Why are my teeth yellow even though I brush every day?

Tooth colour comes from inside the tooth, not just the surface. Thinning enamel and naturally thickening dentine make teeth look warmer and darker over time, even with excellent brushing.

Why do teeth get more yellow as we get older?

Enamel becomes thinner and more translucent with age, while dentine becomes thicker and more yellow. Together, this makes teeth naturally look darker and more yellow.

Can whitening fix naturally yellow teeth?

Yes. Professional whitening brightens both enamel and dentine, improving age-related yellowing. Older dentine may take longer to lighten, but supervised whitening remains highly effective.

Is yellow tooth colour always staining?

No. Yellow shades often come from dentine, which is naturally warm in colour. Surface staining from foods and drinks affects enamel, but deep tooth colour is determined by dentine.

Can enamel grow back if mine is thin?

Enamel cannot regrow, but its optical effect can be restored with whitening, composite bonding, or micro-layered veneers. These treatments safely restore brightness and light reflection.

What shade should my teeth be naturally?

Most adults naturally fall between A2, A3, and B2–B3. The ideal aesthetic guideline is that your teeth should be slightly lighter than the whites of your eyes.

How white is too white?

If teeth become brighter than the sclera, they can appear artificial and overly opaque – the 'Turkey Tippex white' effect. Natural whiteness has balance and translucency.

Why do the edges of my teeth look see-through?

This is enamel translucency. As enamel thins, the edges reflect less light and appear grey or glassy. Whitening or bonding can restore the appearance.

Why are my teeth different colours?

Teeth may differ in colour due to variations in enamel thickness, ageing restorations, trauma, or conditions like fluorosis, MIH, hypoplasia, or tetracycline staining. These can be blended or corrected with cosmetic treatments.
