Invisalign, a revolutionary development in orthodontic treatment, has emerged as a sought-after alternative to traditional metal braces for teeth straightening. This innovative system utilises clear aligners, custom-designed to fit snugly over your teeth, gently guiding them into their correct position. Unlike traditional braces’ conspicuous metal brackets and wires, Invisalign aligners are virtually invisible, offering a discreet solution for those seeking a new smile.

So, how does Invisalign work? The process begins with an initial consultation at a dental clinic, where an Invisalign provider assesses your oral health and determines if Invisalign suits you. Using advanced Align Technology, such as the iTero Element scanner, the dentist creates a precise 3D image of your teeth. This image forms the basis of a customised treatment plan, outlining the step-by-step transformation of your smile.



Each set of custom aligners is worn for about two weeks before moving on to the next set in the series. You’ll notice a gradual shift in your teeth alignment as you progress through the treatment. Invisalign’s effectiveness is in its ability to straighten teeth and maintain oral health, as the aligners can be easily removed for regular brushing and flossing.

Throughout the Invisalign treatment, periodic check-ups with your dentist ensure the treatment progresses as planned. The total treatment time varies depending on the case’s complexity, ranging from a few months to a few years.

This article aims to delve deeper into how Invisalign works, exploring the technological advances that make it an effective teeth-straightening treatment. From understanding the custom aligner system to recognising the benefits of traditional braces, we’ll cover all aspects of the Invisalign journey towards achieving straighter teeth and a confident smile.

What is Invisalign? 

Invisalign, a groundbreaking addition to orthodontic treatment, represents a modern approach to straightening teeth. Introduced in the late 1990s, this system uses a series of custom aligners made from clear, flexible plastic to move teeth into their correct position gradually. These aligners are virtually invisible, setting Invisalign apart from traditional metal braces, which are more noticeable due to metal wires and brackets.

The key difference between Invisalign and traditional braces is their aesthetics and functionality. While traditional braces are fixed to the teeth, Invisalign aligners are removable, offering greater convenience for eating, brushing, and flossing. This aspect significantly enhances oral health during the teeth straightening treatment. Additionally, Invisalign aligners’ comfort and discreet appearance make them popular among patients who prefer a less noticeable orthodontic solution.

How-Does-Invisalign-Work-aligners-balmoralThe Invisalign system is designed for various dental issues, ranging from crowded teeth to deep bite corrections. The treatment involves a series of aligners, each worn for about one to two weeks before switching to the next in the series, gradually shifting the teeth to their desired position. The entire process is monitored by an Invisalign provider, typically a dentist or dentist, who ensures the aligners fit perfectly and the treatment progresses as planned.

Invisalign has transformed the field of orthodontics, offering an effective, virtually invisible alternative to traditional metal braces for achieving a straighter, healthier smile. With its custom-designed aligners and patient-friendly approach, Invisalign continues to be a preferred choice for teeth straightening treatment.

The Science Behind Invisalign

The science behind Invisalign’s effectiveness in orthodontic treatment lies in its innovative use of materials and technology. Invisalign aligners are made from a patented thermoplastic material known as SmartTrack, which is BPA-free, ensuring safety and comfort for the wearer. This material is specially engineered to provide a constant force for teeth straightening while being virtually invisible when worn.

Central to the Invisalign system is the advanced 3D imaging and printing technology. During the initial consultation at a dental clinic, an Invisalign provider uses the iTero Element scanner to create precise 3D digital images of the patient’s teeth. This eliminates the need for traditional physical impressions, which can be uncomfortable for the patient. These digital images form the basis of a customised treatment plan developed using Align Technology’s software.

The treatment plan meticulously maps out the tooth movement required to achieve straighter teeth. Based on this plan, a series of custom aligners are produced using state-of-the-art 3D printing technology. Each aligner is designed to slightly adjust the teeth’s position, a process that is carefully calculated and monitored throughout the treatment.

This combination of custom-made aligners and precise treatment planning ensures effective teeth straightening treatment, distinguishing Invisalign from traditional braces, which rely on metal wires and brackets. The clear aligners fit snugly over the teeth, gently moving them into the correct position over time. This advanced approach to orthodontics promotes better oral health and offers a more aesthetically pleasing and comfortable solution for patients seeking a new smile without the visibility of metal braces.

