Quizplus · Accepted Answer

Abrasion is the mechanical wearing away of tooth structure due to factors such as excessive or overly vigorous tooth brushing, which can lead to sensitive teeth, transparent edges near the gumline or notches. Attrition refers to the wearing away of tooth structure due to tooth-to-tooth contact or malocclusion. Erosion is the loss of tooth structure due to chemical dissolution by acids not of bacterial origin, such as those found in acidic foods and drinks or in stomach acid during acid reflux. Abfraction is a controversial concept that suggests that tooth structure loss can occur due to biomechanical stresses at the gumline in cases of cervical erosion, ablation, and abrasion.
