According to two separate studies done by Pia Gabre and her colleagues at the Sahlgrenska Academy, University of Gothenburg, only one in ten brush their teeth in a way that effectively prevents tooth decay.

They studied the tooth brushing habits of 2013 Swedes aged 15-16, 31-35, 60-65 and 76-80 – how often and for how long, how often fluoride toothpaste is used, how much toothpaste is put on the toothbrush and how much water is used during and after the tooth brushing.  The results show that only ten percent of the population use toothpaste in the most effective way.

According to Pia Gabre,  most of the interviewed subjects learned to brush their teeth as children, by their parents, even if they have been informed about more effective techniques later in life, they continue to brush their teeth like they always have.
