Right. Although we do consume some toothpaste via what's leftover in the mouth after brushing, I'd expect you'd have to have quite high concentrations in the toothpaste to be of any concern. We probably ingest more lead via air pollution and in our food than via this vector, though it would have to be properly studied to be sure, assuming it hasn't been already. This study in particular seems to have some flaws.
