Contagious Cavities?

Nov 23, 2015

Question: Can cavities be spread through saliva?

Sharing Drink

Answer: Yes! Bacteria that causes cavities is contagious and can be spread through the saliva.

As said by the American Academy of Pediatric Dentistry, “It’s likely common knowledge that illnesses such as the flu and the common cold are contagious. But many parents might be surprised to find out the bacteria that causes cavities is also contagious, and can be passed along through saliva! As a parent or caregiver, this is important to keep in mind when going about your day with your little one. It’s best to avoid activities such as sharing a plate or blowing on your child’s food in order to help prevent sharing saliva that might carry cavity-causing bacteria. While it’s important to be aware of this, remember, the number one way to prevent cavities is to brush and floss each morning and night. Don’t forget to supervise your little ones during these daily dental routines until they are seven or eight years of age, or able to tie their own shoes, in order to ensure healthy little teeth.”
