Erythropoietic Porphyria

• "Congenital Pink Tooth"
• Occurs in cattle, cats and sometimes pigs
• Teeth are pink due to congenital inability to metabolise haemoglobin pigments. These pigments also produce photosensitivity in skin.
• This results in severe sunburn if animal exposed to normal levels of sunlight.

Discoloration of a single tooth is more likely to be caused by pus in the tooth.
