Dental plaque is a complex biofilm containing several hundred different species of bacteria. While these are normally harmless commensals, shifts in the population structure can lead to the plaque-related diseases such as dental caries and periodontal disease. Surface polysaccharides are important in coaggregation reactions that bind particular species together and aid colonisation and metabolic interaction while sucrose-derived glucans and fructans have a significant effect on plaque properties. Fructans serve as an extracellular energy store while glucans contribute to adhesion, modify the permeability of plaque and alter ion-binding capacity and thus have a powerful influence on the creation of conditions in plaque that can lead to dental caries.
