Whiter teeth. One session.

Professional teeth whitening is a dentist-supervised cosmetic procedure that lightens the colour of natural teeth using medical-grade hydrogen peroxide or carbamide peroxide gel. At Ark Dental Global, we use Philips Zoom! LED-activated whitening for in-office treatment — the world's most popular professional whitening system. Results are visible in a single 60-minute session with up to 8 shades of improvement. Custom take-home trays are also available for gradual whitening.

Professional teeth whitening results typically last 1-3 years depending on diet, lifestyle and oral hygiene. Smokers and frequent coffee, tea or red wine drinkers may need touch-ups sooner (6-12 months). Patients with disciplined oral care can maintain results for 2-3 years. We provide take-home maintenance kits for gradual touch-ups and recommend annual in-office refreshers.

Yes — when performed by a qualified dentist using approved products. Philips Zoom! whitening uses clinically tested hydrogen peroxide concentrations with gum isolation barriers to protect soft tissue. The procedure does not damage enamel when performed correctly. Over-the-counter strips and toothpaste are less effective and can cause uneven results or gum irritation when used improperly.

Mild temporary sensitivity is common — typically lasting 24-48 hours after treatment. At Ark Dental Global, we use a desensitising protocol that significantly reduces this: pre-treatment fluoride application, controlled gel concentration and post-treatment desensitising paste. Patients with pre-existing sensitive teeth can opt for gentler take-home whitening or shorter in-office sessions.

Each has advantages. In-office Philips Zoom! delivers fastest results (8 shades in 60 minutes) and is best for stained teeth, special occasions, or first-time whitening. Take-home custom trays are ideal for gradual whitening, ongoing maintenance, or those with sensitive teeth — typically 2-3 weeks to full result. The combination approach (in-office + take-home maintenance) delivers the longest-lasting outcome and is what we recommend for most patients.

No. Whitening gel only affects natural tooth enamel — it cannot change the colour of porcelain crowns, veneers, composite fillings or bonding. If you have existing restorations in your smile zone, we discuss this during consultation. Often the solution is to whiten natural teeth first, then replace older restorations to match the new shade.

Most patients achieve 6-8 shades of improvement on the Vita shade guide with Philips Zoom! treatment. Your final shade depends on starting colour, type of stains (extrinsic stains from food respond best; intrinsic stains from antibiotics or fluorosis respond less), enamel quality and tooth structure. We assess realistic outcomes during your consultation — your AI 3D smile simulation can preview the expected result.

Yes, professional whitening effectively removes tobacco staining. However, results last shorter for active smokers (often 6-9 months vs 2-3 years for non-smokers). We recommend pairing whitening with smoking cessation guidance for lasting results. Take-home maintenance trays are especially valuable for smokers to refresh whiteness monthly.

We do not perform teeth whitening during pregnancy or breastfeeding as a precaution. While no studies show whitening gel is harmful, there is insufficient research on prenatal exposure. We recommend postponing whitening until after pregnancy and nursing. Other oral care (cleaning, fillings) continues safely throughout.

Five strategies: 1) Avoid staining foods and drinks for 48 hours after whitening (coffee, tea, red wine, curry, berries, dark sauces), 2) Use a straw for staining beverages long-term, 3) Brush twice daily with whitening toothpaste, 4) Schedule annual in-office touch-ups, 5) Use take-home maintenance trays every 3-6 months. Quit smoking for the longest-lasting results.
