9 Invisalign Faq’s – Your Questions About Invisalign Answered

If you are considering Invisalign in Melbourne, you probably have questions about how the treatment works, how comfortable it is, and what to expect. Invisalign is one of the most widely used clear aligner systems worldwide, and at The Smile Designer Dental Studio in Preston, we are a Platinum Invisalign Provider, a status held for five consecutive years, reflecting the number of Invisalign cases treated by our team over that time.

This page brings together the questions patients most commonly ask before, during, and after Invisalign treatment – covering the aligner material itself, comfort, treatment length, retainers, drinking and eating with aligners in, cost, the digital planning process, cleaning, and whitening alongside treatment. Whether you’re just starting to research clear aligners or you’re comparing Invisalign against traditional braces, this guide is intended to give you a clear, factual starting point before your consultation.

What are the aligners made from?

Invisalign aligners are made using SmartTrack® material, a multi-layered, elastic material developed through Invisalign’s own research and development process. This material is designed to provide a precise fit and consistent, gentle pressure throughout treatment. Unlike some earlier generations of clear aligner material, SmartTrack is designed to fit more closely to the tooth surface, which is intended to support more predictable tooth movement across each stage of your treatment plan.

Each aligner is manufactured individually based on a digital 3D model of your teeth, created from a scan taken at The Smile Designer using an iTero digital scanner. Because each aligner in your series is slightly different from the one before it, the material needs to be both rigid enough to apply directional pressure and flexible enough to be inserted and removed comfortably.

Will the aligners be painful?

Some discomfort is normal whenever teeth are moving, which is a normal part of any orthodontic treatment – whether that’s Invisalign, traditional braces, or another aligner system. Invisalign aligners are designed to fit closely to your teeth, which can help reduce irritation from rubbing or rough edges. As with any orthodontic treatment, individual experience varies, and some patients may experience more discomfort than others, particularly for the first day or two after changing to a new aligner in the series.

Many patients describe the sensation as pressure or tightness rather than sharp pain, and this typically settles within a day or two as your teeth and gums adjust to each new aligner. If you experience persistent or worsening discomfort, or notice any sharp edges on your aligners, contact The Smile Designer Dental Studio so we can assess whether an adjustment is needed.

How fast is the treatment?

Treatment speed depends on your individual case, which is assessed during a consultation and confirmed through your digital ClinCheck treatment plan. Aligners are typically changed every one to two weeks, depending on your treatment plan and how your teeth are responding. Straightforward cases – often involving mild crowding or spacing – may be completed in as little as six months using an Express treatment plan. More complex cases, which might involve bite correction, more significant crowding, or rotated teeth, may take twelve to eighteen months or longer.

Your dentist will provide an estimated timeframe as part of your personalised treatment plan, based on your digital scan and the specific movements required. It’s worth noting that the estimated timeframe shown in your initial ClinCheck simulation is a projection based on how teeth typically respond – actual treatment time can vary if additional aligners or a refinement stage are needed. You can read more about how refinements work on our dedicated Invisalign refinements guide.

How long do I have to wear my retainer?

After completing Invisalign treatment, a retainer is required to help maintain tooth position. Teeth have a natural tendency to shift over time, so retention is considered a standard, ongoing part of any orthodontic treatment, not an optional add-on.

Some patients are advised to wear retainers full-time for a period after treatment, gradually reducing to night-time-only wear. Others may move to a night-time schedule sooner, depending on their case. Your dentist at The Smile Designer Dental Studio in Preston will recommend a retainer schedule based on your individual case, and will review this at your post-treatment appointments.

Can I drink coffee while wearing my aligners?

Hot beverages like coffee and tea can stain or warp aligners, and sugary drinks, soft drinks, or wine can contribute to plaque build-up underneath the aligners if left in place while drinking. Water is the only beverage recommended while wearing your aligners – for anything else, it’s best to remove them, drink, and then clean your teeth before reinserting.

