Often these conditions result from abnormal excessive behaviour.  

These conditions often result from excessive abnormal behaviour.  

Excessive wear will often result in exposure of the [[Enamel Organ#Pulp|pulp cavity]]. If the wear is gradual, the pulp may respond by laying down more [[Enamel Organ#Dentin|dentine]] – reparative dentine (also known as tertiary dentine).  

Excessive wear can often result in exposure of the [[Tooth - Anatomy & Physiology#Pulp|pulp cavity]]. If the wear is gradual, the pulp may respond by laying down more [[Tooth - Anatomy & Physiology#Dentin|dentine]] – reparative dentine (also known as tertiary dentine).
