A box of whitening strips from the pharmacy and a course of whitening from a dentist can differ in price by several hundred dollars, and most of that gap comes down to gel strength, fit and supervision. Dentist take-home whitening with custom trays typically costs $300 to $700 in Australia, while an in-chair session costs more again. The figures below are general market ranges, not Lumi Dental's fees.
This guide sets out where each option usually sits on price, what you are paying for at each level, and the extra costs that are easy to leave out of the sums.
Prices rise with gel strength and supervision
| Option | Typical market range | What the price usually covers |
|---|---|---|
| Over-the-counter kits and strips | About $20 to $150 | Low-strength gel, one-size trays or strips, no dental check |
| Take-home whitening from a dentist | $300 to $700 | A dental examination, trays made to fit your teeth, and professional-strength gel |
| In-chair whitening | About $600 to $1,000 or more | A supervised session with high-strength gel and the gums protected; some practices include take-home trays, others charge for them separately |
The over-the-counter and in-chair ranges come from iSelect's teeth whitening cost guide. The take-home range is a typical market figure for dentist-supplied trays and gel. Fees in any one city vary between practices, so treat all three as a starting point for comparison rather than a quote.
Stronger gels can only come from a dental practitioner
Under Schedule 10 of the Poisons Standard, as summarised in the Australian Dental Association's teeth whitening policy, products containing more than 6% hydrogen peroxide or more than 18% carbamide peroxide may only be sold, supplied and used by registered dental practitioners. Anything you can buy off the shelf sits below those limits, which is one reason it tends to work more slowly.
The higher price of professional whitening also pays for things a kit cannot do. A dentist or OHT looks for decay, cracks, receding gums and old fillings first, because gel on an exposed root or a leaking filling can be very uncomfortable, and tooth-coloured fillings will not lighten at all. Trays made from a scan hold the gel evenly against each tooth and keep it off the gums, while generic strips and trays often miss the edges and the teeth further back. Our article on how custom whitening trays work covers how they are made.

A cheaper in-chair price may leave out the take-home phase
Some of the brightness seen straight after an in-chair session is temporary. Teeth lose a little water while the gel and cheek retractors are in place, and as they rehydrate over the following days, part of that colour settles back. Take-home gel worn in trays is what continues the lightening and holds it, which is why we pair in-chair whitening with take-home trays rather than offering it alone. Our article on why in-chair whitening alone does not get you all the way explains this in more detail.
So when one in-chair quote looks noticeably lower than another, check whether trays and gel are part of it. A session on its own and a session with a take-home course are different products.
Paying for a light or laser does not usually buy a better result either. A systematic review by Maran and colleagues (Journal of Dentistry, 2018) pooled 21 randomised trials and found that adding light to in-office bleaching did not appear to improve colour change or change tooth sensitivity. Our article on LED light whitening goes further into the evidence.
Extra costs that can sit outside the whitening fee
A check-up and clean beforehand
If your last visit was more than about six months ago, a check-up and clean usually comes first. In Sydney that commonly costs $200 to $400, depending on whether X-rays are needed. Removing plaque and surface stain helps the gel act evenly, and some people find a clean alone lifts the colour more than they expected. A general check-up and clean covers this step.
Treatment for anything the check finds
Decay, cracked teeth and inflamed gums are dealt with before whitening, not after. That cost depends entirely on what is found, and many people need nothing at all.
Fillings or bonding that no longer match
Fillings, crowns, veneers and bonding keep their colour while natural teeth lighten. A visible filling on a front tooth may need replacing afterwards so it blends in, and composite bonding typically costs $250 to $800 per tooth as a market range. Our guide to whitening with fillings or bonding explains how this is usually planned, and composite bonding is the usual way to rematch a front tooth.
Top-up gel and replacement trays
Once you have your own trays, keeping the colour usually means buying more gel every so often rather than starting again. A new crown or filling can change how a tray fits, in which case a replacement set is made from a fresh scan.
Questions that make quotes easier to compare
- Is a take-home course included after any in-chair session?
- Are the trays made from a scan or impression of my teeth?
- Who examines my teeth first, and are X-rays included if needed?
- What is the plan if my teeth become sensitive?
- Is there a review once the colour has settled?
Be wary of any offer that promises a set number of shades or a particular final shade. How far teeth lighten depends on their starting colour, the type of staining and how consistently the trays are worn. Our guide to how many shades whiter teeth can go explains what drives the difference.
Whitening options and current fees at Lumi
Lumi Dental has three whitening options. Lumi Home is take-home Boutique whitening with custom trays, offered as an overnight gel for sensitive teeth or a daytime gel for teeth that are not sensitive. Lumi Refresh and Lumi Radiance add in-chair whitening and also include Boutique take-home whitening. Our comparison of Lumi Home, Refresh and Radiance explains who each one tends to suit. We never promise a particular shade.
We do not list fees in our articles. Current pricing is on the teeth whitening page and the current deals page, and our teeth whitening in Sydney page gives an overview for people coming from further away. A free cosmetic consult includes a check of whether whitening suits your teeth, and you will usually receive a written treatment plan, often by email, before anything goes ahead.
Common questions about whitening costs
Does private health insurance pay for whitening?
Usually not, because most funds treat it as cosmetic. The examination and clean beforehand may be claimable on extras cover, depending on your policy. Our article on whether health insurance covers teeth whitening lists what to ask your fund.
How often will I need to pay for whitening again?
Our usual guidance is that results last about two to three years before a top-up is needed to keep the same level, and keeping your trays means a top-up is mostly the cost of gel. Coffee, tea, red wine, smoking and vaping tend to shorten that time.
Is a salon or kiosk a cheaper way to get the same result?
Salons and kiosks cannot use gels above the Schedule 10 limits, and nobody examines your teeth before the gel goes on. They may cost less per visit, but the product is closer to a pharmacy kit than to dentist whitening.
