Of course very good dental health is largely because of oral hygiene habits, but diet likewise plays a huge part. I will discuss here the task of food and our eating habits in maintaining nourishing teeth and gums. Past exploration was insufficient, in that it primarily stressed the chemistry of nutritional requirements in causing cavities, like the effects of the kind of food eaten up and also the initial results of food while still in the mouth. There are, social, humanistic, however, and environmental factors linked to dental health that also have to be considered.
