By the 1970s, both sugary toothpaste and Teflon frying pans were out – considered a problem rather than a solution. In the first case, the verdict was voiced by dentists. In the second, science suggested, among other things, that the fluorinated coating could be toxic when overheated.

But now, putting two and two together – toothpaste and Teflon – there seems to be good news, both for chefs and for children. According to a UK research team writing in the Journal of the American Chemical Society, its newly found treatment process breaks apart the plastic’s strong carbon-fluorine bond and allows the components to be converted into a protective toothpaste fluoride or added to drinking water.
It’s a circular solution both eco-friendly and inexpensive, the team says. One that the households of the 1950s could never have dreamt of.
