उत्तर

  • Enamel Erosion: Plaque bacteria turn food sugars into acids, which dissolve enamel and create cavities.
  • Gingivitis: Toxins from plaque irritate the gums, causing swelling, redness, and bleeding.
  • Periodontitis: Chronic gum inflammation eventually damages the jawbone, causing teeth to become loose.
  • Tartar Hardening: Minerals in saliva cause plaque to calcify into hard tartar, which only a dentist can remove.
  • Halitosis: Waste products from multiplying bacteria cause chronic bad breath.
