I think one of the big arguments about toxicity rests with the accumulative dose when flouride toothpaste, mouth wash and so forth are taken into account.
Even so, the amount needed to create flouride overdose...you'd basically need to be eating the toothpaste, as I understand it.
This is a more important debate than ever imo, with some of the recent studies seeming to show a causal link between toothdecay and some types of heart disease.
