What term describes the loss of tooth tissue caused by grinding?

The term that describes the loss of tooth tissue caused by grinding is attrition. This process specifically refers to the wear and loss of enamel due to the mechanical action of opposing teeth grinding against each other, often resulting from bruxism (the habitual grinding or clenching of teeth). Over time, this can lead to a decrease in tooth height, sensitivity, and, in severe cases, can expose the underlying dentin.

It is important to differentiate attrition from other terms related to tooth tissue loss. Abrasion typically refers to the loss of tooth structure caused by external factors, such as aggressive brushing or using a hard-bristled toothbrush. Caries pertains to tooth decay caused by bacterial action, leading to cavities, while erosion is the loss of tooth enamel due to acid, often from dietary sources or acid reflux, rather than a mechanical process. Understanding these distinctions helps clarify why attrition is the correct terminology for tooth loss due to grinding.
