Fri 08 Aug 2003Less than 50% go on routine visits to dentistLess than half the population routinely visit the dentist and the poor go much less regularly than the wealthy, according to a new survey.It was published yesterday as part of a campaign supported by the Irish Dental Association to improve dental health. Dentists recommend that people change their toothbrush three times a year. The Irish change theirs only once a year, less than the British but more than the Spanish who buy a new toothbrush only 0.7 times a year.
