There are many factors that can contribute to tooth staining. Some of the reasons are listed below:
- Foods/Drinks: Coffee, tea, wines and intensely coloured foods.
- Smoking: Smoking or chewing tobacco.
- Poor dental hygiene: Inadequate brushing and flossing.
- Ageing: As you get older the outer layer of enamel on your teeth wears away. Furthermore the older you get the more tar tar and stains accumulate on your teeth causing them to darken and discolour.
