Teeth Whitening

Lighten your natural teeth with dental advice

Whitening lightens the natural colour of your teeth. It does not change the colour of fillings, crowns or veneers, so your dentist looks at your teeth first and explains what to expect for yours.

Ask us about in-chair and take-home whitening. For current fees, call us on (02) 4284 4486 or read Our fees. You can also see our Patient offers.

How whitening works

Whitening bleaches your teeth to lighten the colour of the enamel. The active ingredients are hydrogen peroxide or carbamide peroxide, usually in a gel, sometimes with a light. Only registered dental professionals can use strong whitening gels with more than 6% hydrogen peroxide.

These professionals have the training to assess whether bleaching suits you. Whitening is one of our Cosmetic Dentistry services.

Why teeth change colour

Teeth stain on the outside when you drink tea, coffee or red wine or eat foods such as spices, berries or beetroot. The white enamel can also wear thinner as you get older, which exposes the yellowish dentine underneath. Teeth can also be discoloured from the inside after an injury, after certain medicines taken in early childhood, or after Root canal treatment.

If the cause is deep inside a tooth, gel applied to the outside will not make it whiter, and in some cases a dentist can bleach inside the tooth.

In-chair and take-home options

Your dentist can provide in-chair whitening, where a strong hydrogen peroxide gel is applied, often with a light, and you should have whiter teeth after one appointment. With take-home whitening, your dentist has thin plastic trays custom made to fit your teeth and gives you gel in the strength you need.

Take-home whitening takes longer to achieve results than in-chair treatment, which does not mean the final result is better or worse. Ask us which options suit your teeth.

When whitening may not suit you

Whitening is not recommended if you are pregnant or breastfeeding, have cracks or holes in your teeth, or have untreated dental problems. It will not work on crowns, veneers or fillings, so these can end up a different shade from your whitened teeth.

That is why a Check-up and clean comes first, and why your dentist may suggest Tooth fillings or Gum disease treatment before you whiten.

Risks and sensitivity

Whitening has some risks. Your teeth may be sensitive to cold straight after treatment and your gums and the inside of your mouth may feel irritated; see your dental professional if this continues for more than 1 or 2 days. Strong products can cause irritation or burns, swallowing whitening gel is dangerous, and if you have cracks in your teeth the bleach could cause pain or further damage.

Follow your dentist's instructions for take-home trays.

Over-the-counter products

You can buy whitening kits online, in pharmacies and at the supermarket, and some salons offer whitening. Kits and non-qualified providers can put you at risk of harm. At-home kits do not contain the same concentration of bleaching agents that dental practitioners use.

Whitening toothpaste can reduce stains on the outer surface of your teeth, but it can also make your teeth sensitive. Read the Guide to teeth whitening for the full picture.

Looking after the colour of your teeth

Other ways to look after the colour of your teeth include a professional clean, brushing and flossing every day, rinsing your mouth with water after food and drink that stain, and not smoking. If you would like a change of shape as well as colour, ask about Porcelain veneers, and read about Payment options before you book.

You can ask for a pause or decline a proposed treatment after discussing the options and risks with your dentist.

When to ask about whitening

Whitening is a choice about appearance, and it is not suitable for everyone. These are the situations in which people most often ask, and your dentist checks your teeth before advising.

  • Stains from food and drink: Coffee, tea, red wine or smoking has stained your teeth.
  • Teeth darkened with age: Your teeth have gradually become darker.
  • An event coming up: You would like to plan whitening ahead of a special occasion.
  • A check first: Decay or gum disease usually needs care before whitening, so ask for a check.

What happens at your visit

Whitening starts with a check, not with bleach. Your dentist explains what is realistic for your teeth before you choose an option.

  • A check before whitening: Your dentist looks at your teeth and gums.
  • Your goals: You talk about the shade you would like and what is realistic.
  • Your options explained: You hear how in-chair and take-home whitening differ.
  • Aftercare advice: You hear what to expect afterwards, including sensitivity.

Frequently Asked Questions

Questions about Teeth Whitening

These general answers can help you prepare questions for an individual conversation.

The most useful thing you can bring is a description of what bothers you. Is it an overall dullness, or one tooth that looks darker than its neighbours? A single dark tooth often has a different cause from general staining, and the dentist can only work out which after looking at it. Say when you first noticed the colour and whether that tooth has had an injury or earlier treatment.

Please do not expect a particular shade. Teeth whitening guide explains that results differ from person to person, so nobody can promise a result from a photo or a shade chart. A better question is what whitening might change in your mouth and what it would leave as it is.

If you are also thinking about shape or spacing, our cosmetic dentistry page gives a wider view of what can be discussed. Whitening is an optional, cosmetic choice, so you can take your time and ask for your options to be explained again if anything is unclear.
