What Causes Tooth Discolouration?
Teeth can darken over time from coffee, tea, red wine, smoking, and ageing. Some stains are external (on the surface), while others occur deeper inside the tooth.
Professional vs. DIY Whitening
Over-the-counter kits often promise dramatic results but can damage enamel or cause sensitivity. The safest and most effective whitening comes from a professional dentist-supervised treatment using regulated whitening gels.
How Professional Whitening Works
Your dentist takes a custom mould of your teeth and provides whitening trays with safe peroxide-based gels. Results are visible within 1–2 weeks and last far longer than shop products.
Tips for Maintaining Your White Smile
- Avoid staining drinks for 48 hours post-whitening
- Brush twice daily with fluoride toothpaste
- Attend hygiene visits regularly
