Abrasion (Dentistry)

Abrasion means mechanical grinding. This is a pathological process of tooth tissue loss that affects the area of the corona dentis ("wedge-shaped defect") of the canine and premolar caused by an extraordinary mechanical influence. Extraordinary mechanical influences include:

bad brushing technique ;
prosthesis pressure;
toothpastes with an abrasive effect (cause surface [[enamel] defects );
bad habits;
hard toothbrushes (they cause wedge-shaped defects on the necks of the teeth during the horizontal tooth cleaning technique);
genetic predisposition;
occupational disease (glaziers).

As a result of long-term abrasion, there is a gradual loss of hard dental tissues, which manifests itself in increased sensitivity of the teeth. In the case of wedge-shaped defects, there is also a risk of exposing the pulp and breaking off the crown.
