What Is Teeth Whitening?
Teeth whitening is a non invasive cosmetic treatment that lightens the natural colour of your teeth by breaking down stains that have developed over time. Unlike whitening toothpastes or over-the-counter products, professional whitening uses clinically approved whitening agents, carefully applied under the supervision of your dentist for safer, more predictable results. The treatment is designed to brighten your natural smile while maintaining the health of your teeth and gums.
What Causes Teeth to Become Discoloured?
It’s normal for teeth to lose some of their brightness over time. Several factors can contribute to staining and discolouration, including ageing and natural wear of tooth enamel; coffee, tea and red wine; soft drinks and coloured foods; smoking and tobacco use; certain medications; previous dental trauma; and poor oral hygiene. A professional examination helps determine the cause of your discolouration and whether whitening is the most suitable treatment for you.
Benefits of Professional Teeth Whitening
Professional whitening is one of the more straightforward ways to enhance your smile without altering your natural tooth structure. Benefits can include a noticeably brighter, whiter smile; removal of stains caused by food, drinks and smoking; treatment performed under professional supervision; more consistent results than many over the counter products; increased confidence when smiling; and a non-invasive approach. Many patients choose whitening before events or milestones, while others simply want to refresh their smile.
Is Teeth Whitening Right for You?
Professional whitening is suitable for many adults with healthy teeth and gums. It may be a good option if you have yellow or stained teeth, general discolouration from ageing, surface stains from food and drink, and a healthy mouth free from untreated tooth decay or gum disease. During your consultation, your dentist will assess your oral health and discuss whether whitening is likely to achieve your desired results. In some cases, alternative treatments such as veneers or crowns may be recommended if whitening is unlikely to improve certain types of staining.
Teeth Whitening at Our Sydney Clinics
At About Smiles, our team brings more than 80 years of combined dental experience and provides personalised cosmetic care, taking the time to understand your goals before recommending the right treatment. A whitening consultation can be carried out by our general dentists across the clinics, using professional-grade whitening products and modern techniques, with your comfort and oral health kept front of mind.
If whitening alone isn’t likely to fully achieve the result you’re after, our team can talk you through complementary options such as veneers in the same consultation at our Circular Quay clinic, Dr Aodhan Docherty provides teeth whitening, porcelain veneers and composite bonding as part of his confirmed cosmetic scope. As an NSQHS accredited group, we follow recognised national safety and quality standards. Some of our clinicians consult in additional languages Vietnamese at Circular Quay (Dr Gregory Nguyen), and Mandarin and Cantonese at Chatswood and Crows Nest (Dr Mark Mingjie Lu).
What to Expect During Teeth Whitening Treatment
Every smile is different, which is why your treatment begins with a comprehensive assessment.
Initial consultation. Your dentist examines your teeth and gums, discusses your goals and determines whether whitening is appropriate for you. Any existing dental problems should be addressed before whitening begins.
Professional teeth cleaning. Many patients benefit from a professional scale and clean before whitening removing plaque and surface stains allows the whitening treatment to work more effectively.
Whitening treatment. Depending on your needs, your dentist recommends the most appropriate professional whitening option. The whitening gel is carefully applied according to clinical guidelines to lighten the colour of your teeth while protecting your gums. Your dentist will explain the expected results and how to maintain your brighter smile.
How Long Does Teeth Whitening Last, and Is It Safe?
The longevity of your results depends on your lifestyle and oral hygiene habits. To help keep your smile brighter for longer, brush twice daily with fluoride toothpaste, floss every day, limit coffee, tea, red wine and coloured beverages where possible, avoid smoking and tobacco, and attend regular check-ups and professional cleans. Many patients choose to refresh their whitening periodically to maintain their desired shade.
When performed under the supervision of an experienced dentist, professional whitening is considered a safe and effective cosmetic treatment. Some patients may experience temporary tooth sensitivity following treatment, though this usually settles within a short period. Your dentist will discuss any potential side effects and how to help minimise sensitivity.

Frequently Asked Questions
How long before an event should I book teeth whitening?
It’s a good idea to book several weeks ahead where possible, particularly if a scale and clean is recommended beforehand or if any dental issues need addressing first. Your dentist can advise on realistic timing once your consultation is complete.
Will whitening work on crowns or veneers?
Whitening agents generally only affect natural tooth enamel, so existing crowns or veneers won’t change colour. Your dentist can talk through options if you have a mix of natural teeth and restorations you’d like to match.
Is teeth whitening permanent?
No, results fade gradually over time depending on your diet and habits, which is why many patients choose to top up their whitening periodically. Your dentist can advise on a suitable maintenance schedule.
Is teeth whitening available at all About Smiles locations?
Yes, professional teeth whitening is offered across our Sydney clinics: Chatswood, Circular Quay, Crows Nest, Eastgardens and Zetland, with a particular cosmetic focus at Circular Quay. Contact whichever is nearest to book a consultation.
Does whitening hurt?
Whitening itself isn’t usually painful, though some patients notice temporary tooth sensitivity afterwards, which generally settles within a short period. Let your dentist know if you’re prone to sensitivity so they can factor it into your treatment.
