What is a main cause of facial erosion of teeth?

Facial erosion of teeth is primarily caused by the exposure to acidic substances, making acidic beverages a main contributor. Drinks such as soda, fruit juices, and sports drinks contain high levels of acids, which can wear away the enamel on the teeth over time. This process is known as dental erosion and occurs when the pH level of the mouth drops due to acid exposure, leading to the demineralization of the tooth structure.

In contrast, while excessive brushing may contribute to tooth wear, it is more commonly associated with abrasion or wear rather than erosion. Genetic conditions can impact susceptibility to enamel development but are not direct causes of erosion. Similarly, dental trauma can lead to physical damage to the teeth but does not typically result in the erosion of enamel due to acid exposure.
