Thank you very much for doing the math! That really does put it into perspective.

I was assuming you would still be absorbing the lead through your gum line and sublingually through the glands under your tongue into your bloodstream even without swallowing any, but that does sound like extremely low quantities.

For me personally, I have ADHD and a bad memory so anything I can do to mitigate exposure to lead to lessen my chance of developing Alzheimer’s or Dementia as I get older seemed like an obvious decision especially when the solution is to just get a low abrasion toothpaste that doesn’t include these potentially contaminated abrasive materials.
