Dental plaque is a solid, sticky mass of bacteria associated with sugar. Dental plaque can not be washed off, but can be removed with a brush. Dental plaque is responsible for most dental problems. Dental plaque main feature is the grip even on smooth surfaces of teeth which helps him in the presence of the acquired pellicle. Interestingly, the pellicle formed on the tooth surface within minutes of polishing, created from saliva and form a very thin film that coats the teeth. Development of Dental plaque then advancing rapidly. Up to 10 million different bacteria mm2 can cover the surface of the teeth an hour after cleansing, in which the bacteria inhabit the surface of the tooth perfectly exact order of appearance. First occurs Streptococcus mutans, which creates a certain type of sugar in the form of the matrix network and thus are triggering early colonization. After that follows a chain reaction in which a large number of bacteria are involved. This is associated with an increased number of leukocytes in the area of the gums.
