meth mouth
n.— «Methamphetamine seems to be taking a unique, and horrific, toll inside its users’ mouths. In short stretches of time, sometimes just months, a perfectly healthy set of teeth can turn a grayish-brown, twist and begin to fall out, and take on a peculiar texture less like that of hard enamel and more like that of a piece of ripened fruit. The condition, known to some as meth mouth, has been studied little in dentistry’s academic circles.» —“Grisly Effect of One Drug: ‘Meth Mouth’” by Monica Davey New York Times June 11, 2005.
