The World Health Organization notes that 60% to 90% of children and nearly 100% of adults have a history of dental caries. The caries process begins with the action of organic acids, which are produced by bacteria found in organized dental plaque via the anaerobic metabolism of dietary sugars. When this dental plaque goes undisturbed, organic acids may initiate the early stages of demineralization. Demineralization gradually weakens the tooth structure, making it more susceptible to plaque formation and demineralization. Remineralization is the process by which the damage to these surfaces is repaired by replacing surface minerals utilizing therapies such as fluoride, casein phosphopeptide, calcium phosphate and, even, eggshells. An evidence-based approach must be taken when evaluating the effects of these products.
