I'd rather not try -- there's scientific controversy and the explanations on both sides (that I've seen) are low quality. So people are reduced to 'weighing evidence', which is irrational. Part of the problem of course is politics. Dental health and vaccination are both very important good things and this makes it even harder to determine the truth of the matter. For example, people regularly exclaim things like 'there's absolutely no evidence that X', or 'there's overwhelming evidence that Y'. But they do this rhetorically, and as I said, without associated explanations. In such circumstances 'evidence' isn't always meaningful. Hence my original point. Since we don't yet understand how the brain and the mind work (if we did, we'd have AGI) we're not in a position to assess damaging effects, if any, which may be subtle. If this was any other organ, I'd say let it go. But the brain is the seat of the mind and is therefore uniquely precious.
