There are two main types of teeth stains:
extrinsic and intrinsic.

  1. Extrinsic Stains:
    Extrinsic stains are like splatters of paint or dirt
    on the teeth. It originates from external sources that come into contact with your teeth. The most common cause include:
  • Food and Drinks:
    The dark pigments found in coffee, tea, red wine, berries, and even soy sauce can stain your
    teeth over time. These chromogenic (color-producing) compounds stick to
    the enamel, the hard outer layer of your teeth.
  • Smoking and Tobacco Use: Tobacco products like cigarettes, cigars, and chewing tobacco contain tar and nicotine, which stain teeth a
    yellowish-brown color. These stains can be particularly stubborn and difficult to remove.
  • Poor Oral Hygiene: Plaque, a sticky film of bacteria that forms on teeth, can trap food particles and stains, further contributing to discoloration.Brushing and flossing regularly are essential to prevent plaque buildup and maintain a bright smile.The good news is that extrinsic stains are often the easiest to address.Regular brushing with a fluoride toothpaste can remove surface stains.Professional teeth cleanings from your dentist can tackle more stubbornbuildup and leave your teeth feeling sparkling clean.
  • Intrinsic Stains:Unlike extrinsic stains, intrinsic stains originate from within the tooth itself.They can be more challenging to remove and may require professionalintervention. Here are some common causes of intrinsic stains:
  • Medications:
    Certain medications, particularly tetracycline antibiotics used during childhood tooth development, can stain teeth a gray or brown
    color. Other medications, such as antihistamines and certain blood pressure medications, can also contribute to discoloration.
  • Trauma:
    Injury to the tooth, such as a fall or blow to the face, can damage the pulp (the inner part of the tooth) and lead to discoloration.
  • Genetics: The thickness and translucency of tooth enamel can be influenced by genetics. Some people naturally have thinner enamel, which can make the underlying dentin (a yellowish-brown tissue beneath the enamel) more visible, leading to a darker appearance.
  • Aging: As we age, the enamel on our teeth can naturally thin, allowing the underlying dentin to show through and contribute to a yellowish cast.
  • Additionally, the accumulation of dentin over time can also darken teeth. As we have seen, traditional methods may not be enough to combat deep stains or discoloration.
