How Does Invisalign Work?

Invisalign is an excellent orthodontic option for adults who need orthodontic treatment but don’t want obvious braces. It’s perfectly designed for people who want invisible orthodontics.

The Invisalign system replaces the traditional wire and bracket braces with innovative clear plastic aligner technology. These aligners are discrete, more comfortable than conventional braces, and even removable. If you’re looking for Invisalign in Newcastle, let us tell you a bit about more about what they are, and how they work.

What Is Invisalign?

Invisalign is an orthodontic treatment that can be used as an alternative to the traditional wire and bracket systems. Instead, a gradual series of clear plastic aligners are used to straighten your teeth over time.

These aligners are custom-made for your teeth and your teeth only. A set of aligners is worn for approximately two weeks, then replaced with a new set.

How Does Invisalign Adjust Teeth?

Invisalign actually works on the very same principals as traditional orthodontic treatments: apply gentle but consistent pressure on the teeth to move them into the desired position.

Where Invisalign differs is the tools used to achieve this. Usual braces use brackets that are cemented to teeth and connected with wires. The wires are tightened, pulling on the brackets and applying the force necessary to move the teeth.

Invisalign’s clear plastic aligners fit snugly over the teeth. This tightness is what applies the pressure to move them into place. Since the aligners themselves can’t actually be adjusted, they’re replaced every few weeks to move the teeth to the next stage of the process.

Benefits of Invisalign

There are two significant benefits of Invisalign over traditional braces:

They’re discrete, and they’re removable.

The aligners are made of clear plastic and incredibly difficult to notice. Some patients report that close family members don’t even notice unless they’re told. It’s almost impossible to see the aligners at a distance.

Being removable, it’s easy to eat and clean your teeth with Invisalign compared to traditional braces. There are no special diet restrictions and no special cleaning instructions. You will need to clean your teeth and aligners before putting them back on to avoid bacteria growth, but otherwise, there’s nothing complicated about it.

Another benefit is that Invisalign is a computer-guided system. Detailed digital scans are taken of the teeth, which are then run through sophisticated software. This software maps out the movement of the teeth throughout treatment. By planning the treatment via computer software, Invisalign can move teeth more efficiently and take less time to complete. Keeping gums clean and healthy.

What are the Disadvantages of Invisalign?

The only real technical drawback to Invisalign is the range of orthodontic conditions it can actually cover. Invisalign is best used for light to mild malocclusion of the teeth in most cases. Particularly complex cases are still best treated by traditional orthodontics or a mixture of traditional orthodontics followed by Invisalign. However, the technology is continuously being updated and refined and will be more effective in the future.

Another drawback is that some users are not terribly great at remembering to put the aligners back in. They can’t work if they’re not on! That’s why teenagers usually aren’t considered the ideal candidates for Invisalign.


Like with anything in medicine, the length of treatment depends on the complexity of the case at hand. More complex cases, predictably require longer treatment times. That said, a good ballpark is between 6 months to two years.

Alternatives to Invisalign

The only traditional orthodontic treatment that’s more discrete are lingual braces. These are attached to the side of your teeth facing your tongue (lingual means tongue) and are hidden from view by your teeth. Lingual braces are costly and are more uncomfortable.
