The relationship between incisal/occlusal wear, dentine hypersensitivity and time after the last acid exposure in vivo

Occlusal tooth surfaces suffer erosive, attritive and abrasive tooth wear. Tooth wear is important in the aetiology of dentine hypersensitivity on these surfaces. Dentine hypersensitivity is more likely initiated if subjects consume acidic beverages more recently. This supports clinically the episodic nature of dentine hypersensitivity caused predominately by active erosive tooth wear.
