A tooth left in a glass of Coca-Cola will not dissolve overnight.
In 1950, Professor Clive McCay of Cornell University told a select committee of the US House of Representatives that the high levels of sugar and phosphoric acid in Coke caused tooth decay. To dramatise his testimony, he said that a tooth left in a glass of Coke would begin to dissolve after two days. Even if McCay’s claim were accurate (those who have tried the experiment say it’s not), it's irrelevant. Nobody holds Coke in their mouths for two days, not even people who really like it, and the acids it contains are dealt with by the digestive system.
Many common foods are more acidic than Coke. Of course, it’s generally agreed that sugary drinks can cause tooth decay, but they do so gradually. Nonetheless, the tooth-in-Coke story is still widely believed - perhaps because of its impressive origins.

In the late 19th century, the mouse started bringing gifts – the child would put the lost tooth in their shoe, and the mouse would exchange it for a coin.
