What does an enamel fracture primarily affect?

The root of the tooth
The inner pulp of the tooth
The outer protective layer of the tooth
The surrounding gum tissue

The correct answer is: The outer protective layer of the tooth

An enamel fracture primarily affects the outer protective layer of the tooth, which is the enamel. This hard, outer layer is crucial for protecting the underlying structures of the tooth, including the dentin and the pulp. When an enamel fracture occurs, it compromises this protective barrier, which can lead to increased sensitivity, a higher risk of tooth decay, and potential exposure of the underlying layers to external stimuli, such as temperature changes and bacteria. Understanding that enamel is the first line of defense for teeth helps underscore the importance of maintaining its integrity to prevent further dental complications.
