What Can Cause Teeth to Become Discoloured?
Tooth colour can change for several reasons. Some staining develops gradually as part of the natural ageing process, while other types are linked to lifestyle habits.
Common causes include:
Coffee and Tea
Regular consumption of coffee and tea can contribute to surface staining over time. These drinks contain compounds that can attach to the tooth surface and gradually make teeth appear darker.
Food and Drink
Certain foods and drinks, including deeply coloured sauces, berries and red wine, can contribute to staining, particularly when consumed frequently.
Smoking
Smoking and tobacco use can cause noticeable staining and discolouration of the teeth.
Ageing
As you age, the outer enamel layer can naturally become thinner, allowing the naturally darker dentine underneath to become more visible.
Previous Dental Treatment
Whitening affects natural tooth structure, so existing fillings, crowns, veneers and other restorations may not change colour in the same way as natural teeth.
Your dentist can discuss this with you before treatment so you have realistic expectations about the final result.
