Do your teeth still look yellow even though you brush them regularly?
You're not alone. Yellow teeth don't necessarily mean your teeth are unhealthy or that you're not brushing properly. Tooth colour can change for several reasons, including natural tooth colour, staining, age, and lifestyle habits.

Why Are My Teeth Yellow?

Natural Tooth Colour
Not everyone's teeth are naturally bright white. The inner layer of a tooth can have a naturally yellowish colour that becomes more noticeable as enamel changes over time.
Food and Drinks
Coffee, tea, red wine, and other strongly coloured foods and drinks can contribute to surface staining.
Smoking and Tobacco
Tobacco can cause noticeable staining and discolouration over time.
Aging
As you get older, enamel can naturally become thinner, making the naturally darker layer underneath more visible.

Can Brushing Make Yellow Teeth White?

Brushing twice a day is essential for keeping your teeth clean, but brushing alone may not remove deeper or long-standing stains.
Professional cleaning can help remove certain types of surface buildup and staining. For a brighter smile, professional teeth whitening may be an option depending on the cause of the discolouration.

Can Whitening Fix All Yellow Teeth?

Not necessarily.
Whitening works best on certain types of stains and may not change the colour of fillings, crowns, veneers, or other dental restorations.
A dental professional can examine your teeth and help determine whether whitening is likely to give you the results you're looking for.

How Can You Prevent More Staining?

You can help maintain a brighter smile by:

• Brushing twice a day
• Cleaning between your teeth daily
• Keeping up with regular dental cleanings
• Limiting frequent staining foods and drinks
• Avoiding tobacco products

The Bottom Line
If your teeth look yellow despite regular brushing, it doesn't necessarily mean you're doing something wrong.
The colour may be natural, or staining may have developed over time. A professional dental assessment can help determine what is causing the discolouration and which options may improve your smile.
