Wondering what actually happens when you get teeth whitening at Alexandra Hills Dental? Here’s the short answer: it’s a professional Pola whitening system, either done in the chair or taken home in a custom tray, and it’s built to lighten your smile safely under a dentist’s supervision. If you’ve been putting off whitening because you’re worried it’ll hurt, or you’re not sure the results are worth it, you’re not alone. A lot of our patients come in feeling exactly the same way, usually after noticing their teeth looking a bit more yellow or stained right before a wedding, a work event, or just a big birthday coming up.
Why Teeth Naturally Yellow or Stain Over Time
Teeth don’t stay bright white forever, and that’s completely normal. The outer layer of enamel wears thin with age, which lets more of the naturally yellow dentine underneath show through. On top of that, everyday habits play a role: coffee, tea, red wine, and curry all contain pigments that settle into the tiny pores in your enamel. Smoking speeds up staining too.
| Cause | Why it stains your teeth |
|---|---|
| Ageing enamel | Enamel thins over time, letting more of the naturally yellow dentine underneath show through. |
| Coffee, tea and red wine | Pigments in these drinks settle into the tiny pores in your enamel with regular use. |
| Smoking or tobacco use | Speeds up staining and tends to cause deeper, harder-to-shift discolouration. |
| Certain childhood medications | Some medications can affect how enamel and dentine develop, leading to staining later in life. |
| Skipping regular scale and clean | Surface plaque and calculus build up and dull the natural shade of your teeth. |
None of this means you’ve done anything wrong. It’s just biology and lifestyle catching up with your smile, and whitening is one of the most straightforward ways to turn the clock back a bit.
What Professional Pola Whitening Involves
At our Alexandra Hills clinic, we use the Pola whitening system, which comes in two main forms: Pola Day and Pola Night. Both use a bleaching gel applied through a custom-fitted tray that’s moulded to your teeth, so the gel sits evenly across your smile instead of pooling in one spot the way a generic strip or shop-bought kit might.
The strength of the gel is the big difference between professional and at-home whitening. Done under our supervision, the treatment uses a solution with roughly 35 percent more hydrogen peroxide than you’d find in a shop-bought kit, which is why it’s only ever provided with a dentist’s guidance rather than sold over the counter. The take-home formulation we dispense contains 18 percent carbamide peroxide, again only available through professional guidance, not off a supermarket shelf.
In-Chair Whitening Versus Take-Home Whitening Kits

Patients often ask which option is best, and honestly, it depends on your lifestyle and how quickly you want results.
| Feature | In-chair whitening | Take-home kit |
|---|---|---|
| Where it happens | At our Alexandra Hills clinic | At home, using your custom tray |
| Supervision | Supervised the whole time, in the chair | Dentist-prescribed and reviewed, self-applied at home |
| Time to see results | Faster, noticeably whiter after a single appointment | Gradual, over 14 consecutive days or nights |
| Session length | One appointment | One to two hours per session, depending on gel concentration |
| Best suited to | Patients who want a fast result before an event | Patients who prefer to whiten gradually in their own time |
Both are professional, dentist-supervised options. Neither is the bargain-bin whitening strip you’ll find at the chemist, and that’s exactly the point.
How Long Teeth Whitening Results Actually Last
Whitening isn’t permanent. Most patients enjoy their brighter smile for around six months to two years, depending on diet, smoking habits, and how well they maintain their oral hygiene afterwards. If you’re a big coffee or red wine drinker, expect the effect to fade a bit sooner. A touch-up treatment every so often keeps things topped up, and your custom tray can be reused for future top-ups if you’ve gone the take-home route.

Is Teeth Whitening Safe For Sensitive Teeth
This is probably the question we get asked most, and it’s a fair one. Whitening can cause temporary sensitivity to hot or cold, particularly in the first few days. It’s usually mild and settles on its own. If you already have sensitive teeth, gum recession, or exposed roots, we’ll talk through this at your consultation and may recommend a lower-strength gel or a desensitising step first. The key word here is supervised: because a dentist is involved from the start, we can adjust the approach so it stays comfortable rather than guessing with an off-the-shelf product.
Common Whitening Mistakes That Damage Enamel
A few things we see go wrong when people try to shortcut the process:
- Overusing whitening strips or gels bought online without any guidance on strength or duration
- Skipping a scale and clean beforehand, so the gel works against a layer of plaque instead of clean enamel
- Whitening over existing crowns, veneers, or fillings, expecting them to lighten too (they won’t, since porcelain and composite don’t respond to bleaching gel)
- Leaving a take-home tray on for far longer than instructed, thinking more time equals better results
Whitening is safe when it’s done properly, but rushing it or using unsupervised products is the fastest way to end up with sore gums and patchy results instead of a brighter smile.
What A Scale and Clean Does Before Whitening

