Bottle decay in children refers to the rapid decay of teeth caused by prolonged exposure to sugary liquids, typically from bottles or sippy cups.

When children are consistently given sugary drinks like juice, milk, or formula in bottles over an extended period, the sugars can coat their teeth, providing fuel for bacteria to produce acids that attack the enamel.

Bottle decay can have serious consequences for a child's oral health, leading to pain, infection, and even tooth loss if left untreated.
