What is biofilm?

Is a slimy covering composed of extracellular polysaccharides, structural proteins, cell debris and nucleic acids. Biofilm formation begins with bacteria entering the oral cavity and slowly forming a layer over the teeth. Dental biofilm is a risk factor for gingivitis, dental caries, periapical periodontitis, periodontitis, and peri-implantitis. The oral cavity provides a moist, warm, and nutritious environment to promote the growth of biofilm. Biofilm produces acid which de-mineralises tooth surface and increases the risk of caries. The bacteria biofilm contributes to conditions such as gingivitis and periodontitis as it causes and inflammation, infection and destruction of periodontal structures. A build-up of Biofilm shows what surfaces you may be missing when brushing.
