🦠Did you know cavities can be contagious?🦷
Cavities aren’t just about sugar. They’re caused by bacteria. And yes — those bacteria can actually spread from one person to another.
Everyday habits like kissing, sharing spoons, straws, or even putting a baby’s pacifier in the mouth can pass cavity-causing bacteria. The main culprit is Streptococcus mutans, which stick to teeth and produces acids that damage enamel.
Saliva is full of bacteria — some good, some harmful. When two people share saliva, the cavity-causing bacteria hitch a ride in those tiny droplets. Once they reach a new mouth, they attach to the tooth surface, especially where plaque already exists. If sugars are present, these bacteria quickly start producing acid, which weakens enamel and leads to cavities over time.
👶 Babies and young children are most vulnerable. Their teeth are still developing, and once these bacteria settle in, the risk of early cavities skyrockets. That’s why parents with untreated tooth decay often see their kids struggle with cavities too.
😬 Adults can spread it as well, but strong habits like daily brushing, flossing, less sugar, and regular dental visits make a big difference. The bacteria may transfer — but they don’t stand a chance if your mouth is protected.
