What is tooth plaque?
Plaque is a sticky mix of bacteria and the substances they secrete. Bacteria produce adhesive chemicals called mucopolysaccharides. The bacteria then live in this film on teeth, called a biofilm. At first, this slimy layer is fragile and easily removed by tooth brushing. “Think of the film on a fish tank wall. It’s easy to wipe off with a washcloth, if you’re vigilant,” says Price. And if you’re not? The bacteria in tooth plaque are free to release acids that damage tooth enamel. Regular acid assaults on enamel can wear holes in teeth, commonly called cavities. If left alone, plaque buildup also gradually hardens, creating tartar or calculus on your teeth. “Tartar is petrified plaque,” Price tells WebMD. “Once it’s there, you need a dentist’s help…tartar can’t be brushed off.” Tartar above the gum line also contributes to gingivitis, or gum disease. The secrets to avoiding plaque buildup aren’t so secret. You’ve probably been hearing most of them since before you lost your baby teeth.
