Tooth discoloration is a common dental concern that can significantly affect your confidence and how you interact with others. Although it is a widespread issue, many people do not understand the root causes of tooth discoloration. As such, this article aims to shed light on the reasons behind discolored teeth.
Types of Tooth Discoloration
Before delving into the causes, it’s important to identify the different types of tooth discoloration:
- Extrinsic: This discoloration affects the outer layer of the tooth, the enamel, and is usually caused by consumption of certain foods and beverages.
- Intrinsic: This type occurs when the inner structure of the tooth, the dentin, darkens or turns yellow.
- Age-related: Over time, the enamel can thin, allowing the dentin to show through, causing discoloration.
Causes of Extrinsic Tooth Discoloration
Various factors can lead to the discoloration of the tooth’s surface:
- Food and Drinks: Beverages like coffee, tea, wine, and dark sodas can stain teeth. Additionally, foods high in tannins, such as berries, can also cause discoloration.
- Tobacco Use: Tar and nicotine in tobacco products can lead to significant tooth staining.
- Poor Dental Hygiene: Failing to brush and floss teeth regularly can lead to plaque buildup and discoloration.
Causes of Intrinsic Tooth Discoloration
Intrinsic discoloration happens from the inside, often due to the following:
- Exposure to High Levels of Fluoride: While fluoride is essential for dental health, excessive exposure, especially in early childhood, can lead to discoloration.
- Enamel Hypoplasia: This condition, often due to malnutrition or a high fever during tooth development, can lead to discolored teeth.
- Tetracycline Antibiotics: If these antibiotics are given to children under 8 years old or to a pregnant mother, they can discolor the developing teeth.
Age-related Tooth Discoloration
Finally, age-related discoloration is an intrinsic process that happens over time due to the natural wear and tear of teeth, exposing dentin.
