Why Teeth Lose Their Brightness
Tooth discolouration is a natural part of ageing, but lifestyle factors accelerate the process considerably. Coffee, tea, red wine, and certain spices stain the outer enamel over time, while smoking leaves deep-set yellowish deposits. Even some medications, particularly tetracycline antibiotics taken during childhood, can cause intrinsic staining that surface cleaning alone cannot address.
Understanding the type of staining you have is the first step toward choosing the right whitening method.
Professional In-Clinic Whitening
In-clinic whitening uses a high-concentration hydrogen peroxide or carbamide peroxide gel, often activated by a specialised light or laser. The entire procedure takes approximately 60 to 90 minutes and can lighten teeth by several shades in a single session.
Advantages:
- Immediate, visible results
- Controlled application reduces gum sensitivity
- Supervised by a dental professional
- Custom trays ensure even coverage
At-Home Whitening Kits
Over-the-counter strips, trays, and pens use lower concentrations of the same active ingredients. They are more affordable but require consistent daily use over two to four weeks to achieve noticeable results.
