What is Plaque and why does it cause Cavities?

Whatever food and drinks we consume throughoutthe day, do not end up in our stomachs.  Some of these little food particles get embeded in our teeth and gums.  These elements combine with bacteria present in the mouth and produce a sticky kind of film on the teeth - this is called plaque.  Plaque is often found on the chewing surfaces of the back teeth, an area a toothbrush does not easily reach.   Even flossing is sometimes ineffective.  If plaque is not removed regularly from the teeth, it can produce acids which attack the tooth enamel and create cavities in the tooth.  This leads to tooth decay.

The other way of explaining and preventing plaque is :

It is known that bacteria in dental plaque uses the nutrients in sugary type foods to produce acids. (Dental plaque is discussed in chapter 5, “Oral Pathology,” and in Dental Technician, Volume 2, chapter 3, “Preventive Dentistry.“) Foods that contain carbohydrates (high sugar content) are referred to as being cariogenic (conducive to the production of dental caries). Dental caries may start when poor oral hygiene is present. The decay process begins when dental plaque and the acid produced from cariogen foods are left on the teeth for extended periods. Eventually, the acid demineralizes or breaks down enamel and dentin. To reduce the possibility of dental decay, you should limit the ingestion of sweets to mealtime, and brush and floss thoroughly after meals. Some of the less cariogenic snack foods include fruits and vegetables. However, the least cariogenic snack foods are limited to skim milk, sugar free gum, sugarless soft drinks, sugarless gelatins, and a few others. Ideally, caries may be avoided by properly brushing and flossing right after eating.
