A national study conducted by the American Dental Association (ADA) in May 2012 (the National Oral Health Quiz) resulted in some surprising statistics. The results and the study were launched on one of ADA’s new websites called
On average, Americans scored a “D” on a series of true/false questions! How do you think you’d score on a quiz about your oral health? Well, we would like to share how some Americans scored on this particular quiz.
Here are some important highlights from the national ADA survey, using a sample of approximately 1,500 adults (with a margin of error of + or – 2.6 points):

  • 90% of participants mistakenly believe they should brush after every meal; the ADA recommends brushing your teeth twice a day.
  • 65% of respondents mistakenly believe they should only replace their toothbrush twice a year; the ADA recommends replacing your toothbrush once every 3 months.
  • 75% of respondents do not know what age their child should see the dentist for the first time; the ADA recommends taking your child to the dentist within 6 months after the first tooth appears, or no later than the child’s first birthday.
  • 81% of respondents mistakenly think that sugar causes cavities; actually, it’s the germs in the mouth that feed on sugar and then produce acid that attacks tooth enamel. The acids, over time, will weaken the tooth enamel to the point where a cavity forms.
  • 59% of respondents do not realize that cavity-causing germs can be passed from person to person.
  • 67% of respondents think that refined sugars produce more harm to the teeth than natural sugars. Actually, all sugar can promote tooth decay. Depending on the frequency of exposure, the risk of tooth decay increases.
  • 53% of respondents think they should floss 2 times per week; the ADA recommends that you should floss once a day. Since tooth brushing does not clean between the teeth, germs grow there, which can cause tooth decay and gum disease (or periodontal disease).

Pretty interesting statistics, right? We thought so, too!
