Dental erosion is the loss of dental hard tissues caused by non-bacterial acids. Due
to acid contact, the tooth surface becomes softened and more prone to abrasion from
toothbrushing. Dentifrices containing different active agents may be helpful in
allowing rehardening or in increasing surface resistance to further acidic or
mechanical impacts. However, dentifrices are applied together with brushing and,
depending on how and when toothbrushing is performed, as well as the type of
dentifrice and toothbrush used, may increase wear. This review focuses on the
potential harmful and helpful effects associated with the use of dentifrices with
regard to erosive wear. While active ingredients like fluorides or agents with
special anti-erosive properties were shown to offer some degree of protection against
erosion and combined erosion/abrasion, the abrasive effects of dentifrices may
increase the surface loss of eroded teeth. However, most evidence to date comes from
in vitro and
in situ studies, so clinical trials
are necessary for a better understanding of the complex interaction of active
ingredients and abrasives and their effects on erosive tooth wear.
