Cyanide is famously deadly, yet you eat it every time you eat an apple. Concentration matters.
Table salt would also kill you if you ate 1cup/2,5dl of it in one sitting.
The fluoride concentration in tap water is like 0.7mg/l. Toxic dose is 60 mg/kg, but 0.2 mg/kg is enough to cause some gastrointestinal discomfort. If I chug 16 liters of tap waters after I brushed my teeth I'll have some gastrointestinal discomfort from fluoride but I'll probably die from water poisoning first.
