Cavities are caused by bacteria so they have to be faced as a disease and not as isolated facts.
The first thing to do is treat every cavity in your mouth because each cavity is going to ruin not
only the tooth but also will contaminate the saliva with cariogenic bacteria that can and will affect
other teeth.
A proper brushing and flossing technique to daily eliminate plaque is very important as well as
eating a diet poor in sugars.