This is one of the more commonly underestimated parts of aligner treatment. Many patients find the “remove before eating or drinking” rule straightforward for meals but forget it applies to casual drinks throughout the day too. Getting into a consistent habit early in treatment tends to make this easier to manage.

How much does Invisalign cost?

The cost of Invisalign depends on the complexity of your case and the number of aligners required. As a general guide:

• Express treatment (10-14 aligners): approximately $3,500-$4,000
• Complex treatment (12-18+ months of aligners): approximately $9,500-$10,000

At The Smile Designer Dental Studio in Preston, treatment plans are assessed and quoted individually following a consultation and digital scan, and flexible payment options are available, including 12-month interest-free plans. For a full cost breakdown across all orthodontic options, see our Braces Cost Melbourne guide.

How are the aligners made?

Invisalign uses 3D imaging technology to map your teeth and create a custom treatment plan, known as a ClinCheck. Your dentist reviews this digital simulation with you before treatment begins, so you have an idea of the intended movement of your teeth at each stage. Each aligner in the series is slightly different, applying gentle, incremental pressure to move teeth toward their planned position.

Unlike traditional braces, which are adjusted in-chair at each visit, Invisalign check-in visits are typically shorter and scheduled roughly every six weeks to review progress and issue your next set of aligners. Some patients also require small, tooth-coloured attachments – bonded to specific teeth to help the aligners grip and apply more targeted pressure for certain movements. Whether attachments are needed depends on your individual treatment plan and is confirmed by your dentist.

How do I clean my aligners?

Cleaning your aligners regularly helps reduce the risk of staining, odour, and decay. The general steps are:

• Remove your aligners before eating or drinking anything other than water.
• Rinse your aligners with lukewarm water each time you remove them.
• Brush your aligners gently morning and night, using a soft toothbrush – avoid using toothpaste directly on the aligners, as some formulas can be abrasive.
• Avoid hot water, which can warp the aligner material and affect fit.
• Store your aligners in their case whenever they’re not being worn.

Brushing and flossing your own teeth before reinserting your aligners is also an important part of the routine, since anything trapped between your teeth and the aligner stays in close contact with your enamel for extended periods throughout the day.

Can I whiten my teeth during Invisalign treatment?

Teeth whitening can be considered alongside Invisalign treatment, though it’s often recommended to wait until after treatment is completed to reduce the risk of sensitivity, and to ensure the whitening result is even across all teeth once they’re in their final position. The Smile Designer Dental Studio offers both in-chair whitening and take-home whitening kits, and your dentist can advise on the best timing during your consultation or review appointments.

What age can I start Invisalign treatment?

Invisalign is suitable for a wide age range, from teens to older adults. Suitability depends on individual dental development and commitment to wearing aligners as directed – typically around 20-22 hours per day – and is confirmed during a consultation. For younger patients still undergoing dental development, additional assessment may be needed to determine the most appropriate timing and treatment type.

Can Invisalign treat complex bite issues?

Invisalign can be effective for concerns including gaps, spacing, mild to moderate crowding, and mild overbites, underbites, or crossbites. More significant bite issues, such as severe overbites or complex jaw discrepancies, may require alternative treatment approaches, determined following a clinical assessment. If you’re unsure whether your case is suited to Invisalign, our Invisalign vs Braces guide covers how suitability is typically assessed.

Will I need attachments on my teeth during treatment?

Some patients require small, tooth-coloured attachments to help the aligners grip and move certain teeth more effectively – particularly for movements like rotation or extrusion that are harder for a smooth aligner surface to achieve on its own. Whether attachments are needed depends on your individual treatment plan, and they are generally removed once treatment is complete.

What happens after my Invisalign treatment finishes?

Once active treatment is complete, retainers are provided to help support your teeth in their new position. Regular dental check-ups and good oral hygiene help maintain results over time. Some patients also choose to explore further cosmetic treatment once their teeth are aligned – for example, teeth whitening or addressing any remaining concerns about tooth shape with composite bonding – though this is entirely optional and depends on individual goals.
