What is the primary cause of erosion in dental health?

The primary cause of erosion in dental health is acid exposure. Erosion occurs when acids wear away the enamel on the teeth, which is a protective outer layer. This acid may come from various sources, such as dietary acids found in soft drinks, fruit juices, and acidic foods, or it can be the result of gastric acids from conditions like acid reflux. The process of erosion can lead to increased sensitivity and decay if not managed properly.

Other factors like bruxism (teeth grinding) and mechanical wear contribute to tooth wear but are not the main causes of erosion, which specifically relates to the chemical action of acids. Similarly, while fluoride accumulation can strengthen enamel and protect against caries, it does not cause erosion itself. Understanding the role of acid exposure in dental health is crucial for prevention and management strategies in dental hygiene.
