What is oral biofilm?

Oral biofilm is a structured community of micro-organisms that attaches to surfaces in the mouth. This plaque consists of hundreds of bacterial species working together within a protective matrix. Biofilm forms continuously and can return within 24 hours of cleaning. It is the primary cause of gum inflammation and tooth decay. As the biofilm ages, it becomes more harmful to oral health. Professional cleaning removes hardened biofilm (tartar) that can no longer be removed by brushing. Home care with brushing, flossing and interdental brushes disrupts the daily formation of biofilm. Special mouthwashes can help to inhibit bacterial growth. A healthy mouth has a balanced biofilm without dominant harmful bacteria. Regular check-ups with the dental hygienist are essential for keeping biofilm under control.
