Abstract
The method for cleaning dental plaque biofilm from the teeth includes the steps of applying a liquid gellable composition to the teeth, the composition including a positively charged polymer such as chitosan, the liquid composition having a viscosity which results in coverage of substantially all of the exposed areas of the teeth. The liquid composition is then gelled by the addition of a second composition, such as a negatively charged compound. The resulting gelled composition has an adherence to the plaque biofilm which is greater than the adherence between the biofilm and the teeth. The gel layer with the biofilm is peeled off of the teeth, removing the dental plaque.
