Most people don’t realize that cavities can actually spread from one person to another. While cavities themselves aren’t contagious, the bacteria responsible for them—especially Streptococcus mutans—can be transmitted through saliva. That means simple acts like kissing, sharing spoons or forks, or even blowing on a baby’s food can transfer these harmful bacteria from one mouth to another.

Once these bacteria colonize a new mouth, they begin to feed on sugars from food and produce acids that damage the tooth enamel, leading to cavities over time. This is especially important in young children, whose enamel is softer and more vulnerable. Parents, caregivers, and partners should be aware that oral hygiene affects not just themselves, but their loved ones too.

The best way to prevent this transmission is to maintain good oral hygiene, limit sugary foods, and avoid sharing utensils or toothbrushes. Regular dental checkups and cleanings also help reduce bacterial load and prevent decay. A healthy mouth is not only about brushing—it's about protecting those around you as well.
