I don't think I've ever seen or heard of someone having teeth that were discolored reddish-purple. What could cause that?

''Early Antibiotic Exposure
Exposure to the antibiotic
tetracycline while in the womb or as a young child causes discoloration in adult teeth. Affected teeth develop blue-gray or yellow-brown stains, often in a pattern of horizontal stripes.''

The Discolouration of Human Teeth from Archaeological Contexts: Elemental Analysis of a Black Tooth from a Roman Cranium Recovered from the River Witham, Lincoln, UK
''A number of metabolic and congenital conditions cause human teeth to become discoloured; for instance, fluorosis causes brown staining of the teeth and purple staining of the gums, whilst
congenital erythropoietic porphyria can produce red-purple dentition [1, 2]. Discoloured dentition is also associated with some occupations—most notably workers in the metal industry, where a variety of staining has been reported [3, 4]. Certain habits, such as smoking and chewing tobacco and drinking coffee, are known to cause yellow-brown discolouration of dentition [5, 6], whilst
chewing betel nut produces a deep red staining of the dentition and oral mucosa [7]. Some drug treatments are also known to cause dental discolouration; for example, the antibiotic tetracycline is well documented as causing black discolouration of dentition [8, 9].'
''When
the blood supply to
a tooth is interrupted, either temporarily or permanently, hemoglobin in
the pulp cavity is degraded into byproducts that leach into
the dentin wall and give it
a pink or
purple hue. If these hemocomponents continue to break down,
the tooth will appear blue or gray.Mar 29, 2017'
