Teeth Whitening: What Works and What Doesn’t?
If you’ve ever searched for ways to achieve a brighter smile, you’ll know there’s no shortage of options. From supermarket strips to online “miracle” kits, teeth whitening advice is everywhere — but not all of it is accurate.
At Smile Haus, we’re often asked: What actually works when it comes to teeth whitening? And just as importantly — what doesn’t?
If you’re considering teeth whitening in Shenton Park or the wider Perth area, here’s what you need to know.
Why Do Teeth Become Discoloured?
Before choosing a whitening treatment, it helps to understand why teeth stain in the first place.
Common causes include:
Coffee, tea and red wine
Smoking or vaping
Natural ageing
Certain medications
Inadequate oral hygiene
Some stains sit on the surface of the enamel, while others occur deeper within the tooth structure. The type of discolouration affects which whitening treatments will actually work.
What Works: Professional Teeth Whitening
1. In-Chair Teeth Whitening
Professional in-chair teeth whitening performed by a dentist remains one of the safest and most effective ways to achieve noticeable results quickly.
At Smile Haus, we use clinically proven whitening systems that:
Contain safe, regulated whitening agents
Are applied with gum protection
Deliver visible results in a single appointment
In-chair whitening is ideal if you’re preparing for a special event or want immediate improvement.
2. Take-Home Professional Whitening Kits
Custom take-home whitening kits provided by your dentist are another highly effective option.
These differ from store-bought kits because:
The trays are custom-made to fit your teeth precisely
The whitening gel is professional-grade
You receive guidance to minimise sensitivity
This method allows you to whiten gradually and maintain control over your results.
For many patients in Shenton Park, this is a convenient and reliable long-term solution.
What Sometimes Works (With Limitations)
Whitening Toothpaste
Whitening toothpaste can help remove surface stains over time. However, it does not change the natural colour of your teeth.
These products are best viewed as maintenance tools — not transformative whitening treatments.
Over-the-Counter Whitening Strips
Some pharmacy whitening strips contain mild bleaching agents and can produce subtle improvements.
However:
Results are usually limited
One-size-fits-all trays may irritate gums
Overuse can increase tooth sensitivity
Without professional supervision, outcomes are unpredictable.
What Doesn’t Work (Or Isn’t Worth the Hype)
Charcoal Toothpaste
Activated charcoal products are heavily marketed online, but there is limited clinical evidence supporting their whitening claims.
In some cases, charcoal can be abrasive and contribute to enamel wear — which may actually increase staining over time.
DIY Home Remedies
Social media trends like baking soda and lemon juice are not safe whitening solutions.
Acidic or abrasive DIY methods can:
Damage enamel
Increase sensitivity
Lead to long-term dental issues
If it sounds too simple to be true, it usually is.
Routine visits to this Shenton Park dentist aren’t just about preventing cavities—they’re about giving your smile the love it deserves. With advanced tech (like digital imaging and gum health assessments) and personalised plans, we catch issues early, keep your smile glowing, and keep care uncomplicated.
Is Teeth Whitening Safe?
When supervised by a dentist, professional teeth whitening is considered safe for most patients.
However, whitening may not be suitable if you:
Have untreated tooth decay
Have active gum disease
Are pregnant or breastfeeding
Have restorations (crowns or veneers) that won’t change colour
That’s why a dental assessment is essential before starting any whitening treatment.
At Smile Haus, we assess your oral health first to ensure whitening is appropriate and safe.
How Long Do Whitening Results Last?
Results vary depending on lifestyle habits.
With proper maintenance and regular dental cleans, professional whitening can last from several months to a few years.
To prolong results:
Limit staining foods and drinks
Rinse after coffee or wine
Maintain six-monthly dental check-ups and cleans
Use dentist-recommended maintenance products
