This is a silly urban legend. Please note:
All such claims ignore a few salient points. A glass pf coke can’t dissolve a tooth or a nail, or a penny, or a piece of meat overnight. It contains acids such as citric acid and phosphoric acid which will eventually dissolve items such as teeth given enough time than one night, but so do plenty of other substances we commonly ingest such as orange juice. The concentration< of acid in these products is so low that our digestive systems are easily capable of coping with it with no harm to us. The idea that any substance which can dissolve teeth must therefore damage our teeth if we drink it is nonsensical. We don’t hold drinks in our mouths for days at a time — any liquids we drink simply wash over our teeth very briefly, and our teeth are further protected by their enamel coating and the ameliorating effects of saliva and the mucous membranes in our digestive system.
