How does professional teeth whitening work?
Professional whitening uses hydrogen peroxide to gently break down stain molecules within the tooth.
• Stains exist within enamel and underlying tooth structures
• Hydrogen peroxide penetrates enamel safely
• Stain molecules are broken into smaller, less pigmented compounds
• These compounds absorb less light
• More light is reflected back to the eye
• Teeth appear brighter — without changing tooth structure

MID AND LIGHT OPTIONS BELOW:
Is professional teeth whitening safe for teeth?
Yes — when delivered within clinical guidelines. Professional whitening alters stain molecules within the tooth without removing or weakening enamel. Gel formulation, including controlled oxygen free-radical activity and balanced pH, is key to managing enamel stress and sensitivity.
Why choose professional whitening over cosmetic salon whitening?
Professional whitening includes oral health screening, gum protection, controlled exposure, and careful monitoring throughout treatment. As a registered dental hygienist with a three-year qualification and over 11 years of clinical experience, I tailor each treatment to individual teeth and oral health needs rather than applying a one-size-fits-all cosmetic approach.
Will whitening cause sensitivity?
Temporary sensitivity can occur with peroxide-based teeth whitening.
At Polish + White, sensitivity risk is assessed in advance and monitored throughout treatment. Supportive measures may be used to help maintain enamel hydration and comfort, including nano-hydroxyapatite, Pro-Argin–based desensitising agents, and protective surface barriers. If sensitivity occurs, it is often mild and short-lived.

Introduction to Whitening - light strength
$150
A gentle first step
Suitable for first-time whitening clients or those wanting to experience professional whitening conservatively.
This option allows you to explore whitening in a controlled setting and assess how your teeth respond before progressing further. Perfect for a brighten up before a big event - combined with a polish to remove surface, tea or coffee stains.
Maintenance Whitening - light strength
$129
Ongoing brightness support
Designed for clients who have previously completed professional whitening at Polish and White and wish to maintain or lightly refresh their results over time. “After whitening, teeth gradually settle into a new lighter baseline. Short low strength , regular 3-4 month top-ups in the first year help reinforce that colour, so results tend to last longer and require less effort over time.”
How long does whitening results last?
Most clients maintain results for around 12 months, some 2-3 years. Those with a highly pigmented diet (such as red wine or coffee) may notice fading sooner — often around 6–9 months
Low-strength maintenance whitening can help refresh brightness and extend results.
How often do I need maintenance whitening?
Clinical studies show that most colour rebound occurs in the first year after whitening. Short, low-dose maintenance every 3–4 months during this period helps stabilise the lighter shade. Once colour has settled, maintenance is usually only needed every 6–12 months.”
Can crowns, veneers, fillings or bonding be whitened?
Teeth whitening only affects natural teeth. Crowns, veneers, fillings and bonding do not change colour and may need review after whitening for colour matching.
Unsure which option is right for you ?
A complimentary consultation allows us to assess suitability and recommend the most appropriate whitening approach.
