Abrasion is the result of repeated contact between a tooth and something hard, like teeth. So, when two or more teeth come together, even with regular chewing with an ideal bite, some abrasion will occur.
Abrasion, damage to the epidermis of the skin. Abrasions are caused primarily by friction against a rough surface, which removes the superficial skin layers. Although most abrasions are simply scrapes and are easily treated, large, very painful, or infected abrasions may require medical attention
Taber Test Methods: Taber Abraser (Abrader) - Taber Industries
Abrasion Resistance of Cloth: Rotary Platform, Double-Head (Taber) Method This method is intended for determining the abrasion resistance of cloths in terms of percent change in breaking strength, or breaking strength after a given period of abrasion, or the number of abrasion cycles required to produce a specified state of destruction.
The former case is generally known as two-body abrasion or low stress abrasion; the latter is known as three-body abrasion or high stress abrasion. High stress abrasion is generally regarded as the more severe, because it can induce fracture of the abrasive particles, thereby ensuring the presence of sharp edges for the cutting action.
Abrasion. A scrape off the surface of the skin (falling on a rough surface) Puncture. A deep, penetrating wound (a hole) likely caused by a nail and is most likely to cause infection because it has very little bleeding. Avulsion. A chunk of flesh or skin that is removed

Abrasion is a kind of wear in which rubbing away of component fibers and yarns of the fabric takes place. During abrasion, a series of repeated applications of stress takes place. Abrasion may be classified as flat abrasion, edge abrasion or flex abrasion. Abrasion resistance can be seen is the capacity to absorb energy.
Dermabrasion | American Society of Plastic Surgeons
Dermabrasion and dermaplaning help to "refinish" the skin's top layers through a method of controlled surgical scraping. The treatments soften the sharp edges of surface irregularities, giving the skin a smoother appearance. Dermabrasion is most often used to improve the look of facial skin left scarred by accidents or previous surgery, or to smooth out fine facial wrinkles.
What is Taber Abrasion? - Definition from Corrosionpedia
