The enamel is fragile, the teeth appear yellow or brown, and surface stains build up more readily. [1] Dentinogenesis imperfecta is a defect of dentin formation, and the teeth may be discolored yellow-brown, deep amber or blue-grey with increased translucency. [1] Dentinal dysplasia is another disorder of dentin.
Permanent (adult) teeth are not discoloured, or the discolouration is mild (grey colour). Little or no attrition (tooth wear) is evident. The crown of the teeth may be bulbous and markedly constricted at the cemento-enamel junction (CEJ). Radiographically, evidence of partial pulp obliteration with a "thistle-shaped appearance". [3]
Amalgam tattoo is a grey, blue or black area of discoloration on the mucous membranes of the mouth, typically on the gums of the lower jaw. It is a healthcare caused lesion, due to entry of dental amalgam into the soft tissues. It is common, painless, and benign, but it can be mistaken for melanoma

Since 1920, various derivatives of "chalky teeth" have appeared in the academic literature to describe specific dental anomalies. Most references are to enamel defects that have a chalky appearance (white, cream or brown) and are of developmental origin (i.e. amelogenesis imperfecta, enamel hypomineralisation, dental fluorosis, molar hypomineralisation).
