Are you born with the bacteria that causes cavities?

I just got my first cavity filled, and it got me thinking. My dentist always stresses on oral hygiene, but are we actually born with the bacteria that causes cavities, or do we pick it up later?

Actually, babies are born without Streptococcus mutans, the main cavity-causing bacteria. They usually catch it from caregivers through sharing spoons or kissing. Since my own health journey with PCOS, I try to be very careful with health facts, so checking with a dentist is always best.

Nahi bhai, bachpan se nahi hota hai ye. It comes when we feed kids sweet things and don't clean their mouth properly. Just make them brush twice a day and don't let them sleep with milk bottles in their mouth. Simple habits keep teeth strong!

No beta, newborns have clean mouths. They get these germs later from adults. In our times, we made children rinse their mouth with warm salt water after every meal to keep germs away. Still, if there are cavities already, please show them to a dentist.

No, it is transmitted after birth, typically during the first year of life. Since dental health can affect overall health, it is very important to get regular dental cleanings and checkups for your family instead of trying to treat cavities at home.

You are not born with it, babies get it from sharing food or utensils with parents. I didn't know this and let my baby share my spoon, which led to early childhood cavities and a painful dental surgery. Please visit a pediatric dentist early to keep their teeth safe.

I totally get it, it sounds so weird that we aren't born with it! We actually catch this bacteria during infancy, mostly from our mothers or family members. It's nothing to feel guilty about, but it shows how important early oral hygiene is for kids.
