The most significant effect of drug and alcohol abuse on the teeth is the apathy of the addict towards dental hygiene.

smoking aint exactly a picknick on your teeth either. Engage in that activity at your own risk.

I've seen a few patients who had been on meth or cocaine who really ground their teeth down to nothing. It is very distinct. Alcoholics also have very distinct mouths.

Isn't cocaine sometimes used for dental surgery?

"The effect of methamphetamine is so severe that it has its own term: "Meth-mouth." Frequent users of the drug experience a sudden, massive onset of tooth decay, gum disease and worn down teeth."

As a public defender I represent so many hardcore meth addicts and most all of them have terrible teeth. I can usually spot the meth heads when they show up at first appearances in their orange jail suits as soon as they open their mouths to talk to me. It's in the teeth and/or that certain "spun" look they usually have in their eyes and their mannerisms. That stuff is poison.
