Bringing Out the Very Best in
Your Smile

Invisalign®

For more than two decades, Invisalign has proved to be an effective orthodontic treatment to straighten teeth and correct bite irregularities for many adults and teenagers. As an innovative alternative to traditional braces, Invisalign trays are custom-made, clear, flexible plastic aligners that go virtually unnoticed. Our experienced cosmetic dentist in Markham, Dr. Susie Ang, is pleased to offer Invisalign to help improve signs of common orthodontic concerns and create a beautifully renewed smile.

What Are the Benefits of Invisalign?

Invisalign offers a revolutionary way to correct mild to moderate orthodontic concerns without the self-consciousness associated with wearing noticeable metal braces. Patients all over the world have found success with Invisalign and its many benefits. The advantages offered by Invisalign include:

Enhanced Comfort – Invisalign can adjust misaligned teeth, diminish gaps and spaces, and address bite irregularities without the need for the metal brackets and wires used in traditional braces.

Virtually Invisible Oral Appliances – The aligners that are placed on the teeth are practically undetectable since they are made of a translucent plastic material.  

Removable Aligners – Day-to-day activities like eating, drinking, brushing, and flossing are easier because you can remove the aligners at any time. Note: it is recommended to leave your aligners in as much as possible to maximize results.

More Easily Maintainable – Invisalign simplifies the upkeep process as the aligners don’t require as many office visits or the same kind of adjustments compared to other orthodontic treatments.

Invisalign can also achieve results rather quickly when a proper treatment schedule is followed. Depending on personal needs and goals, many patients have experienced optimal outcomes in 6 – 15 months. 

Am I a Candidate for Invisalign?

Not every orthodontic concern responds the same way to clear aligner therapy, which is why a hands-on evaluation matters more than a quick online quiz. Good candidates typically have healthy gums, adequate bone support, and orthodontic concerns such as crowded or gapped teeth or a mild-to-moderate bite misalignment that fall within the range aligners are designed to correct. Teens and adults are both commonly treated with Invisalign, provided that permanent teeth have fully come in.

Some situations require an even closer look before Invisalign can be recommended, including significant tooth rotation, large gaps, or bite discrepancies that may respond better to a different orthodontic approach. During a consultation, Dr. Ang examines the teeth, jaw, and bite, and reviews any relevant imaging to determine whether clear aligners are a realistic path to the results you’re hoping for, or whether another option would serve you better.

Invisalign vs. Braces

Invisalign and traditional braces are both solutions to help patients achieve straighter teeth and improve bite issues. However, traditional braces use brackets and wires, which are more prominently seen and felt throughout your mouth. Invisalign revolutionized an alternative approach by using clear, flexible plastic aligners (trays) that go over the teeth. This design and material make the aligners almost invisible, and often much more comfortable. The aligners are easily removed for mealtime, so you don’t need to worry about food getting stuck, and they are simple to clean.

Each patient has unique needs so it’s important to understand that Invisalign® can often be effective for mild to moderate orthodontic concerns, but more severe conditions may require traditional braces or another orthodontic treatment. Dr. Ang can determine upon evaluation whether Invisalign or an alternative option, such as ALF Lightwire Orthodontics or another type of treatment, will be best for your needs.

What Does the Invisalign Treatment Process Involve?


During your initial consultation, your teeth and bite will be examined to determine if you are an ideal Invisalign candidate. If you decide to move forward with the treatment, here is a general overview of the process:

  • An impression of your teeth will be created to design your first set of custom aligners, along with a series of additional aligners (usually 18 – 30 sets) each modified to gradually move the teeth into an improved alignment.
  • Each set of aligners will be worn for approximately two weeks before moving on to the next set.
  • It is recommended to wear your aligners for 20 – 22 hours per day, other than when you are eating, drinking, or cleaning your teeth.
  • Once your treatment is complete, you may receive a retainer to wear to help maintain the new and improved position of your teeth. After a certain amount of time, many patients only need to wear the retainer while sleeping

Does Invisalign Hurt?

Because Invisalign relies on smooth plastic aligners rather than metal brackets and wires, it tends to be far gentler on the cheeks, lips, and gums than traditional braces. That said, moving teeth is still an active process, and it’s normal to notice pressure or mild tenderness for the first day or two after switching to a new aligner in the series. This sensation is generally a sign that the aligner is doing its job, and most patients find it subsides quickly as the mouth adjusts.

How Much Does Invisalign Cost?

Because every smile is different, the cost of Invisalign treatment varies based on factors like the complexity of the case, the number of aligners required, and the estimated length of treatment. Straightforward corrections generally involve a shorter aligner series and a lower overall investment, while more involved bite or spacing issues may require a longer, more comprehensive plan.

The most accurate way to understand what Invisalign would cost for your specific smile is through a consultation with Dr. Ang, where your teeth and bite are assessed in person and a personalized treatment plan and estimate can be provided. Many dental insurance plans offer partial coverage for orthodontic treatment, and our team is happy to help you explore your options.
