What Is Tooth Discoloration?
Tooth discoloration refers to any changes in the color of your teeth. Teeth may appear yellow, brown, gray, or even stained with spots. This condition occurs due to external or internal factors.
Types of Tooth Discoloration

Extrinsic Discoloration
Extrinsic discoloration affects the surface of the teeth. It often results from consuming staining substances like coffee, tea, or wine. Smoking and poor oral hygiene also contribute to these stains.
Intrinsic Discoloration
Intrinsic discoloration originates within the tooth. It may result from trauma, certain medications, or excessive fluoride exposure during childhood.
Age-Related Discoloration
As you age, enamel naturally wears down, revealing the yellow dentin beneath. This combination of extrinsic and intrinsic factors leads to discoloration over time.
Common Causes of Tooth Discoloration
1. Food and Drinks: Dark-colored beverages like coffee, red wine, and soda stain teeth over time.
2. Tobacco Use: Smoking or chewing tobacco leaves dark stains that are hard to remove.
3. Poor Oral Hygiene: Failing to brush and floss regularly allows plaque and stains to build up.
4. Medications: Antibiotics like tetracycline and doxycycline can cause intrinsic discoloration.
5. Fluorosis: Overexposure to fluoride in childhood can lead to white spots or streaks.
6. Aging: Thinner enamel exposes dentin, making teeth appear yellow.
7. Dental Trauma: Injuries can darken teeth due to internal bleeding or nerve damage.
How to Prevent Tooth Discoloration

– Brush your teeth twice daily using fluoride toothpaste.
