Question

Quizplus · Accepted Answer

As we age, the size of the pulp chamber in our teeth reduces, and our body starts depositing secondary dentin to protect the teeth. Both of these factors can cause teeth to darken and become more brittle. Large caries can also contribute to the weakening of the tooth structure, but it is not the primary cause of darkening and increased brittleness with aging.
