Dental decay (caries) and periodontal (gum) disease are among the most common diseases afflicting mankind, especially in the so-called advanced nations.

If it is possible to cleanse the mouth completely of the bacterial plaque and maintain it that way, there would be low incidence of tooth decay or any other gum problems.

Dental diseases are not considered to be lethal and therefore attitudes on the part of governments and public are of a different nature. However, the cost of dental disease in pain, suffering, treatment and loss of work is enormous. Measures to reduce or eliminate dental problems would result in a vast benefit to the population.
