Dental Plaque

Plaque is a sticky film of bacteria that constantly forms on teeth. Bacteria in plaque produce acids after you eat or drink. These acids can destroy tooth enamel and cause cavities and gingivitis (gum disease).

Components of plaque

Early biofilm: primarily Gram-positive cocci.

Older biofilm (3–4 days): increased numbers of filaments and fusiforms.

4–9 days undisturbed: more complex flora with rods, filamentous forms.

7–14 days: Vibrio species, spirochetes, more Gram-negative organisms.

Bacteria are in dental plaque

  • Streptococcus mutans is the main cause of dental decay. Various lactobacilli are associated with progression of the lesion.
