What is the primary condition that dental caries are known to cause?

1. Tooth loss

2. Tooth decay

3. Gum disease

4. Teeth staining

The correct answer is: Tooth decay

Tooth decay is the primary condition associated with dental caries. Dental caries, commonly known as cavities, are the result of the breakdown of tooth structure caused by acid-producing bacteria that feed on sugars and starches in food. When these bacteria metabolize sugars, they produce acids that erode the enamel, leading to cavities and eventually causing decay. Tooth loss can occur as a result of untreated tooth decay, but it is a subsequent condition rather than the primary outcome. Gum disease, while potentially related to overall oral health, is not a direct consequence of dental caries. Teeth staining is also not a direct result of dental caries but rather linked to dietary choices, hygiene, and other factors affecting overall tooth appearance. Thus, tooth decay is the most direct and primary condition that dental caries are known to cause.
