Two clinics can quote very different figures for Invisalign and both be fair, because they are often pricing different things. Across the Sydney market, adult treatment commonly falls somewhere between about $4,500 and $9,000. Where your own case lands depends mostly on how far your teeth need to move and on what the quote actually covers.
The useful question is less "what does Invisalign cost" and more "what am I paying for, and is there a different way to reach the same result". This article works through both, and also explains the other clinician-supervised aligner systems we prescribe, which can suit some cases at a lower total fee. The figures here are general market ranges, not a quote.
The size of the tooth movement sets most of the fee
Invisalign is charged as a course of treatment rather than per tray. Align Technology, the company that makes it, charges the clinic a laboratory fee that rises with the amount of planned movement and the product prescribed. That laboratory fee is a large part of what you pay.
A small correction, such as tidying a few crowded lower front teeth, may need only a short series of aligners over a handful of months. Crowding that runs across the whole arch usually takes longer. Cases involving a deep bite, open bite or crossbite usually take longer again and often include extra refinement stages near the end. Each step up in complexity usually means more aligners, more planning time and more appointments.
Align offers several product levels to match this, from limited packages with a capped number of aligners for minor cases through to products that allow additional aligners across a longer treatment window. A teen version exists for younger patients whose teeth are still coming through. The product your dentist recommends follows from the clinical assessment, not the other way round.
Two quotes are only comparable if they include the same things
A lower headline fee is sometimes lower because items have been left out. When comparing, check whether each quote includes:
- the examination, X-rays, photographs and digital scan
- the digital treatment plan and simulation
- every aligner in the planned series
- attachments, the small tooth-coloured bumps bonded to some teeth so the aligners can grip
- all review visits during treatment
- refinement aligners if the teeth need fine-tuning at the end
- retainers once the teeth are in position
Retainers and refinements are the two items most often charged separately. A quote that excludes them can end up costing more than one that looked higher at first.
It is also fair to ask what happens if an aligner is lost or broken partway through. Our article on a lost or damaged aligner tray explains what usually happens next and why it matters to keep your previous set.
Invisalign is one of three systems we prescribe
At Lumi Dental we prescribe Invisalign, Spark Aligners (made by Ormco) and Angel Aligners (made by Angelalign). All three are planned from a digital scan, worn the same way and reviewed in person by your dentist. The main differences are the manufacturer, the aligner material, the range of cases each is designed for, and the laboratory fee charged to the clinic.
Invisalign has the longest clinical track record of the three and is used for the widest range of case types, including some harder bite corrections. It also carries the highest laboratory fee. Spark and Angel are used for many mild to moderate adult cases and are often a lower total fee for that reason alone, with the same chairside supervision.
For some cases the extra range of Invisalign is clinically useful. For many straightforward cases, any of the three may reach the planned movement. Which one makes sense is decided with you at the consultation, once your scan and X-rays have been reviewed. If you want a closer look at the differences, we have a separate comparison of clear aligners and Invisalign.
Aligners posted to your home are a different product
Direct-to-consumer aligner companies send trays by mail with limited or no in-person examination. They are often cheaper, but the price leaves out the parts of treatment that protect your teeth: checking for decay and gum disease before teeth are moved, X-rays of the roots and bone, and someone examining your bite as it changes. The Australian Dental Association has raised concerns about this model. It is a poor fit for anyone with gum problems, missing teeth or a bite that needs correcting.
What happens between the scan and the retainer
Treatment starts with an examination of your teeth, gums and bite. Clear aligners are not suitable for everyone. Untreated gum disease, active decay, significant bone loss or a bite problem rooted in the jaws may need to be addressed first, or may point to a different approach, sometimes including referral to a registered specialist orthodontist.
If aligners suit your case, we take a 3D scan with an intraoral scanner along with photographs and X-rays. From these a digital plan is built that shows how each tooth is planned to move and roughly how many aligners will be needed. You see this plan before you commit.
When the aligners arrive, any attachments are bonded and the first set is fitted. Aligners are generally worn for 20 to 22 hours a day and taken out only to eat, to drink anything other than plain water, and to clean your teeth. Each set is usually worn for one to two weeks. Review visits are spaced through treatment so your dentist can check that the teeth are tracking as planned.
At the end of the series, the result is checked against the plan. If some teeth have not fully reached position, a short set of refinement aligners is made. Whether refinements are included in the original fee depends on the system and package, so ask about this at the start.
Retainers are part of the cost, for good
Teeth tend to drift after any orthodontic treatment, so retainers are a long-term commitment rather than an optional extra. Options include clear removable retainers and a thin fixed wire bonded behind the front teeth. Removable retainers wear out over time and need replacing, and a fixed wire needs checking at your regular visits. It is worth factoring this ongoing cost into your thinking, whichever system you choose.
Health funds and spreading the payments
Medicare does not cover Invisalign or other orthodontic treatment for adults, and the Child Dental Benefits Schedule does not cover orthodontics either. Private health insurance with extras cover that includes orthodontics may contribute. The amount varies widely by fund and level of cover, and most funds apply a waiting period for orthodontics, commonly 12 months, along with annual or lifetime limits. Many funds treat braces and clear aligners under the same orthodontic category, so check your orthodontic limit rather than your general dental limit.
Many clinics split the fee into an initial payment and staged payments through treatment. Current offers and payment arrangements are listed on our current deals page.

Questions worth asking before you sign
Which aligner systems are available, and how do their fees compare for my case?
A clinic that prescribes more than one system can show you the difference for your teeth specifically. If only one system is offered, ask whether a lower-fee option could reach a similar result.
Who will supervise my treatment?
Clear aligners may be provided by a general dentist with aligner training or by a registered specialist orthodontist. Ask who plans the case, who sees you at reviews, and what happens if teeth do not track as planned.
Is Invisalign worth the higher fee?
It can be, for cases where its wider range of movements is clinically useful. Fixed braces remain more predictable for some complex movements, and for many routine cases another supervised aligner system may achieve a similar goal at a lower fee. An examination is the only reliable way to know which applies to you.
Getting a written treatment plan
A consultation lets us examine your teeth, take a scan if appropriate, and explain what is included for each suitable system. You will usually receive a written treatment plan, often by email. Free consults are offered for aligner treatment, and you can read more about clear aligners at Lumi Dental or book an aligner consultation at our Melrose Park practice inside Melrose Central. If you are nervous about dental visits, ask us about sedation options.
