Tooth Discolouration:
Causes, Symptoms and treatments

Tooth discolouration can manifest as yellowing, dark spots, or a reduction in brightness, affecting the aesthetic appeal of the smile. While some individuals naturally have whiter teeth, others may experience discolouration due to various external and internal factors. At Thames, Dr Bravis and her specialist team provides advanced dental treatments tailored to address tooth discolouration and associated symptoms effectively.

Symptoms and causes

Discoloured teeth can result from various factors, including:

Extrinsic causes: Staining of the enamel due to factors like:

  • Consuming certain drinks such as coffee, tea, or red wine
  • Food containing turmeric
    Constant drinking of lemon water or fruit juices
  • Smoking or chewing tobacco
  • Poor dental hygiene leading to tartar buildup


Intrinsic causes: Darkening of the internal tooth (dentine) due to reasons like:

  • Ageing, which causes enamel wear and exposes the darker dentine
  • Overexposure to fluoride during childhood (fluorosis)
  • Root canal treatment
    Dental trauma or untreated traumatised teeth
  • Antibiotic treatment in childhood, like tetracycline
  • Certain enamel conditions like amelogenesis imperfecta
