I heard that if you kiss someone with cavities that you will get them as well. I doubt this is true, is it?
Question:
Answers:
I'm a Dental Hygienist and I went to a CE meeting that said the bacteria that causes decay IS contagious and not hereditary! So your friend may be right. Don't share drinks, this is the biggest way this bacteria is passed. Also sugar, esp. soda, feeds this bacteria and it doesn't live long. When it dies it releases an acid that causes the decay, eats away the enamel.
One way to kill this bacteria is a substance called xylitol, which is a sugar found in many gums including carefree Koolers and some trident.
no you cant. Its impossible
