"other drugs" Im gonna go with heroin on this one. Might be meth mouth, but shes so fucking fat. Heroin and methadone are known to leach calcium out of the teeth. Causing that weird teeth shape, combined with the dry mouth effects you get terrible gums, color, and your teeth start shrinking. One of the easier ways to identify an addict tbh, even pregnancy wont do that to your teeth, alcohol, meth and heroin will though.
