Many adults experience significant dental problems that could be prevented through basic oral hygiene practices, like regular dentist appointments. For example, in 2009 alone, CDC data indicated that only 62 percent of adults surveyed had visited the dentist. To maintain optimal oral health, adults should brush their teeth at least twice a day, preferably after each meal and before going to bed. Flossing is also an essential part of an adult’s daily oral hygiene regimen. Regular brushing and flossing can prevent unpleasant conditions, such as plaque and bad odor. However, over-brushing or flossing may result in mouth bruises and bleeding, which can lead to infections. Adults should visit their dentist regularly for routine check-ups and before using over-the-counter medication.
