Dental attrition is caused by tooth to tooth contact forming acquired wear facets upon pristine enamel, whereas abrasion is caused by food and foreign body contact (e.g., tooth brushing) that may obliterate attrition wear patterns.

What is the difference between abrasion and attrition?
Both abrasion and attrition refer to the wearing down of an object. ... However, attrition refers to the breaking off of particles (erosion) which occurs as a result of objects hitting against each other. Abrasion leads to surface-level destruction over time, whereas attrition results in more change at a faster rate.
What is attrition of the teeth?
Dental Attrition is a form of dental wear caused by tooth to tooth contact. The friction caused by teeth rubbing against each other can wear away the biting surfaces of the teeth.
How do you tell the difference between abrasion and Abfraction?
Difference between abfraction, abrasion, and erosion
- Abfraction. Abfraction is a wedge-shaped flaw on the tooth at the point it meets the gumline. ...
- Abrasion. Abrasion is likely to be found on the teeth closest to your cheeks, also known as the buccal side. ...
- Erosion. Erosion is the general wearing away of tooth enamel.
What does tooth abrasion look like?
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.
What are the two types of abrasion?
Abrasion may be classified as flat abrasion, edge abrasion or flex abrasion. Abrasion resistance can be seen is the capacity to absorb energy. It is the ability to resist wear from the continuous rubbing of fabric against another surface.
What is the process of abrasion?
Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction.
How is dental attrition treated?
In cases where the occlusion is severely altered by attrition, the only treatment choice may be a reconstruction with crowns and bridges. In the case of anterior wear, the loss of enamel at the incisal edge can lead to dentin exposure and the continuing loss of tooth structure due to slurry wear.
Is tooth wear normal?
Tooth wear is a very common condition that occurs in approximately 97% of the population. This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the incidence of non-carious tooth surface loss has also shown a rise.
What does attrition mean?
The term attrition refers to a gradual but deliberate reduction in staff numbers that occurs as employees retire or resign and are not replaced. ... Attrition happens for several reasons, including pay, lack of growth, and poor workplace conditions.
What is toothbrush abrasion?
Toothbrush abrasion is damage that is caused by brushing your teeth and gums too hard. Brushing your teeth every day is an important part of your dental care routine, but too frequent or too forceful tooth brushing can cause more harm than good, damaging your gums.
Can tooth abrasion be fixed?
Your dentist can repair some of the damage caused by abrasion using fillings. The dentist can apply the fillings to the grooves that form where your gum and tooth meet. The filling protects the area and keeps it free of bacteria and food particles.
What causes dental abrasion?
When you wear away your tooth enamel due to an external force, such as vigorous or aggresive brushing, nail biting, chewing on hard objects or using an abrasive toothpaste, your teeth undergo a process called dental abrasion.
