tardive dyskinesia
You may be quite right.
Tardive dyskinesia is a side effect of antipsychotic medications. These drugs are used to treat schizophrenia and other mental health disorders.
TD causes stiff, jerky movements of your face and body that you can’t control. You might blink your eyes, stick out your tongue, or wave your arms without meaning to do so.
is there a dentist who can comment? it surely looks as if she is licking her teeth, as if she feels necessary to clean particles of food stuck between her teeth. and to a neurotic degree. i am wondering about dentures.
