Six Dental Myths That Can Hurt Your Smile

Dental advice gets repeated for years even when it is incomplete. Here are six beliefs we regularly clarify with patients in our Lilburn office.

Myths about cavities

Myth: If a tooth does not hurt, it is healthy. Early cavities and gum disease are often painless. Myth: Only sugar causes cavities. Bacteria also use starches, and frequent snacking keeps the mouth acidic longer.

  • Sugar-free does not always mean acid-free
  • Baby teeth still need treatment and prevention
  • A filling cannot repair itself once decay creates a hole

Myths about daily care

Myth: Bleeding means you should stop flossing. Usually it means inflamed gums need more consistent, gentle cleaning. Myth: Brushing harder cleans better. Heavy pressure can wear enamel and contribute to recession.

  • Use soft bristles
  • Brush for two minutes, not with extra force
  • Clean between teeth once each day

Myths about whitening

Myth: Every stain will whiten. Crowns, fillings, and veneers do not change shade, and internal discoloration may need a different cosmetic approach. An exam helps identify the safest option.
