What do you call loss of tooth structure due to bruxism?
A
attrition
B
supernumerary
C
abfraction
D
tooth decay
Explanation: 

Detailed explanation-1: -TSL is observed clinically as attrition, abrasion, abfraction, and erosion.

Detailed explanation-2: -The most common causes of tooth abfraction are as follows: Teeth Grinding (Bruxism) – Teeth grinding refers to the gnashing, clenching, and shifting of the teeth when a person is asleep. This can place an undue amount of stress and pressure on the teeth, resulting in the formation of abfraction.

Detailed explanation-3: -An abfraction is an angular notch at the gumline caused by bending forces applied to the tooth. An abrasion is a rounded notch at the gumline that may be visibly indestinguishable from an abfraction, although in cross-section abrasions are generally not as angular and have more of a saucered appearance.

Detailed explanation-4: -Dental attrition is the loss of tooth structure or tissue caused by tooth-on-tooth contact. Although this type of tooth wear is considered part of the normal aging process, more rapid dental attrition may be due to larger dental problems.
