Discoloured teeth - teeth may be amber, brown, blue or opalescent; Bulbous shape to the tooth crown due to cervical constriction; Tooth wear/Non-carious tooth surface loss (NCTSL) - due to the poorly mineralised dentine, the enamel of the tooth is unsupported and subsequently shears or chips off as it is subjected to biting forces. This exposes ...
