Tooth attrition is the loss of tooth structure that can result from tooth-to-tooth contact during biting or chewing. It occurs primarily on the the biting or chewing surfaces of teeth, but it can also occur on what we call the proximal areas, where the teeth are in contact with adjacent teeth. The changes resulting from tooth attrition can range from small points of increased wear to a reduction of the tooth's height and a flattening of the chewing surfaces (the cusps). Generally, tooth attrition is more pronounced in older people, and it often shows up as smooth, polished surfaces on the tooth. The condition can be influenced by the texture of the foods you eat, gum chewing, use of tobacco products, orbruxism, an abnormal clenching and grinding of the teeth. Attrition can also be caused by abrasive dust in the atmosphere. The attrition can be severe if you suffer from amelogenesis imperfecta or dentinogenesis imperfecta - conditions in which the tooth's enamel or dentin do not form properly.
* Eliminating any habits which may be contributing to the condition, including tobacco use.
