What is Invisalign & How Does it Work?

What is Invisalign & How Does it Work?

Invisalign was a game-changer in the world of orthodontics when it became available. It allowed patients a discreet option for straightening teeth and treating misalignments - without the need for traditional metal brackets and wires. 


Millions of people have reached successful results with this treatment. Let’s take a closer look at what it is, how it works, and if you may be a candidate for Invisalign. 

What is Invisalign? 

Invisalign is an orthodontic treatment that uses removable clear aligners to transform smiles. Using state-of-the-art 3D-imaging technology, a treatment plan is mapped out and aligners are created to align teeth. 


Invisalign can treat many different orthodontic conditions, including mild or moderate:

  • Crooked teeth
  • Overcrowded teeth
  • Bite misalignments, i.e. crossbites, underbites, overbite, open bites
  • Gapped teeth
  • Slanted teeth
  • Protruding teeth


It is important to note that major or complex orthodontic issues may need to be addressed by alternate orthodontic treatment options. 

How Does Invisalign Work? 

Invisalign treatment includes a series of custom-designed aligners that encourage teeth to move into their new position. These aligner trays are made of clear, durable plastic that is BPA-free and they are created from 3D scans that are taken of your teeth and mouth. The scans are able to predict movement your teeth and can then create custom aligners that will take your smile from point A to point B. 


Aligners are meant to be worn for about two weeks before being switched out to the next one in the series. Slight pressure will be felt as the new aligner begins to guide the teeth. Throughout treatment, regular visits to the dentist will confirm that your treatment plan is on track. 


Invisalign aligners are removable, but in order to be effective, they need to be worn for a minimum of 20 to 22 hours every day. Typical treatment is completed within 18 to 24 months - or sooner. However, not wearing the aligners as instructed could result in delayed (or even failed) treatment. 

Benefits of Choosing Invisalign

There are many reasons why Invisalign has become so popular - and a lot of it has to do with all the benefits. 

  • Discreet treatment thanks to transparent aligners
  • Removable aligners
  • No restrictions on food - you can eat what you want
  • Better oral hygiene as you can brush and floss normally


Best of all, Invisalign is as effective - if not more effective - than traditional braces. 

Are You a Candidate for Invisalign?

While Invisalign can successfully treat many different orthodontic issues, it is not the best option for every patient. In order to be a candidate, you will need to:

  • Have all of your teeth
  • Have a mouth free of tooth decay and gum disease
  • Comply with treatment and wear aligners as instructed
  • Not require complex orthodontic care


Of course, you have to be ready for a new, beautifully straight smile, too!
