Biofilm

Dental plaque is a biofilm that adheres to the surface of teeth. Biofilms are an accumulation of microorganisms that also contain bacterial cells that can infect gum and bone tissues. Colonies of these microorganisms adhere and develop stronger bonds over time on the surface of the tooth. Plaque can cause periodontal disease and needs to be scraped off by a dentist at least once year or more.
