A brighter smile is one of the most common requests we hear at Louis Dental Surgery. But with charcoal toothpaste, whitening strips, UV kits, and countless other products flooding the market, it's hard to know what actually works — and what might harm your teeth.
Why Do Teeth Become Yellow?
Tooth discoloration happens for several reasons: coffee, tea, and red wine stain the enamel over time. Ageing naturally darkens teeth as enamel thins and the yellowish dentin underneath shows through. Smoking is one of the worst culprits, causing deep stains that are difficult to remove.
Over-the-Counter Products: Do They Work?
Whitening toothpastes can remove surface stains but won't change the actual colour of your teeth. Whitening strips and gels can provide mild improvement, but the concentration of bleaching agent is much lower than professional treatments, so results are limited and uneven.
The Charcoal Trend: A Warning
Activated charcoal toothpaste has become trendy, but there's no scientific evidence that it whitens teeth. In fact, it's abrasive enough to wear down enamel over time — the opposite of what you want.
Professional Whitening: The Gold Standard
In-clinic whitening uses professional-grade bleaching agents at higher concentrations, applied under controlled conditions by your dentist. Results are visible in a single session — often up to 8 shades lighter. It's faster, more effective, and safer than any at-home product.
How to Maintain Your Results
After whitening, avoid dark-coloured foods and drinks for 48 hours. Use a straw for coffee and tea. Brush twice daily and keep up with your regular scaling appointments. With proper care, professional whitening results can last 1-2 years.
