Is tooth decay contagious?

User Level:

Posted by: laguy821  (1 year ago)
Tooth decay can in fact be contagious. Decay results from acids caused by bacteria in the mouth, and these acids can be transferred as a result of kissing, sharing utensils, or any activity that results in an exchange of saliva. This is just one of the reasons why it’s so important to brush your teeth at least twice daily and maintain good oral hygiene.

If this is true, we should start worrying about other people's dental care before kissing someone! :-)

Bacteria can be transferred mouth to mouth, but bacteria need a substrate to produce acid. It is the frequent ingestion of sodas and sweets that give bacteria the substrate the substrate to produce lactic acid.

Passing bacteria mouth to mouth is probalby more of an issue with gum disease than caries.

Yes, Tooth decay can be contagious. As discussed above, reason of decay is acids caused by bacteria in the mouth.
It can be transfer form one person to another.
So we should adapt some preventive measures to control it like:
Do not share your toothbrush.
If you know a person has decay then don't share same cup or glass.
newborns baby get most effect due to this. So, adapt these measures strictly if you have a new born baby
