We are shockingly awful at brushing our teeth, a practice that most of us have been doing since before we were tall enough to see into the bathroom mirror.
According to a Swedish survey, just 10% of people use the ideal brushing method. In a poll of 2,000 people in the UK, the British health insurer Bupa discovered that over half of participants did not know how to wash their teeth properly.
According to Josefine Hirschfeld, an associate professor and specialist in restorative dentistry at the University of Birmingham in the United Kingdom, “it is highly likely that anyone who has not had formal instructions from their dentist or hygienist brushes incorrectly.” This will constitute the great majority of people in any nation, in my experience.
