Are Cavities Contagious? A complete GUIDE....

1. Can cavities be spread from one person to another? Yes, cavities are technically contagious. The bacteria responsible for cavities, particularly Streptococcus mutans, can be transmitted through saliva by activities like sharing utensils, kissing, or even blowing on food. 2. How do cavity-causing bacteria work? These bacteria feed on sugars in the mouth, producing acid that erodes tooth enamel, leading to cavities. Once transmitted, they can colonize another person’s mouth if oral hygiene is inadequate. 3. Can children catch cavities from parents? Yes, parents can pass cavity-causing bacteria to children through saliva-sharing activities, such as testing food temperature or sharing utensils. 4. How can you prevent cavities from spreading? Maintain good oral hygiene, avoid sharing saliva, and limit sugary foods. Regular dental visits are crucial for early detection and management of cavities.
