Fact 4: AF Is Not a Lone Wolf
Abfraction does not occur in a vacuum. It’s part of a trio of tooth tissue loss conditions, alongside abrasion and erosion, collectively known as non-carious cervical lesions (NCCLs). These conditions may present separately but often occur concurrently, influencing and exacerbating each other. This interrelation complicates both the diagnosis and management of AF, requiring a nuanced understanding of each condition.
Abrasion refers to the mechanical wearing away of tooth structure from an external source, such as aggressive tooth brushing or the habit of holding objects between the teeth. Erosion, on the other hand, involves the chemical dissolution of enamel due to acids, whether from dietary sources like citrus and soda or from internal sources such as acid reflux.
The presence of abrasion and erosion can accelerate the progression of abfraction. For example, erosion can thin the enamel, making it more susceptible to the flexural forces that cause AF. Similarly, abrasion can weaken the tooth’s defenses, allowing abfraction lesions to form more readily.
Addressing AF effectively, therefore, involves managing not just the mechanical factors but also considering the chemical and behavioral aspects of oral health. This multifaceted approach can include dietary modifications, the use of acid-neutralizing mouthwashes, and the adoption of gentler oral hygiene practices.
Abfraction is not an isolated phenomenon but rather a part of a complex interplay of factors that contribute to tooth tissue loss. Recognizing and addressing this interconnectedness is key to preventing and treating AF, as well as preserving the long-term health and functionality of our teeth. (4)
