There are many factors that affect tooth decay and plaque buildup including the microbial content of your mouth, your diet, and the amount of saliva produced.

There are many factors that affect tooth decay and plaque buildup including the microbial content of your mouth, your diet, and the amount of saliva produced. But one thing that is clear is that oral health is very important. I've noticed that when I brush around midday, I'm in a much better mood. But don't take my word for it -- numerous studies have established co-incidence between heart disease, mortality, and inflammation and bad oral health. And there are good reasons to believe it is not simply an issue of correlation without causation as local even mild infection can cause many downstream effects throughout the body. And anyways, it's just so much better to have a clean mouth.
