The 2014 Health Barometer provides insight into the oral hygiene practices of adults in metropolitan France. The Ministry of Health, the French National Authority for Health (HAS), and the French Union for Oral Health (UFSBD) recommend brushing teeth twice a day and visiting the dentist once a year. Among those aged 15–75, 71.1% report brushing their teeth twice a day, 25.1% once a day, and 3.8% less frequently. Adherence to this practice is significantly higher among women and those aged 15–24, and is influenced by cultural and social factors. Occasional smokers are more likely to brush twice daily; conversely, alcohol users at risk of dependence and those with chronic illnesses are less compliant, likely unaware that poor oral health increases the risk of chronic diseases. 63.7% of those aged 15–75 report having visited a dentist at least once in the past twelve months, compared to 56.2% in the 2010 Health Barometer. A positive finding: more than half of those who had no dental problems in the past year still made a dental visit; 54.9% of those who visited a dentist mentioned having their teeth scaled during their last visit. Good oral hygiene and annual dental visits are positively associated. Over the past twelve months, 15.5% of respondents had to forego dental care for financial reasons. The most socially and health-vulnerable populations are the hardest hit. [author’s summary]
