Biological factors

There are several biological factors related to erosion. The most important ones are properties and characteristics of saliva and teeth. In addition, differences in the anatomy of soft tissues, soft tissue movements (tongue and buccal mucosa) and swallowing patterns can influence the risk of erosion by controlling the retention or clearance patterns of erosive agents (Lussi & Jaeggi 2008).

Let’s look at these three main biological factors related to erosion in more detail:
