What causes internal staining of developing teeth?
• Internal staining can be caused by the following: • Abnormal tooth development can cause staining. • Childhood illnesses during tooth formation can cause mottled stains. • An excess of fluoride while teeth are developing can cause fluorosis, seen as a whitish-brown mottling of the tooth. • Injury or infection of a baby tooth may lead to discolouration of the permanent tooth that replaces it. • Tetracycline medication can cause creamy brown staining.
