Dental abrasion is
tooth wear originating from friction or mechanical forces from a foreign object, and it predominantly impacts premolars and canines. Tooth wear from abrasion typically looks like a wedge or V-shaped indentation of the tooth at the gum margin, and it appears worn, shiny and is often discolored at the cervical margin.
Dental abrasion is the result of external mechanical action on the teeth removing the tooth enamel. Erosion occurs when acids in food or from the stomach dissolve the enamel surface of the teeth. Most often found on the tongue side of the upper teeth.
