Professional Teeth Whitening in Adelaide

Professional teeth whitening uses a peroxide-based gel to break down and lift stain molecules embedded in your tooth enamel. At Lidums Dental, we offer take-home whitening kits with custom-fitted trays made from impressions of your teeth, this ensures even coverage and a closer fit than anything available over the counter. The custom trays also mean you can top up your results at home over time, making it one of the most cost-effective cosmetic treatments available.

Whitening works best on natural tooth enamel discoloured by food, drink, or ageing. It is not effective on crowns, veneers, bonding, or porcelain restorations, those materials don’t respond to peroxide. Whitening is also not recommended for patients with active gum disease, significant decay, or for pregnant or breastfeeding women. This is why a professional assessment matters — Dr Lidums or our team will confirm whether whitening is appropriate for you before you begin, and flag any underlying issues first.

Not always, and this is important to understand before you start. Teeth naturally vary in their baseline shade, and some areas — particularly near the gumline or on the edges — may lighten faster than others. Teeth with internal staining (from antibiotics like tetracycline, or fluorosis) respond poorly to peroxide whitening and may require veneers or other treatment to achieve a uniform result. Custom trays help maximise even coverage, which is one reason professional whitening consistently outperforms store-bought strips.

Some sensitivity during and shortly after whitening is common, this is because peroxide temporarily opens the pores in your enamel, making teeth more reactive to temperature. In most cases this resolves within 24–48 hours. It is not permanent. Patients who already experience sensitivity may find it more pronounced, and our team can recommend desensitising gels or a modified protocol to manage this. If sensitivity is severe or persists, stop use and contact the practice.

The most natural-looking results tend to match the whites of your eyes. Beyond that, whitening can start to look artificial. During your consultation, our team will help you choose a realistic target shade based on your skin tone, your existing restorations, and your personal preference. As for longevity, professional whitening typically lasts 1–2 years depending on your diet and habits. Coffee, tea, red wine, and smoking all accelerate fading. Because you keep your custom trays, maintenance top-ups are straightforward and affordable.

Before starting, ensure any outstanding decay or gum issues are treated, whitening over active dental problems can cause discomfort and uneven results. During the whitening period, avoid staining foods and drinks where possible, and do not smoke. Afterwards, maintain results with good brushing habits and periodic top-ups using your custom trays. If you’re planning other cosmetic work, such as veneers or bonding, whiten first, as restorations are shade-matched to your final tooth colour and cannot be whitened later.
