Meth Mouth
Meth mouth is unlike any other drug, candy or vice in most dentists'
memories. 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 a piece of over
ripe
fruit. The condition, known to some as "meth mouth," has been studied
little in academic circles and is unknown to many urban and suburban dentists,
whose
patients are increasingly focused on cosmetic issues, the bleaching and perfect
veneers of television's makeover shows. But other dentists, especially those
in the open, empty swaths of land where methamphetamine is being manufactured
in homemade laboratories, say they are seeing a growing number of such cases.
With the exception of a few formal studies, including one beginning in New
Mexico, meth mouth has so far been less a topic of academic analysis in the
dental industry than a matter for casual phone conversations and e-mail exchanges
between dentists in small places. "The truth is, very little is known yet," said Dr. Stephen Wagner,
who specializes in dentures and implants in his private practice and who will
be studying 20 afflicted patients with Tatlock in the coming months at the
University of New Mexico. "What I can tell you is what I have seen: It
looks like someone has taken a hammer to these teeth and shattered them."
Dry mouth, one immediate cause of meth mouth, is the result of depleted saliva
glands, easily exacerbated by the acidic nature of the drug when smoked or
snorted.
Meth is made from hydrochloric acid. When users smoke meth, the acid in the
drug erodes their tooth enamel. The drug also leaves users dehydrated and craving
sweets. Add up a loss of tooth enamel, a constant sweet tooth and a disregard
for brushing, and you end up "meth mouth" with teeth that are little more than
little black
stubs.
Just how meth destroys the mouth so spectacularly is a matter of scientific
debate. But Stein and others describe a "perfect storm" under way
once users start smoking or snorting meth, a potent stimulant.
With meth vapors bathing the teeth in the acidic chemicals used to make the
drug, the mouth dries up, stopping the flow of protective saliva. When that
happens,
oral bacteria explode - up to tenfold above normal levels, Stein said, setting
the stage for severe, fast-moving decay. "To complicate all this, the meth user
tends to crave sugary drinks, the
perfect food source for the bacteria," he said.
" Making matters worse is the high anxiety and paranoia meth causes - people
start grinding and clenching their teeth. When teeth literally begin to crumble,
it's often too late to save them."
Meth cavities usually start between two teeth,
moving
from
cuspid to cuspid across the network of enamel. Also, the desire to grind
one's molars together can easily result in multiple teeth snapping right
out of
the meth user's mouth. The meth mouth epidemic is widespread
in prisons
as well, where clean, sharp teeth are not always valued. Prisons are now
obligated to devote a growing portion of their health-care budgets to emergency
dental care, which costs taxpayers in every state a small fortune each
year.
