These forms of tooth wear can further lead to a condition known as abfraction, [3] where by tooth tissue is 'fractured' due to stress lesions caused by extrinsic forces on the enamel. Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. [ 3 ]
The primary cause of enamel wear in the grooves is the direct mechanical forces applied during chewing, such as vertical pressure and lateral forces as teeth grind or shear food. Particularly in areas where food is more frequently trapped or where contact is poor, the continuous friction between the food and the tooth surface causes abrasion ...
The white opaque areas in the enamel of the teeth are more extensive but do involve as much as 50% of the tooth. Moderate: 4: All enamel surfaces of the teeth are affected and surfaces subject to attrition show wear. Brown stain is frequently a disfiguring feature Severe: 5: All enamel surfaces are affected and hypoplasia is so marked that the ...
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.

Demineralization occurs for several reasons, but the most important cause of tooth decay is the ingestion of fermentable carbohydrates. [citation needed] Tooth cavities are caused when acids dissolve tooth enamel: [22] Enamel is also lost through tooth wear and enamel fractures.
