Intrinsic Tooth Discoloration

Intrinsic tooth discoloration is a common dental issue that can affect the color of your teeth from the inside. Unlike extrinsic discoloration, which is caused by external factors like coffee or tobacco, intrinsic discoloration occurs within the tooth itself. In this article, we’ll explore the different types, causes, symptoms, diagnostic tests, treatments, and drugs associated with intrinsic tooth discoloration, using simple and accessible language.

Types of Intrinsic Tooth Discoloration:

  1. Genetic Discoloration: Some people inherit tooth discoloration from their parents.
  2. Tetracycline Stains: Antibiotics like tetracycline, when used during tooth development, can lead to permanent stains.
  3. Dental Fluorosis: Excessive fluoride intake during tooth formation can result in discolored enamel.
  4. Amelogenesis Imperfecta: This is a genetic condition where tooth enamel doesn’t develop properly, leading to discoloration.
  5. Dentinogenesis Imperfecta: Another genetic condition, where the inner tooth layer (dentin) forms abnormally, causing discoloration.
  6. Trauma-Related Discoloration: Injury to a tooth can damage the pulp and cause discoloration.
  7. Age-Related Discoloration: As we age, our teeth naturally become more yellow or gray due to changes in dentin.
  8. Medication-Induced Discoloration: Some medications, such as antipsychotics, can cause intrinsic tooth discoloration.
  9. Systemic Conditions: Certain medical conditions, like jaundice or hemochromatosis, can affect tooth color.
  10. Radiation Therapy: Patients who undergo head or neck radiation therapy may experience tooth discoloration.
