Staining Review by Color and Origin

We have all probably tried to drink our coffee and even wine through a straw to avoid staining our teeth, but what else can cause stains? And can stains be removed? Let’s discover how we can use the color and pattern of stains to discover how they occurred and whether they can be removed.

Staining by Color

The color of the stain tells a lot about how the discoloration occurred:

  • Orange-red: chromogenic bacteria, chromic acid/copper chemicals
  • Yellow: heavy dental biofilm/calculus
  • Green: Nasmyth’s membrane (thin tissue on newly erupted teeth), copper/nickel chemicals
  • Blue: dentinogenesis imperfecta, dentin dysplasia
  • Brown spots: potential carious lesions, fluorosis
  • Brown: chlorhexidine, tobacco, food (e.g., red wine, tea, coffee), stannous fluoride
  • Black: iron/silver/manganese chemicals, betel leaves
  • Grey: pulp necrosis, amalgam restoration
  • White: demineralization, fluorosis
  • Bands of dark colors: tetracycline
