Are Cavities Contagious?

WE ALL KNOW it’s possible to catch a cold from someone who’s under the weather. Did you know cavity-causing bacteria can be passed from person-to-person too?

Bacteria Is At The Root Of Cavities

While sugary treats often take the blame for causing cavities, the real culprits for tooth decay are bacteria. Streptococcus mutans and Streptococcus sobrinus are bacteria which stick to our teeth and eat food particles left behind from our last meal, producing acids which threaten gum health and cause tooth decay.

And just like cold-causing bacteria, these bacteria like to travel.

Bacteria Travels From Person-to-Person

Whether it’s through sharing a drink or kissing a loved one, cavity-causing bacteria can be passed from person-to-person the same way many other bacterial infections can. Studies have shown that “catching a cavity” is not only possible, it happens far more often than you might think.

One of the most common transmissions is from parent and child. Cavity-causing bacteria is commonly passed along to a child when a mother or father tastes food to ensure it’s not too hot or when he or she “cleans” a pacifier by sucking on it before handing it over.

Take Simple Steps To Stop The Spread of Bacteria

What can you do to reduce your risk of transmitting these cavity-causing bacteria to someone else?
Floss and brush frequently.
Chew sugar-free gum—this promotes saliva production and washes away plaque and bacteria).
Be mindful of drinks and eating utensils you’re sharing and the risks that are involved.
Be aware of other behaviors which may spread these bacteria.
