Abrasion (dental)

Abrasion (dental)

Abrasion is the loss of tooth structure by mechanical forces from a foreign element. If this force begins at the cementoenamel junction, then progression of tooth loss can be rapid since enamel is very thin in this region of the tooth. Once past the enamel, abrasion quickly destroys the softer dentin and cementum structures.

Possible sources of this wearing of tooth are toothbrushes, toothpicks, floss, and any dental appliance frequently set in and removed from the mouth. The appearance is commonly described as V-shaped when caused by excessive pressure during tooth brushing.

The teeth most commonly affected are premolars and canines.

In archaeology

Archaeologists utilize evidence of dental abrasion as indication of dietary and other health issues of prehistoric peoples. There are a number of examples [C.Michael Hogan (2008) "Morro Creek", The Megalithic Portal, ed. by A. Burnham [http://www.megalithic.co.uk/article.php?sid=18502] ] of cranial recoveries dating thousands of years before present, where abrasion of teeth are used to analyze age and lifestyle of prehistoric peoples.
