For those who are "laughing" at people who have concerns about fluoride -- get something into your head!

Sodium fluoride is a deadly poison.

Spend a little time researching how much it takes to kill an adult human; then start calculating how many tubes of tooth paste or gallons of tap water it takes to accumulate a lethal dose.

(If you do that research, and have young children around the house -- and have half-a-brain -- you'll treat your tooth paste the same way you treat prescription and over-the-counter medicines.)

Heck, just read the label on your toothpaste and ask yourself why it says to "contact your poison control center immediately" if ingested in a quantity larger than that used for brushing your teeth?

The risks from sodium fluoride is not something to laugh about; whether you're talking about ingesting a potentially lethal dose or ingesting small amounts supposedly to "help" your teeth.
