What is Philips Zoom Teeth Whitening?
Philips Zoom Teeth Whitening is a professional in-chair treatment that uses a combination of bright UV light and bleaching agents, such as hydrogen peroxide gel, to whiten your teeth. It’s a popular choice, primarily due to its safe, efficient, and non-invasive process for effective and long-lasting results.
The entire procedure typically takes 90-120 minutes, during which a qualified dental professional will apply a protective layer to your gums and a whitening agent to your teeth. A high-intensity light is then used to activate the bleaching agent, allowing it to penetrate tooth enamel and remove deep stains through a process known as oxidisation.
While optimal results vary from one patient to the next, a dental professional will reapply that gel under the light in up to four 15-minute sessions to help encourage your brightest smile. Results will vary depending on your individual circumstances, but some patients experience an uplift of up to 8 shades whiter according to Philips1, the leader in teeth whitening.
Factors Affecting the Cost of Zoom Teeth Whitening in Australia
On average, the cost of professional in-chair teeth whitening in Sydney can range from $490 to $1,200, but estimates alone won’t determine whether you’re getting the right treatment for your smile. A lower price may seem appealing at first, but it is important to assess every different factor that may affect the cost of treatment.
The Australian Dental Association advises that only registered dental professionals possess the appropriate training and knowledge to assess which whitening treatment is right for you2. Cheaper and unregulated services may be available in some locations, like cosmetic salons, but only a qualified dentist can help ensure that your treatment meets the safety and quality regulations for dental procedures in Australia3.
Let’s now take a look at some of the other key factors that can affect the cost and result of Zoom laser teeth whitening:
Brands and Equipment Used
High-quality products and premium brands can help with the whitening process, but are generally more expensive to source and use, and may incur higher fees.
Overall Oral Health
It is essential to have a check-up prior to whitening to ensure you have no underlying oral health issues. If existing issues are present, such as periodontal disease, untreated decay or failing restorations, they should be treated prior to commencing whitening treatment to avoid causing further harm to the teeth. The dentist will also be able to let you know if you are a good candidate for successful whitening. This relates to the presence of fluorosis, shade of stains we are trying to lift (i.e. yellow or grey), existing dental work on your front teeth and any areas of thinning enamel among other factors.
Clean prior
Removing plaque, calculus and stains on the superficial surface of the teeth with a routine dental clean prior to whitening best allows the whitening gel to make direct contact with the enamel. This enables it to evenly target deeper discoloration without physical barriers. Ideally the clean is performed within 2 weeks of the in-chair whitening.
Existing Dental Work
If you have crowns, veneers, “caps” or fillings visible in your smile, it is important to know that these existing treatments will not brighten with whitening treatment. To maintain uniform colour after whitening, these restorations may benefit from replacement for optimum results. This is usually performed 1-2 weeks after the whitening treatment.
Combination Treatments
To maximise results, your dentist may recommend the use of additional take-home kits to either further enhance your in-chair results or for maintenance.

Zoom Teeth Whitening vs Other Teeth Whitening Options
Store-bought teeth whitening kits (not to be mistaken for professional at-home teeth whitening kits) may cost less than professional in-chair options like Philips Zoom, and they may feel more convenient, but there are some key differences that can affect the results of your teeth whitening.
Care is taken during professional in-chair treatment to ensure no whitening agent reaches your gums, minimising the risk of irritation or burning sensation. Store-bought treatments, however, are designed as a one-size-fits-all solution, and as no two mouths are the same, these are not tailored to avoid your gumline, so you may end up with whitening gel on your gums.
Over-the-counter DIY kits are required by law to contain lower concentrations of hydrogen peroxide (<6%), so while some products can brighten your teeth, they may not offer the same outcome as professional-grade bleaching agents.
On the contrary, Philips Zoom’s whitening formulas are approved by the Australian Dental Industry Association4, and can brighten teeth by up to eight shades in a single session under ideal conditions. The procedure must, however, only ever be carried out by a qualified dental professional in Sydney.
How Long Do Zoom Teeth Whitening Results Last?
The simple answer to how long teeth whitening results will last is highly dependent on a patient’s individual circumstances and commitment to ongoing maintenance.
Patients can expect to get 6 months to up to 3 years out of their treatment. As Dr Rebecca Amerena-Cowie explains, “All tooth whitening requires maintenance. You may choose zoom in-office procedure again or use a maintenance produce 1-3 nights every 4-6 months.”
How to Maintain Your Results After Zoom Teeth Whitening
If you want to maintain the results of any Zoom teeth whitening treatment, routine care is essential.
Good tooth maintenance hinges on your oral hygiene and lifestyle. For example, regular brushing and flossing can help to keep your gums and teeth healthy, and with the addition of routine dental check-ups, you can detect any problems early and stop them from developing into a more serious dental concern.
Your smoking habits and diet will also play a major role in preserving your whitened smile. Highly pigmented food and drinks like red wine, coffee, tea, certain fruits, or tomato-based sauces are more likely to stain your teeth over time than the likes of water, chicken, or rice.
You don’t have to eliminate your favourite snacks from your diet to benefit from teeth whitening, but it is highly recommended that you always use a straw and rinse your mouth with water or chew sugar free gum eating or drinking , to prevent food from staining your teeth.
