Teeth whitening is a common cosmetic dental treatment in Brisbane. Retail product prices vary widely; at Ivy Dental, clinician-prescribed take-home whitening starts from $299 and in-chair whitening starts from $850. Understanding the assessment, materials, supervision, and follow-up included at each price point can help you compare options.
This guide covers the main whitening options available, what each costs, and what factors influence your results.
Whitening options and pricing
There are three broad categories of teeth whitening, each with different costs, active ingredients, and expected outcomes.
Option | Starting price | Application | Expected outcome |
|---|---|---|---|
In-chair professional whitening | From $850 | Applied by your dentist during a planned appointment | Shade response assessed after treatment |
Custom take-home kit (dental) | From $299 | Custom trays used at home under written instructions | Gradual lightening with prescribed gel |
Over-the-counter products | From $20 | Strips, pens, or generic trays from a pharmacy | Variable and typically more modest results |
Indicative pricing. Your quote may differ based on clinical assessment and the whitening system used.
Professional and over-the-counter whitening options
In-chair whitening
In-chair whitening is performed at the dental practice in a single appointment, typically lasting 60 to 90 minutes. Your dentist applies a concentrated hydrogen peroxide gel to the teeth, sometimes activated by a light source. The gums and soft tissues are protected with a barrier before the gel is applied.
The concentration of active ingredient used in-chair is significantly higher than what is available in retail products. In Australia, products containing more than 6% hydrogen peroxide can only be applied by a registered dental practitioner. This is the main reason professional whitening tends to produce more noticeable results than over-the-counter alternatives.
Custom take-home kits
Take-home whitening involves custom-fitted trays made from dental impressions of your teeth. You fill the trays with a professional-grade whitening gel (typically lower concentration than in-chair) and wear them for a specified period each day, usually 30 to 60 minutes or overnight, depending on the product.
Results develop gradually over the prescribed course. A lower-concentration gel may reduce sensitivity for some patients, although sensitivity can still occur. Existing trays should be checked before reuse because dental work, tooth position, tray fit, and oral health can change; use only the gel and schedule your clinician provides.
Over-the-counter products
Whitening strips, pens, and generic tray kits from pharmacies use lower concentrations of active ingredients. Results vary considerably and are generally more modest than professional options. Generic trays do not fit as precisely as custom trays, which can lead to uneven whitening and gel contact with the gums.
These products are not harmful when used as directed, but they are limited by the concentration of active ingredient permitted in retail products in Australia.
What affects whitening results?
Not everyone responds to whitening in the same way. Several factors influence how much lighter your teeth will become and how long the results last.
Type and cause of discolouration
Whitening is most effective on extrinsic staining caused by food, drinks, and tobacco. Coffee, tea, red wine, and curries are among the most common culprits. This type of staining sits on or within the outer enamel layer and responds well to peroxide-based whitening.
Intrinsic discolouration, caused by factors such as tetracycline antibiotics, fluorosis, or trauma, is more difficult to address with whitening alone. In some cases, dental veneers or composite bonding may be more appropriate. Your dentist can assess the type of discolouration during a consultation.
Existing dental work
Whitening gel only affects natural tooth structure. Fillings, crowns, and veneers will not change colour. If you have visible restorations in your smile zone, whitening your natural teeth may create a mismatch. Planning is important. Your dentist may recommend whitening first, then replacing visible restorations to match the new shade. For more detail, see our article on whitening with crowns or fillings.
Tooth sensitivity
Some patients experience temporary sensitivity during or after whitening, particularly with higher-concentration products. This is usually short-lived and resolves within a few days. If you have a history of sensitive teeth, your dentist can recommend a lower concentration or a desensitising protocol to manage this.
Book a whitening consultation to find out which option may suit your teeth and your budget.
Starting shade and expectations
Teeth that are moderately stained typically show the most dramatic improvement. Teeth that are already relatively light may see a subtler change. Your dentist can assess your current shade and give you a realistic expectation of what whitening can achieve for your specific situation.
How to maintain whitening results
The longevity of your results depends largely on what happens after treatment. Common recommendations include:
- Reducing intake of staining foods and drinks in the first 48 hours after treatment (the "white diet" period)
- Rinsing with water after consuming coffee, tea, or red wine
- Maintaining good oral hygiene with twice-daily brushing and regular dental check-ups
- Clinician-guided maintenance only when needed, after confirming that your trays still fit and that your teeth and gums remain suitable
For a detailed guide, see our teeth whitening aftercare article.
With maintenance, professional whitening results can last 12 to 24 months or longer. Without it, restaining typically becomes noticeable within 6 to 12 months.
Is professional whitening worth the cost?
The short answer is that it depends on your goals and your starting point. Professional whitening adds a dental assessment, clinician-selected materials, a prescribed schedule, and a plan for sensitivity. Over-the-counter products cost less but do not include those individual checks.
For patients with extrinsic staining who are clinically suitable, professional whitening may be considered. A previous whitening treatment does not make a self-directed top-up automatically safe: tray fit, current restorations, sensitivity, decay, and gum health should be reviewed first.
If your primary concern is the colour of your teeth but you also have chips, gaps, or misalignment, it may be worth discussing veneers or aligners as part of a broader treatment plan. Whitening is often the first step in a smile makeover because other restorations are then matched to your new, lighter shade.
Next steps
If you are considering teeth whitening and want to understand which option may work for your situation, a consultation is the most reliable starting point. Your dentist can assess your tooth shade, check for any issues that need addressing first (such as decay or gum disease), and recommend an appropriate approach.
