Teeth Whitening Options: What Works Best?
By Dr David Vickers
If you're dreaming of a whiter, brighter smile, you're not alone. Teeth whitening is one of the most popular cosmetic dental treatments in Australia. At Northbridge Dentists, we offer a range of safe and effective teeth whitening options to suit different needs and budgets. But with so many choices on the market, it’s important to understand what works and what doesn’t.
Below, we break down the most common teeth whitening treatments, how effective they are, and what to expect from each.
1. In-Chair Whitening (Professional Teeth Whitening at the Dentist)
What is it?
In-chair whitening is performed in the dental clinic using a highly concentrated hydrogen peroxide gel, often activated by a specialised LED light or laser. This is the most powerful form of professional teeth whitening.
Effectiveness:
⭐️⭐️⭐️⭐️⭐️
You’ll see dramatic results immediately — often a couple of shades whiter in just one visit.
Why choose this option at Northbridge Dentists?
Performed safely under dentist supervision
Fastest and most noticeable results
Ideal for special events or last-minute whitening
Considerations:
Higher initial cost
Possible short-term sensitivity
Other risks - particularly those with weaker teeth / existing sensitivity - to be discussed with your dentist.
2. Take-Home Whitening Kits (Custom Trays from Your Dentist)
What is it?
We create custom-fitted trays for your teeth and provide a professional-grade whitening gel to use at home over 1–2 weeks.
Effectiveness:
⭐️⭐️⭐️⭐️
Gradual, even whitening with long-lasting results — ideal for people who prefer to whiten at their own pace.
Benefits:
Dentist-recommended and monitored
More affordable than in-chair whitening
Ideal for ongoing maintenance or touch-ups
Downsides:
Requires daily commitment for 10-14 days
Slower than in-chair whitening
3. Over-the-Counter Whitening Products
Options include:
Whitening strips
Whitening toothpaste
Whitening pens
LED light kits sold online
Effectiveness:
⭐️⭐️ to ⭐️⭐️⭐️
These products contain lower concentrations of active ingredients (usually around 5–6% hydrogen peroxide - the highest concentration legally available in Australia) compared to professional options.
Pros:
Readily available and affordable
Easy to use
Cons:
Less dramatic and slower results
Not customised for your teeth
Can cause uneven whitening or sensitivity if misused
4. DIY or Natural Whitening Methods
These include baking soda, activated charcoal, coconut oil (oil pulling), and apple cider vinegar.
Effectiveness:
⭐️
There is little to no evidence supporting these methods. Some can actually wear down enamel or irritate your gums.
Risks:
Damage to tooth enamel
No guarantee of results
Not supported by dental professionals
Which Teeth Whitening Option Is Best?
If you’re looking for safe, long-lasting and visible results, professional teeth whitening from your dentist is the gold standard. Whether you opt for in-chair whitening or a custom take-home kit, dentist-supervised treatments are more effective, safer, and tailored to your individual needs.
