Are Dental Cavities Contagious?


Many parents are shocked to learn that their children have dental cavities even though they practice flawless dental hygiene! However, even the best oral hygiene routine can fail if you’re sharing the bacteria that cause tooth decay and dental cavities.

Stop Sharing Cavity-Causing Bacteria

It’s been found that 80% of all dental cavities occur in only 23% of kids. This means that children with a tendency to share bacteria can develop multiple cavities. Below are a few ways to prevent the sharing of cavity-causing bacteria:

  • Never share toothbrushes – As obvious as this one seems, it does happen. Each member of your family needs to have his or her own toothbrush. Toothbrushes should be replaced every 4-6 months, or once the bristles start to fray. 
  • Never share utensils – It’s common to share bites of food in the same family, especially young kids. We suggest keeping utensils separate to decrease the risk of spreading germs and bacteria. 
  • Never share infant pacifiers – If there’s more than one toddler in the house, it’s common for them to swap pacifiers or use them interchangeably. Keep pacifiers separate and clean them frequently with warm, soapy water. 
  • Set a good example for your kids – The best way to make sure your kids practice good dental hygiene is to care for your own teeth. You should be brushing and flossing each day and visiting the dentist every six months for a dental cleaning and a checkup. When your kids watch you caring for your oral health, they’ll be more likely to prioritize their own.
