Milky teeth are only made to function for a limited time, enamel is thinner than for adult teeth. Dentine canals are widely opened enabling caries bacteria to enter. Small lesions can also be applied to milky teeth but sticking ability is reduced. Bigger defects can be treated with vital-amputations (partial preservation of dental nerves). Devitalized or fistulous milky teeth ought to be removed for protection purposes of the tooth germ.
