How do clear aligners work?

Clear aligners are a series of custom-made, removable plastic trays that gradually move teeth into their correct positions. Each tray in the series is slightly different from the last, applying gentle, controlled force to specific teeth. Patients wear each set of trays for approximately one to two weeks before progressing to the next set. Treatment is planned digitally before it begins, allowing Dr Carolyn to map out tooth movements from start to finish.

Invisalign & Aligners in Hawthorn

Aligners represent a modern approach to orthodontic treatment, offering a clear and comfortable alternative to traditional braces.

Custom-made to fit your unique dental anatomy, aligners gently apply controlled pressure to gradually move your teeth into their desired positions.

With options like Invisalign, Angel Align, and Spark Aligners, patients can embark on their journey to a confident smile with minimal interruption to their daily lives.

Why Choose Clear Aligners?

Clear aligners are a clear, flexible plastic material that fits snugly over the teeth, gradually applying gentle pressure to shift them into the desired position.

Discreet appearance: Clear aligners are nearly invisible when worn, making them a popular choice for adults and teens.

Removable: Aligners can be taken out for eating, drinking, brushing, and flossing, allowing for greater flexibility and convenience.

Comfort: Aligners are typically more comfortable than traditional braces, as they do not have metal brackets or wires that can irritate the mouth.

Easy maintenance: Cleaning clear aligners is simple with the use of special cleaning solutions or even just water and a toothbrush.

The best time to start aligner treatment varies depending on individual circumstances, but it is generally recommended to begin once most or all of the permanent teeth have erupted.

This typically occurs in the early teenage years, but aligner treatment can be started at any age once the teeth and jaws are fully developed.

Clear aligners are suitable for many patients seeking orthodontic treatment, including adults and teens with mild to moderate crowding, spacing, or bite issues.

However, they may not be suitable for everyone, particularly those with more complex orthodontic problems or certain dental conditions.

Frequently Asked Questions About Clear Aligners

Clear aligners are a series of custom-made, removable trays fabricated from clear flexible plastic. Each tray applies gentle, controlled pressure to specific teeth, moving them incrementally toward their target positions. You progress through a series of trays — typically changing to a new set every one to two weeks — with each tray bringing your teeth slightly closer to the final result. Treatment is planned digitally by Dr Carolyn using 3D scanning technology before any trays are made.

Aligners need to be worn for at least 22 hours per day to be effective. They should only be removed for eating, drinking anything other than water, brushing and flossing. Insufficient wear time is the most common reason aligner treatment takes longer than planned or produces less than optimal results. Consistency is essential.

For many cases, yes. Clear aligners are highly effective for mild to moderate crowding, spacing and certain bite issues. However, for complex orthodontic problems — particularly those requiring significant rotation, vertical tooth movements or jaw correction — fixed braces often provide more precise control. Dr Carolyn will assess your case and recommend the most clinically appropriate option for your specific needs.

Invisalign is the most established and widely researched clear aligner system, with a long clinical track record. Angel Align and other brands use similar technology — custom-fabricated plastic trays planned digitally — but may differ in material composition, tray thickness and the software used for treatment planning. Dr Carolyn works with multiple aligner systems and will recommend the most appropriate option based on your clinical needs and treatment goals.

Yes — because aligners are removable, you can eat and drink whatever you like. Simply remove your aligners before meals and drinks other than plain water, then brush your teeth before reinserting them. This is one of the most significant lifestyle advantages of aligners over fixed braces, as there are no food restrictions.

Yes. While clear aligners are available through various channels, including direct-to-consumer services, specialist orthodontists have completed additional years of university training beyond dental school specifically in tooth movement and bite correction. This expertise ensures your treatment is planned accurately, monitored at regular appointments, and completed safely. Dr Carolyn provides face-to-face specialist aligner care at her Hawthorn practice.
