China's Candy Repairs Your Teeth While You Sleep What?

The product mentioned is likely referring to a recent development in biotechnology where researchers have been exploring the use of certain compounds to repair tooth enamel or remineralize teeth. This could involve the use of peptides or other molecules that help in the repair of early stages of tooth decay or enamel damage. Such products are not 'candy' in the traditional sense but rather a form of oral care product that might be sweetened or flavored to make it more palatable. It's essential to understand that any such product would need to undergo rigorous testing for safety and efficacy before being approved for consumer use.
