Professional Teeth Whitening vs Home Remedies: What Actually Works

A brighter smile is one of the most requested cosmetic treatments, and one of the most misunderstood. Between social-media hacks and over-the-counter kits, it's hard to know what is safe and what actually works.

Why teeth stain

Teeth darken over time because of what we eat and drink (tea, coffee, cola, red wine, curries), tobacco and paan, and ageing: as enamel thins, the yellower layer beneath shows through. Some medicines, and old fillings or injuries that darken a tooth from within, can also play a part.

Home remedies: what works and what doesn't

• Baking soda is mildly abrasive and can lift surface stains, but using it often can wear away enamel.
• Lemon juice, vinegar and other acids may seem to whiten, but they soften and erode enamel, and damaged enamel is duller and more sensitive. Avoid them.
• Charcoal powders are abrasive, have no proven whitening benefit and can scratch enamel.
• Oil pulling is popular, but there is no good evidence that it whitens teeth.
• Whitening toothpastes can lift light surface stains but don't change the natural shade of your teeth.

Professional teeth whitening

Professional whitening uses carefully controlled peroxide-based gels to lighten the shade of the tooth itself, not just surface stains. The dentist first checks that your teeth and gums are healthy, protects the gums, and monitors the process, which makes it safer and more predictable than unsupervised kits.

Who should wait?

• Anyone with untreated cavities or gum disease. These need treatment first
• People with very sensitive teeth, who should discuss options with their dentist
• Pregnant or breastfeeding women, who are generally advised to postpone
• Anyone with crowns, veneers or fillings on the front teeth. They don't whiten, so shades may not match afterwards

Keeping your results

Rinse with water after tea, coffee or cola; use a straw for dark drinks; avoid tobacco; brush twice a day; and keep up with professional cleanings. Results can last from several months to a couple of years, depending on your habits.
