Teeth whitening in Jordan Springs and Penrith

Whitening lifts staining out of natural tooth enamel using a peroxide gel, either in one appointment here or with custom trays you wear at home. It's the least invasive cosmetic treatment there is, nothing is drilled and nothing is permanent. The thing most people don't know until afterwards is that it only works on natural teeth, so any crowns, veneers or white fillings stay exactly the shade they are.

This is usually considered when

Understanding the core signs of advanced dental distress is crucial. Early intervention can safeguard your natural smile, alleviate ongoing discomfort, and prevent structural issues from escalating further.

What's involved, step by step

About 30 minutes

Checking your teeth are ready

An examination first. Decay, gum disease, cracks or exposed root surfaces all make whitening uncomfortable or uneven, and need treating beforehand. We'll also record your starting shade and tell you honestly how much change to expect, because that varies a lot between people.

60 to 90 minutes

In-chair whitening

Your gums are protected, a stronger gel is applied to the teeth and left on in cycles. You leave the same appointment with the result. Most people notice sensitivity that evening, settling within a day or two.

Two visits, then 10 to 14 nights

Or take-home trays

Impressions or a scan are taken and thin custom trays are made to fit your teeth exactly. You wear them with a milder gel, usually overnight, for one to two weeks. Slower, gentler on sensitivity, and you keep the trays for topping up later.

Recovery and aftercare

Whitening isn't a procedure you recover from, but it does make teeth temporarily more porous, which means they pick up stain easily for a day or two and can be sensitive to cold. Both settle. The first 48 hours are the ones that matter — what you eat and drink then has a real effect on how the result holds.

The first 48 hours

Avoid anything that would stain a white shirt: coffee, tea, red wine, curry, beetroot, soy sauce, berries. Stick to pale foods and water. Don't smoke. This is the window where teeth reabsorb colour most readily.

Short sharp twinges to cold are common, usually peaking the evening after in-chair whitening and gone within a day or two. A sensitive-teeth toothpaste used for a week beforehand reduces it. Tell us if you're prone to sensitivity and we'll plan around it — usually with trays rather than in-chair.

Whitening isn't permanent. The colour fades gradually over one to three years depending on what you drink and whether you smoke. Custom trays make topping up straightforward — a night or two every so often rather than starting again.

Risks and things to consider

Sensitivity is the most common effect and is usually short-lived, but it can be significant for a day or two, particularly after in-chair whitening. Gum irritation can occur if gel contacts the gum, and settles quickly. Results vary considerably between people and cannot be predicted precisely. Yellow and brown discolouration generally responds well; grey discolouration, including staining from tetracycline, responds poorly or not at all. Whitening has no effect on crowns, veneers, bonding or white fillings. If you have visible restorations on your front teeth, whitening the teeth around them will make them stand out, and they may need replacing afterwards to match — which is a cost worth knowing about before you start. If you have white spots from fluorosis, these often look more obvious immediately after whitening before evening out. A single dark tooth caused by past injury or root canal treatment usually needs internal whitening from inside the tooth rather than an external gel. Whitening is not recommended during pregnancy or breastfeeding, and generally not for teenagers, whose teeth have larger nerve chambers. Over-the-counter kits with ill-fitting trays can cause uneven results and gum burns.


Any surgical or invasive procedure carries risks. Before proceeding, seek a second opinion from an appropriately qualified health practitioner. Individual results vary.

Other options worth considering

A scale and clean first

Sometimes it's surface stain, and removing it is all that's needed.

Internal whitening

For one dark tooth after an old injury or root canal.

Veneers or bonding

For grey discolouration or marks whitening can't shift.

What affects the cost

The main factor is which method you choose. In-chair whitening costs more than take-home trays because it's a longer appointment with a stronger gel. Trays cost more the first time because they're custom-made to your teeth, but you keep them, and topping up afterwards only costs the gel. Some people do both — in-chair to get there quickly, trays to maintain it. If a clean or any treatment is needed beforehand, that's separate, and we'll quote it with the whitening so you see the whole picture.

Common questions

How much whiter will my teeth go?

It varies more than any other cosmetic treatment, which is why we won't quote you a number of shades. Yellowing from age and food usually responds well. Grey discolouration often doesn't. We'll record your starting shade and tell you what's realistic for your teeth before you book.

No. Whitening only works on natural tooth structure. If you have visible restorations on your front teeth, they'll stay the shade they are and may need replacing to match afterwards.

In-chair is faster and done for you. Trays are gentler on sensitivity and give you the means to top up later. Neither is better as a result — it's about how quickly you need it and how sensitive your teeth are.

Professionally supervised whitening at the concentrations we use doesn't damage enamel. What causes problems is unsupervised use of high-concentration products, or whitening teeth with untreated decay or exposed root surfaces — which is why the examination comes first.

Generally 9-12 months before it needs topping up, depending on what you drink and whether you smoke. Trays make maintaining it easy.

We don't recommend it during pregnancy or breastfeeding. It can wait.

They remove surface stain, which can make a modest difference, but they can't change the underlying colour of the tooth. Some are quite abrasive, so they're not ideal long term.

Yes. Porcelain can't be whitened once it's made, so any whitening happens first and the veneer shade is matched to the result. Doing it the other way round means replacing the veneers.
