About Fluoride
Fluoride makes tooth enamel more resistant to the acid that causes decay. The body also takes it into bone.
Most dietary fluoride comes from drinking water, particularly where the supply is fluoridated, and from tea, because the tea plant concentrates it. Figures for prepared foods and drinks depend heavily on the water they were made with. The UK label reference intake is 3.5 mg a day.
Too much fluoride while teeth are still forming in childhood can cause dental fluorosis, faint white marks on the enamel. That is why young children are advised to use only a smear or a pea-sized amount of fluoride toothpaste.

Per calorie is the default here because it answers what to eat: ranked purely by amount, a list of the richest foods fills up with dried and concentrated things nobody eats a plateful of. Switch to per 100 grams above if concentration is what you are after.
