Yellowing of teeth is a common concern, but the reasons behind it are often more surprising than most people realize. While habits like drinking coffee or tea are well-known contributors, many other factors can affect the colour of your teeth over time. Natural ageing, enamel thinning, certain medications, poor oral hygiene, smoking, and even underlying dental conditions can cause teeth to appear dull or yellow. In some cases, internal staining from trauma or excessive fluoride exposure during childhood may also lead to long-lasting discoloration that cannot be corrected with regular brushing alone.
