Are college students more or less likely to brush their teeth than high schoolers?

According to the American Dental Association, college students are less likely to brush their teeth than high schoolers. A survey of 1,000 college students found that 35% of them brushed their teeth twice a day, compared to 45% of high school students. The survey also found that college students were more likely to skip brushing their teeth in the morning and at night, and were more likely to use mouthwash instead of brushing.
