Ever seen or feel cracks or sensitivity on teeth?? Thought about the reasons??

 DENTAL WEARS 

Dental attrition, abfraction, abrasion, tooth erosion and root resorption are different types of wear on teeth.

 But what exactly are they? What are their causes?

Dental abfraction : is a loss of tooth structure, usually due to continued trauma to the teeth caused by excessive force on them due to a bad bite. When tension zones are generated, microfractures are produced that in the long term can cause the loss of enamel, dentin and cementum.

Tooth abrasion:

Abrasion is a loss of tooth structure due to the contact of the teethwith abrasive elements, such as the use of a toothbrush that is too hard or brushing that is too aggressive.

Tooth attrition:

Attrition is wear of tooth surfaces due to contact between them. This process occurs frequently in bruxist or squeezing patients. 

Tooth erosion:

Erosion is the destruction of the tooth surface caused by external elements, usually chemicals and/or acids, such as those contained in carbonated beverages. An excessive consumption of them can cause the loss of enamel.

Esophageal reflux and bulimia:

In people with gastroesophageal reflux or those who suffer from bulimia, the frequent contact of gastric acids with the surface of the teeth, cause them to progressively erode.

Root resorption:

Root resorptions are defects in a tooth that can affect the enamel, dentin, cementum and pulp, usually caused by trauma, orthodontic treatment, cysts, impacted teeth, systemic, idiopathic or genetic diseases. Resorptions can be external or internal.
