Invisalign – Your Guide to a Straighter Smile


Table of Contents

When it comes to straightening teeth, many people face a choice between traditional braces and clear aligners. If you lean towards clear aligners, you’re not alone.

Clear aligners have significantly gained popularity over the past couple of decades as an effective alternative to traditional braces.

One of the oldest and most recognised clear aligner products is Invisalign, introduced in 1998 by Align Technology. Since then, several other brands have entered the market. 

This article delves into what Invisalign can do, its effectiveness, and the pros and cons associated with it.

What is Invisalign?

Invisalign is the brand name for a type of thin, clear aligner used in orthodontic treatment. The aligner is crafted from a flexible thermoplastic material called SmartTrack. This product is designed to make orthodontic treatment less noticeable compared to traditional braces.

Although Invisalign aligners are not entirely invisible, they fit tightly over your teeth and are much less noticeable than the brackets and wires of traditional braces.

What Dental Issues Can Invisalign Correct?

Invisalign is versatile and can address a variety of dental issues, including crowding and spacing issues, as well as some mild and moderate bite problems. The aligners can treat:

  • Crowding: Do you have teeth that seem to be overlapping or bunched together? Invisalign can effectively create space for proper alignment.
  • Spacing: Gaps between your teeth can be a source of self-consciousness. Invisalign can gently close those gaps for a more uniform smile.
  • Mild to Moderate Bite Problems: Invisalign can address some common bite issues like overbite, underbite, and crossbite.

It’s important to note that Invisalign might not be suitable for all cases, especially complex bite problems. A consultation with an orthodontist will help determine if Invisalign is the right choice for your specific needs.

What’s Involved with Wearing Invisalign?

The Invisalign journey starts with a visit to an orthodontist. They’ll use advanced technology to create a 3D image of your mouth and jaw. This digital blueprint allows them to develop a customised treatment plan specifically for your smile goals. Based on this plan, a series of clear, custom-made aligners are created. These comfortable, near-invisible aligners gently apply pressure to your teeth, gradually shifting them into their desired positions over time.

Typically, you’ll switch to a new aligner set every one to two weeks, following your orthodontist’s instructions. Consistent wear is key! Aim for 20-22 hours a day to ensure optimal results.

How Effective Are Invisalign Aligners?

While many people achieve fantastic results with Invisalign, it’s important to manage expectations. Research is ongoing, but some factors can influence the treatment’s effectiveness.

However, some research suggests that Invisalign is more effective than other types of clear aligners. The newer versions of Invisalign, produced after 2010, have improved the delivery of force on the teeth, enhancing their effectiveness.

Factors Affecting Invisalign’s Effectiveness

For Invisalign to work effectively, wearing the aligners for 20 to 22 hours daily is crucial. The only times you should remove the aligners are when you are eating or drinking, brushing or flossing your teeth, or cleaning your aligners.

  • Compliance: Dedication is key. The more consistently you wear your aligners, the faster you’ll see progress.
  • Complexity of Case: Invisalign is most effective for mild to moderate cases of crowding, spacing, and some bite issues. More complex misalignments may require alternative treatment options.
  • Age and Sex: Studies suggest that tooth movement might be slightly more efficient between ages 35-50 and that women may experience less decline in tooth movement effectiveness as they age compared to men. However, these are general trends, and individual results may vary.

When cleaning your aligners, avoid using very hot water as it can warp the plastic, altering the fit and potentially affecting the treatment’s progress and effectiveness.

The complexity of your orthodontic issues also plays a role in how well Invisalign works for you. More complex spacing or bite issues may require longer treatment times.

Detailed Comparison with Traditional Braces

Maintenance Easy to brush and floss, aligners need regular cleaning Brushing and flossing around brackets and wires is challenging

Treatment Duration Similar to or shorter than braces, varies by case Typically 18 months to 3 years, depending on severity
Effectiveness Best for mild to moderate dental issues Effective for all dental issues, including severe misalignments

Is Invisalign Right for You?

Consider these questions to determine if Invisalign is a suitable choice:

  • Do you have straightforward crowding or bite issues?
  • Do you prefer a less visible treatment option than braces?
  • Can you commit to wearing the aligners for the required hours each day?
  • Can you afford the treatment?
  • Will you care for the aligners properly?

For teenagers considering Invisalign, assess their likelihood to wear and maintain the aligners. If they are prone to losing things, traditional braces might be a better option.


Invisalign can address various dental issues, including crowding, spacing, and mild to moderate bite issues. It may be a good option if you prefer a less conspicuous treatment than braces and have uncomplicated dental problems.

Discuss your dental needs with our orthodontist or dentist to determine if Invisalign is the right choice for you. Carefully weigh the pros and cons before making your decision.
