Just to correct more BS I see going around this morning:
It is important to clarify the differences between sodium fluoroacetate (compound 1080) and the fluoride found in toothpaste and other oral care products.
Sodium fluoroacetate (1080) is indeed a potent rodenticide and herbicide. It is highly toxic to mammals, including humans. However, this compound is different from the fluoride used in dental care products.
Fluoride, in the form of sodium fluoride, stannous fluoride, or sodium monofluorophosphate, is a common ingredient in toothpaste and oral care products. It is an essential mineral that helps strengthen tooth enamel and prevent tooth decay. The concentration of fluoride in toothpaste is generally safe for humans when used as directed, which involves spitting it out after brushing and not swallowing it. In extremely high amounts, fluoride can be toxic, but the levels present in dental care products are far below those that pose a risk.

@TomWellborn @skry The systemic fluoride provided by fluoridated drinking water has little positive effect wherever basic dental care regimen is maintained, and poses considerable long-term health risk to people with endocrine problems, especially hypothyroidism. Water is too vital a substance to render unusable or silently dangerous for a significant section of population by dosing it with medical or nutritional products that address questionable concerns.
