Your Guide to Virtually Invisible Teeth Straightening

Invisalign. I’m sure you’ve heard of it before.

It’s a teeth-straightening treatment. It’s an increasingly popular alternative to your old-school metal braces, like the ones Prince Harry used to dazzle us in his younger years.

Unlike metal braces though, you’ve probably never seen Invisalign anywhere.

How could you when it’s virtually invisible? That’s why it’s “Invis-align.”

So how does Invisalign work exactly? How can something invisible give you the perfect smile you’ve been dreaming of?

Well, brace yourself for what’s coming next. This tell-all guide will cover everything you need to know about the Invisalign treatment.

Invisalign in London is available here at Bishopsgate Dental Care

How Does Invisalign Work?

Invisalign treatment is practically an invisible way to straighten your teeth using cutting-edge 3D computer-imaging technology.

Invisalign technology takes the current and final straightened position of your teeth, to map out a treatment plan that gradually aligns your teeth.

Then every few weeks, you will replace your current Invisalign with a new set of aligners until you have the perfect smile of yours!

Invisalign Explained: How Do My Teeth Move with Invisalign?

Invisalign moves teeth by applying a controlled force to different parts of your teeth during different parts of your treatment.

Simply put, only specific teeth can move with each new set of aligners you wear.

This is a much more controlled, and less painful way of aligning your teeth in comparison to metal braces.

What is Invisalign Made of?

Invisalign is made out of clear, medical-grade thermoplastic. The material is smooth, so no need to worry about discomfort when you’re sleeping!

What Are the Biggest Benefits of Invisalign?

Oh, where to begin? Unlike traditional metal braces, Invisalign aligners:

  • Are removable. Take them off whenever you need to. Like looking extra cute on your date for instance.
  • Are virtually invisible. These aligners are clear and are much thinner than your average mouthguard.
  • Facilitate better gum health. Because they are removable, you can clean and floss as usual. Plus, they’re not metal, so don’t worry about cutting your gums, either.
  • Have no food restrictions. Eat whatever you want. Chew gum if you want. Without the aligners on of course.
  • Save you time at the dentist. Since you’re not working with metal wires, you don’t have to worry about getting anything tightened.
  • Comfortable. The material is thermoplastic and very smooth. Avoid metal rubbing on your gums or the inside of your cheeks.
  • is a lifestyle choice. When you opt into Invisalign

In other words, it’s the perfect braces alternative for people who want to lead and maintain the lifestyle they already have.

Avoid all the common braces problems when you opt-in to Invisalign.

How Much Does Invisalign Treatment Cost?

For the average adult, the cost can range from 2,500 and 5,500 pounds.

How Long Does Invisalign Treatment Take?

Short answer: it varies. Why?

Every person’s plan is custom-made to their needs. Why?

Depending on the number of dental conditions you have (e.g., gapped teeth, overly crowded, etc.) will impact the length of your Invisalign treatment.

Definitely take advantage of our free consultation to see what your plan looks like.

How Long Do I Have to Wear Invisalign Each Day?

You should wear your Invisalign at all times except for when you need to eat or brush your teeth.

That means you will need to wear them in your sleep. If you’re afraid you won’t be able to fall asleep with them on, don’t worry!

Each aligner is custom-made for your teeth, so they should feel comfortable and smooth to the touch.

Do I Need to Clean My Invisalign Aligners? If So, How?

Yes. You will need to clean your Invisalign aligners. The simplest way to clean them is to rinse them in lukewarm water and brush them with your toothbrush each night.

You can also purchase Invisalign’s official cleaning kit.

Is Invisalign Treatment Painful?

Some people experience some minor discomfort for the first few days with their new Invisalign aligners.

However, this will go away after a few days as your teeth adjust to the shape of your aligner.

This is normal because each set of aligners is placing pressure to shift your teeth gradually to their desired position.

Other than that, your Invisalign aligners should feel comfortable since they’re custom-made to your teeth!

How long does invisalign last?

Well technically nothing is forever, BUT this is an important step to keep your teeth straight and stable.

Otherwise, you may risk relapse, i.e. your teeth have shifted after you’ve completed your treatment.

If you want to avoid relapse, wear your retainer when you sleep.

Or think of it this way. Getting Invisalign is an investment for your smile, so protect your investment! Wear retainers per doctor’s orders.