Customisation Process

The customisation process of Invisalign treatment is a key step in achieving a new smile. It starts with an initial consultation at a dental clinic, where the Invisalign provider, typically a dentist, thoroughly examines the patient’s teeth and oral health. This consultation is crucial to determine if Invisalign suits the individual’s teeth straightening needs.

During this appointment, the Invisalign provider uses advanced technology, such as the iTero Element scanner, to create a highly accurate 3D digital model of the patient’s teeth. This state-of-the-art imaging replaces the need for traditional physical impressions, which can be uncomfortable. The digital model captures the unique contours of the teeth and gums, providing a detailed view of the current alignment and bite issues.

How-Does-Invisalign-Work-placement-balmoralFrom these 3D images, the dentist develops a customised treatment plan tailored to the patient’s specific orthodontic requirements. This plan outlines the series of movements that the teeth will undergo and estimates the treatment duration. The Invisalign aligners are then custom-manufactured based on this plan, ensuring they fit perfectly and comfortably in the patient’s mouth.

Throughout the Invisalign treatment, the dentist plays a critical role, overseeing the progress and adjusting the treatment plan as needed. Regular check-ups are scheduled to ensure the aligners fit well and the teeth move into their new position as anticipated. This personalised approach enhances the treatment’s effectiveness and ensures the patient’s comfort and satisfaction with their journey towards straighter teeth.

Treatment Process 

The Invisalign treatment process is a meticulously planned journey towards straighter teeth using custom aligners. These clear aligners are designed to be worn for at least 20 to 22 hours daily, only removed for eating, brushing, and flossing. This commitment is crucial for the success of the teeth straightening treatment, ensuring that the tooth movement proceeds as per the treatment plan.

Patients receive a series of aligners, each set worn for about one to two weeks before switching to the next in the sequence. This frequent change is a key step in the Invisalign system, as each aligner is slightly different from the previous one, gradually shifting the teeth into their correct position. The aligners fit snugly over the teeth, applying gentle pressure to guide them into the desired alignment.

The average duration of Invisalign treatment varies depending on the individual’s orthodontic needs. Typically, treatment can last anywhere from 6 months to 2 years, average being around 12 to 18 months. This timeframe can be shorter or longer based on the case’s complexity and how well the patient adheres to the wear time guidelines.

Regular check-ups with the Invisalign provider are essential throughout the treatment. These appointments ensure that the aligners fit well and the teeth move as expected. Adjustments to the treatment plan may be made during these visits to address any bite issues or refine the teeth’ position.

Invisalign aligners offer a virtually invisible and comfortable solution for teeth straightening, making them a popular choice for those seeking an alternative to traditional metal braces. Their ease of use and effectiveness in achieving a new smile have made them a sought-after orthodontic treatment.

Maintenance and Care 

Maintaining and caring for Invisalign aligners is crucial for the success of orthodontic treatment. To ensure optimal results, it’s important to clean the aligners regularly. Rinse them every night and brush gently with a soft-bristled toothbrush to remove any plaque or food particles. Avoid using hot water, as it can warp the plastic.

In addition to daily cleaning, Invisalign aligners should be soaked in denture or Invisalign cleaning crystals to keep them clear and free from harmful bacteria. This routine maintains the virtually invisible appearance of the aligners and promotes better oral health.

How-Does-Invisalign-Work-care-balmoralFor the best results, patients should follow the wear schedule prescribed by their Invisalign provider, typically wearing the aligners for 20 to 22 hours daily. Removing the aligners only for eating, drinking anything other than water, brushing, and flossing ensures that the teeth straightening process is continuous and effective.

Regular dental check-ups are also essential during Invisalign treatment. These visits allow the dentist to monitor progress, make necessary adjustments to the treatment plan, and provide guidance on aligner care. Adhering to these best practices will help patients achieve their desired results of straighter teeth and a new smile with minimal disruption to their daily lives.


In conclusion, Invisalign has proven to be an effective and innovative solution in orthodontic treatment. With its custom aligners, virtually invisible design, and advanced technology, Invisalign offers a comfortable and aesthetically pleasing alternative to traditional metal braces for teeth straightening. The effectiveness of Invisalign and its minimal impact on daily life make it an excellent choice for those seeking straighter teeth and improved oral health.
