Are cavities contageous?

Question

My son has a small cavity, and I'm worried about it spreading to me or my husband. Can cavities actually be contageous?

Sarabjit Kaur · Accepted Answer

Actually, the bacteria that cause cavities can be passed on, especially between parents and kids if we share spoons or blow on their food. I was so surprised when our paediatrician told us this! It's best to keep utensils separate for safety.

Wait, does this mean I can't share my dessert spoon with my friends anymore? Technically, the bacteria can spread, but poor brushing and eating too many sweet treats are the real culprits. Just enjoy your food but clean your teeth well!

It is true that cavity-causing bacteria can spread from person to person. I had severe gum complications and my doctor warned me about sharing utensils with family. Please see a dentist to understand your risks properly.

Scientifically, yes, Streptococcus mutans is the bacteria responsible and it can be transmitted via saliva. I track my health metrics daily and love reading up on this. Just maintain good oral hygiene and you'll keep the risks very low.

Yes, the mouth bacteria can transfer through saliva, though the cavity hole itself doesn't jump over! The most practical solution is to avoid sharing drinking glasses and ensure everyone in the house brushes twice a day.
