Yellowing teeth are one of the most common smile complaints. The good news is that most discolouration responds well to treatment once you know the cause.
Teeth turn yellow from surface stains (coffee, tea, tobacco, red wine), thinning enamel that reveals the yellow layer beneath, and ageing. Surface stains respond very well to professional whitening; deeper discolouration may need veneers or bonding. Good daily care and cutting staining habits keep teeth bright.
Common causes
- Staining foods and drinks - coffee, tea, red wine, dark sauces.
- Tobacco - a major cause of stubborn yellow-brown stains.
- Thinning enamel and ageing - revealing the naturally yellow dentine beneath.
- Poor cleaning letting plaque and stains build up.
What actually works
- Professional whitening - the safest, most effective way to remove surface and many deeper stains. See our whitening guide.
- Regular cleaning to remove stain-holding tartar.
- Veneers or bonding for discolouration that will not whiten.
- Cutting staining habits and rinsing after coffee or tea.
Keeping teeth white
After whitening, six-monthly cleanings and good habits keep results lasting. Book a brightness assessment at The Tooth Studio.
