Among the wealthy lesser nobles, and merchants of the larger cities golden and silver mouth jewelry is becoming very prominent. While not so much with the older people the youth with too much coin and time have worn them as status symbols.
Jewelers who were one charged with making ornate works for upper class nobility had been given huge sums of coin to produce these mouth adornments. They take some time to make and are unique to each wearer. Younger jewelers who would have to wait their whole lives to produce something of note are building strong reputations right away.
Culturally this has been received poorly in Helios. The masses see it as a decadence, and a flaunting of wealth that even the High Court Nobles, who wielded the wealth of the nation did not do.
