What is intrinsic discoloration of teeth primarily caused by?

1. External factors

2. Diet and medication

3. Improper brushing

4. Trauma to the teeth

The correct answer is: Diet and medication

Intrinsic discoloration of teeth refers to changes in the color of the tooth structure itself, as opposed to surface stains caused by external factors. This type of discoloration is primarily the result of internal issues within the tooth, particularly related to the development of the tooth and factors that affect its structure. Diet plays a significant role, as certain foods and beverages can have an impact on the condition of the teeth during their formation. Additionally, medications such as tetracycline, when taken during certain developmental stages, can cause intrinsic stains that become part of the tooth structure. These internal factors can lead to a permanent alteration in color, making diet and medication critical contributors to intrinsic discoloration. Understanding intrinsic discoloration helps in dental diagnosis and treatment planning, as it identifies the source of the problem as being deeply rooted within the tooth rather than just on the surface, which would be addressed differently in dental care.
