A bright, white smile can instantly boost your confidence and make you feel more attractive. Over time, however, teeth can become stained from coffee, tea, red wine, smoking, and even the natural aging process. That’s where teeth whitening comes in.
Whether you’re getting ready for a big event or just want to refresh your smile, professional teeth whitening can deliver dramatic results safely and quickly. Here’s everything you need to know before starting your teeth whitening journey.
Why Do Teeth Get Discoloured?
Discolouration happens for several reasons, including:
Extrinsic stains: Surface stains from food, drinks, and smoking
Intrinsic stains: Deeper stains from trauma, medications, or aging
Enamel thinning: As enamel wears away, yellow dentin underneath becomes more visible
Understanding the type of stain helps determine the best whitening option for you.
Types of Teeth Whitening
1. In-Chair Teeth Whitening
This is done at the dental clinic using high-concentration bleaching agents (like hydrogen peroxide) activated by light or heat. Results are immediate—often several shades lighter in one session.
2. Take-Home Whitening Kits
Custom trays are made for your teeth, and you're given professional-grade gel to use at home. This is a safe, gradual method over 1–2 weeks, with long-lasting results.
What’s the Procedure Like?
For in-chair whitening:
Your gums are protected with a barrier
Whitening gel is applied to your teeth
A special light may be used to activate the gel
The process is repeated 2–3 times in a single session
You walk out with a brighter smile—instantly!
For take-home kits, your dentist will take impressions or scans of your teeth, create custom trays, and give you detailed instructions for safe application.
Is Teeth Whitening Safe?
Yes—when done under professional supervision. Whitening is one of the most studied cosmetic dental treatments and is generally safe for your teeth and gums.
However, side effects can include:
Temporary tooth sensitivity
Mild gum irritation
These usually subside within a few days. If sensitivity is a concern, your dentist may recommend a desensitising toothpaste or a gentler formula.
How Long Does It Last?
Whitening results typically last 6–12 months, depending on your diet, oral hygiene, and lifestyle habits. Avoiding staining foods and drinks and brushing regularly will help maintain your results.
Touch-up treatments can be done every few months or yearly.
How Much Does Teeth Whitening Cost?
In Australia:
In-chair whitening: $600–$1,200
Custom take-home kits: $250–$500
OTC products: $20–$100
Many dental clinics offer whitening packages or specials—check with your dentist.
Who Should Avoid Whitening?
Teeth whitening may not be suitable for:
Children under 16
Pregnant or breastfeeding women
Patients with untreated cavities or gum disease
People with dental restorations (crowns, veneers, or fillings) on front teeth—these won’t whiten
Your dentist will assess your oral health and goals before recommending whitening.
Conclusion: Whiter Teeth, Brighter Confidence
Teeth whitening is a safe, fast, and non-invasive way to enhance your smile. Whether you choose in-chair whitening or a custom take-home kit, professional treatments deliver better and longer-lasting results than supermarket products.