We recommend a check-up and clean before any whitening treatment, and there’s a good reason for it beyond just general oral health. A clean removes surface plaque and calculus, giving the whitening gel a clear path to the enamel rather than working through built-up residue. It also gives us a chance to check for cavities, gum issues, or anything else that whitening gel could aggravate. Our first-time check-up and clean is $190, regardless of your health fund status, so there’s no surprise pricing hidden behind the appointment.
Teeth Whitening Cost and Payment Plan Options
We’re upfront about cost because we know it’s usually the first question on your mind, right after “will this hurt?” Whitening treatment costs vary depending on whether you choose in-chair or take-home, and we’ll give you an exact quote at your consultation rather than a vague ballpark.
| Whitening method | Typical Australian market range | Notes |
|---|---|---|
| Over-the-counter strips or kits | Roughly $10–$70 | Not dentist-supervised, generally milder results |
| Dentist-prescribed take-home kit | Roughly $250–$600 | Custom tray, professional-strength gel, used over about 14 days |
| In-chair professional whitening | Roughly $400–$1,200+ | Single supervised appointment, stronger gel, fastest result |
Ranges reflect general Australian industry pricing reported across multiple dental providers and will vary by clinic, gel strength and individual treatment needs. Ask us for a personalised quote at your consultation.
To make treatment more accessible, we offer three payment plan options plus SuperCare, so cosmetic treatment doesn’t have to be paid upfront in one go. We’re also a preferred provider for CBHS, Australian Unity, HCF, Medibank and Bupa, which can reduce your out-of-pocket cost if your fund covers cosmetic or general treatment.

Who Should Avoid Teeth Whitening Or Get Advice First
Whitening isn’t right for everyone straight away. You should chat with us first if:
- You’re pregnant or breastfeeding
- You have untreated cavities or gum disease
- You have crowns, veneers, or visible fillings on front teeth (these won’t whiten and may end up a different shade to your natural teeth)
- You already experience significant tooth sensitivity
None of these rule out whitening forever; they just mean we’ll want to sort out the underlying issue first, or talk through realistic expectations for a mixed smile with existing dental work.
What To Expect At Your Whitening Consultation
Your first visit is really just a conversation, not a commitment to treatment on the spot. We’ll check your teeth and gums, talk about what’s causing any staining, and go through in-chair versus take-home so you can pick what fits your life. If you decide to go ahead, we’ll take an impression for your custom tray (for take-home whitening) or book you in for an in-chair session. We keep things calm and judgement-free the whole way through, however long it’s been since your last dental visit.

Maintaining A Brighter Smile After Treatment

Keeping your results bright is mostly about small daily habits. Cut back on coffee, tea, red wine, and smoking where you can, or at least rinse with water afterwards. Keep up regular brushing and flossing, and book a scale and clean every six months. If you’ve gone the take-home route, hang onto your custom tray, since it’s yours to use for touch-up sessions whenever your smile needs a refresh.
| Keep doing | Limit where you can |
|---|---|
| Brushing and flossing daily | Coffee and tea (or rinse with water after) |
| A scale and clean every six months | Red wine and curry |
| Using your custom tray for touch-ups | Smoking or tobacco use |
Quick Answers: Teeth Whitening FAQs
Does teeth whitening hurt?
Most patients feel little to no pain. Some notice mild, temporary sensitivity to hot or cold in the first few days, which usually settles on its own.
Will whitening work on crowns, veneers or fillings?
No. Porcelain and composite materials don’t respond to bleaching gel, so existing dental work will stay the same shade while your natural teeth lighten.
How long do results last?
Generally six months to two years, depending on your diet, smoking habits and how well you keep up your oral hygiene afterwards.
What’s the difference between in-chair and take-home whitening?
In-chair whitening is done in a single supervised appointment at our clinic for faster results. Take-home kits use your custom tray over 14 consecutive days or nights, for gradual whitening on your own schedule.
Do I need a check-up first?
Yes. A scale and clean clears surface plaque so the gel can reach your enamel evenly, and lets us check for cavities or gum issues first. Our first-time check-up and clean is $190.
