Attrition is the loss of tooth structure that develops from tooth to tooth contact, usually from grinding or the result of a malocclusion where the teeth bite together incorrectly. Attrition occurs primarily on the chewing surfaces of the teeth.

The changes resulting from tooth attrition can range from small points of increased wear on the edge or chewing surface to a reduction of the entire tooth height and flattening of the chewing surfaces, cusps or incisal edges.

Attrition can also be influenced by the texture of foods you eat, gum chewing, use of tobacco products, or bruxism, an abnormal clenching and grinding of the teeth, or even abrasive dust in the atmosphere.

Treatment options

• Correcting the malocclusion (bad bite) with orthodontics or selective tooth modification.
• Using a night guard- a soft plastic device worn over the teeth during sleep to protect the teeth and prevent clenching and grinding.
• Eliminating any habits that may be contributing to the condition.
• Restoring the appearance, strength and function of teeth with bonded fillings or crowns.
