Tooth Wear

Tooth wear (pronunciation: /tuːθ wɛər/) is a term used to describe the loss of tooth structure. The process is natural and occurs over time, but can be accelerated by certain factors such as diet, habits, and medical conditions.

Etymology

The term "tooth wear" is derived from the Old English words "tōth" meaning tooth and "werian" meaning to wear.

Types of Tooth Wear

There are three main types of tooth wear: abrasion, attrition, and erosion.

• Abrasion is the wear of teeth from external factors, such as improper brushing techniques or habits like chewing on pens or fingernails.
• Attrition is the wear of teeth due to tooth-to-tooth contact, often seen in individuals who grind their teeth, a condition known as bruxism.
• Erosion is the wear of teeth due to chemical processes, such as the consumption of acidic foods and drinks or conditions like gastroesophageal reflux disease (GERD).

Related Terms

• Dentin: The layer of the tooth beneath the enamel that can become exposed due to tooth wear.
• Enamel: The hard, outer layer of the tooth that can be worn away over time.
• Bruxism: A condition characterized by grinding or clenching the teeth, often leading to attrition.
• Gastroesophageal reflux disease (GERD): A medical condition that can lead to tooth erosion due to the regurgitation of stomach acid.
