Professional teeth whitening in Perth ranges from around $100 for a take-home kit to about $1,000 for premium in-chair treatment, depending on the method and the clinic. At Radiant Smiles our in-chair whitening starts from $490, with no hidden extras. This guide breaks down what every type of whitening costs, which option is cheapest, why prices vary, how the treatment actually works, and how to pay.
Teeth whitening prices at a glance
Here is how the main options compare on price and results. Our in-chair treatment sits below the typical Perth range because it is one fixed, all-inclusive fee.
| Whitening method | Typical cost | Results | How long it lasts |
|---|---|---|---|
| In-chair (professional) | $300 to $1,000 per session Radiant Smiles: $490 all-inclusive |
5 to 8 shades lighter | 6 months to 2 years |
| Take-home kit (custom trays) | $100 to $600 | 3 to 6 shades lighter | 4 to 6 months |
| Supermarket products | $3 to $60 | 1 to 3 shades lighter | 1 to 3 months |
Take-home vs in-chair whitening: which costs less?
If you are weighing the two professional options on price, here is the honest comparison.
Take-home custom kits have the lower upfront price, usually somewhere in the $100 to $600 range. You whiten at your own pace over one to two weeks, and the results last around 4 to 6 months before a top-up.
In-chair whitening costs more per visit, but at Radiant Smiles it is a flat $499 that includes everything, and the result is stronger and lasts far longer, from 6 months up to 2 years. Spread across how long it lasts, in-chair is often the better value, not just the faster option.
The cheapest professional route is a take-home kit. The best value over time is usually in-chair, because you are not buying gel and topping up as often. Many patients do both: an in-chair session to get the big lift, then a take-home kit to maintain it.
How Does Professional Teeth Whitening Actually Work?
Ever wondered how teeth whitening works? It’s not magic, it’s science. Your dentist puts a strong bleaching agent on your teeth (after protecting your gums) and this stuff gets into the tiny cracks in your enamel to break down all the gross stains from coffee, wine, and whatever else you’ve been enjoying.
The Science Behind Whitening
- The whitening gel breaks down into water and oxygen
- This oxygen gets into your teeth and busts up the stain molecules
- The chemical reaction breaks apart the stuff that makes your teeth look yellow
- Result: teeth look way whiter once those stains are gone
The Whitening Procedure
- We clean your teeth properly first
- We protect your gums so they don’t get irritated
- We apply the professional whitening gel to your teeth
- We shine a special light to make it work faster
- Someone qualified actually watches to make sure it’s working right
- We might do this a few times in one session for better results
- We rinse everything off and give you tips to manage any sensitivity
Does health insurance cover teeth whitening?
Most health funds treat whitening as a cosmetic treatment, so it is usually not rebated the way a filling or a clean is. Some extras policies offer a small benefit, so it is worth checking. As an HBF and NIB preferred provider we can look at your cover and claim any eligible rebate on the spot through HICAPS. If you would rather spread the cost, we offer payment plans through providers such as Afterpay, Zip and Humm, so you can whiten now and pay over time. See our payment plans page for details.
How long do whitening results last?
In-chair whitening usually lasts from 6 months up to 2 years, and a take-home kit around 4 to 6 months. How long you keep your results depends on your habits. Coffee, tea, red wine and smoking bring the stains back faster. A few simple steps after treatment keep your smile brighter for longer, see our guide on what to eat after teeth whitening. A take-home kit makes topping up easy when your shade starts to fade.
Are cheaper whitening options worth it?
Affordable whitening does not have to mean cheap supermarket kits. A $30 strip kit that fades in a month and needs buying again and again can cost more over a year than one professional treatment that lasts up to 2 years. Professional whitening is also safer, because a dentist checks your teeth first and protects your gums, and the result is far more even. If you want a genuinely affordable professional option, a custom take-home kit or our flat $499 in-chair price gives you a real result for a price you can plan around.

Teeth whitening cost FAQs
How much does professional teeth whitening cost in Perth?
In-chair whitening in Perth generally costs between $300 and $1,000 per session. At Radiant Smiles it is a flat $499, all-inclusive, with no separate consultation fee.
Is take-home or in-chair whitening cheaper?
A take-home custom kit has the lower upfront cost, usually $100 to $600. In-chair whitening costs more per visit, $499 at Radiant Smiles, but it lasts far longer, so it often works out the better value over time.
How much does a take-home whitening kit cost?
Take-home kits with custom trays generally range from $100 to $600 depending on the gel and the number of trays. Contact us for our current take-home price, or ask about pairing a kit with in-chair treatment.
Does teeth whitening damage enamel?
No. Professional whitening uses peroxide that lifts stains without harming the enamel itself. Some people feel short-term sensitivity, which is why we apply fluoride afterwards to settle it.
Is teeth whitening covered by my health fund?
Usually not, because whitening is considered cosmetic. Some extras policies pay a small benefit, so it is worth checking your cover. We can claim any eligible rebate for you through HICAPS as an HBF and NIB preferred provider.
Is professional whitening painful?
It should not be. The most common side effect is mild, short-lived sensitivity. The fluoride treatment at the end and using a sensitive toothpaste for a few days afterwards keeps it comfortable.
How white will my teeth get?
In-chair whitening typically lifts your teeth by 5 to 8 shades in one visit. Your exact result depends on your starting shade and the type of staining, which we assess at your check-up.
