Plaque (Dental)

Plaque (Dental) is a soft, colourless or pale-yellow biofilm composed of bacteria, food debris and saliva that constantly forms on tooth surfaces and around the gumline. It develops when bacteria feed on sugars and fermentable carbohydrates from the diet, producing acids that can demineralise tooth enamel and irritate gum tissue.

If plaque is not removed regularly by brushing and interdental cleaning it can harden into tartar (calculus), which requires professional removal and raises the risk of cavities and gum disease such as gingivitis and periodontitis. Prevention focuses on twice-daily brushing with fluoride toothpaste, daily flossing or interdental cleaning and regular dental check-ups and professional cleans to control plaque buildup.
