Dental caries can be transmitted from person to person

Dental caries was long considered a purely individual problem—a person's gums and teeth were destroyed by bacteria left behind after eating. However, recent research shows that this disease can be contagious. American scientists from the University of California have discovered that the bacteria that cause dental caries can be transmitted between people like influenza viruses.

The main causative agent of dental caries is Streptococcus mutans. These bacteria actively multiply in the mouth, producing acid that gradually destroys tooth enamel. Children are especially vulnerable: their teeth are more easily attacked by bacteria, and their immune systems are not yet fully developed.

Children can contract dental caries from parents and close friends. For example, transmission is possible through shared spoons, pacifiers, or kissing. Even a small number of bacteria can take hold in the mouth and gradually begin to destroy teeth. Therefore, oral hygiene in adults directly affects the health of children.

To reduce the risk of infection, dentists recommend meticulous oral hygiene. Regular brushing, flossing, and chewing gum help reduce bacteria. It's also important to avoid sharing cutlery and utensils with children.

This research calls for a new approach to caries prevention. The bacterial nature of the disease makes precautions especially important in families with small children. Adults need to not only treat their own teeth but also prevent the transmission of infection.

The discovery that caries is contagious has already sparked widespread concern among dentists. The fight against caries now includes not only treating and strengthening enamel but also maintaining good personal hygiene to protect loved ones from this hidden infection.
