December 31/Chicago/Pharma Law Weekly -- Elevated dental plaque acid is a risk factor that contributes to cavities in children, but eating bran flakes with raisins containing no added sugar does not promote more acid in dental plaque than bran flakes alone, according to new research at the University of Illinois at Chicago.
Some dentists believe sweet, sticky foods such as raisins cause cavities because they are difficult to clear off the tooth surfaces, said Christine Wu, professor and director of cariology research at UIC and lead investigator of the study.
