Biofilm is a thin, slimy layer of germs that adhere to surfaces in the mouth, such as the tongue, gums and teeth. We all have oral biofilm, even the most avid brushers, flossers and rinsers, because the sticky film clings to nearly any surface that is wet. It happens in nature, too - think slippery rocks.
If you regularly brush, floss and rinse, you can minimise biofilm production. However, when brushing, flossing and rinsing habits are lacking, the biofilm can build and develop into dental plaque that you can see with the naked eye. It is usually pale yellow in color.
The thicker biofilm can cause gum irritation and spur the body’s inflammatory response. This will make gums appear red and swollen instead of their normal healthy pink and firm state. There may also be instances of plaque and tartar. If left untreated, this mild stage can progress into serious gum problems, called Periodontitis, which can infect the bone.
