HOSA Dental Terminology Practice

What does erosion refer to in dental terms?

1. A growth of new tissue

2. A loss of tooth structure

3. A type of tooth whiteness

4. A gum treatment

The correct answer is: A loss of tooth structure

Erosion in dental terms specifically refers to the loss of tooth structure. This process can occur when acids from food, beverages, or even from gastric reflux wear away the enamel, the hard outer layer of the teeth, leading to a reduction in the tooth's integrity. Over time, erosion can result in increased sensitivity, changes to the tooth's shape, and even tooth decay if the structure is compromised significantly. The other choices represent different dental concepts. The growth of new tissue pertains to tissue regeneration or healing processes in dentistry, but does not relate to erosion. A type of tooth whiteness is typically associated with whitening treatments or procedures that enhance the color of teeth, rather than a destructive process like erosion. A gum treatment would relate to periodontal health and care rather than the physical loss of tooth structure. Therefore, the definition of erosion as a loss of tooth structure aligns with how it is understood in the dental field.
