Dental plaque is a soft deposit that forms on the surface of teeth. It contains many types of germs (bacteria). You can usually remove plaque quite easily by tooth brushing and cleaning between teeth.

Excerpt: Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth. It appears as a white/pale yellow “slime layer,” that is commonly found in between the teeth and along the cervical margins. Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm or bacterial plaque biofilm.While plaque is commonly associated with oral diseases such as caries and periodontal diseases (gum diseases), its formation is a normal process that can’t be prevented.
