Abrasion is the loss of tooth structure by mechanical forces from a foreign element. Brushing regularly is considered vital for healthy teeth and gums, but be warned, you cannot overdo a good thing. The people most at risk for tooth or gum damage from over-brushing are those who are very particular about their oral care but use faulty brushing techniques. Also in people who use medium- or hard-bristled toothbrushes or excessive pressure while brushing. Tooth abrasion can also be caused as a result of a combination of both these factors.
Vigorous brushing can wear down the enamel on the teeth as well as damage and push back the gums, exposing the sensitive root area. This can then lead to other dental problems such as gum disease and cavities on the roots of the teeth which may then require treatments such as fillings or root canals. To put it simply, brushing technique is vital to ensure cleanliness of teeth and you’re not going to achieve any extra benefit by brushing hard.
