Discoloured Teeth

Discoloured Teeth - Causes and Risk Factors

​Discoloured teeth can be caused by:

  • Chromogenic (stain forming) bacteria, which reacts with certain foods you eat or your saliva to create black stains on your teeth
  • Coloured compounds found in foods and drinks (eg. coffee, tea, red wine, colas, curries)
  • Disturbance during the tooth formation from
    • medication or chemicals e.g. tetracycline, excessive fluoride consumed during the tooth formative years
    • illnesses that affect tooth development e.g. high fevers, metabolic disorders
  • Genetic factors
  • Natural aging of teeth
  • Poor oral hygiene
  • Root canal treatment - teeth which no longer have a functioning pulp will change its colour after some time
  • Trauma to the teeth
  • Tobacco use
  • Tooth decay (caries)
