http://www.cnn.com/2014/07/03/health/tooth-decay-causes/ http://www.cnn.com/2014/07/03/health/tooth-decay-causes/ > About 60% of the risk for tooth decay appears to be due to genetic factors, says Mary L. Marazita, director of the Center for Craniofacial and Dental Genetics at the University of Pittsburgh School of Dental Medicine. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3267319/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3267319/ > Twin studies provide the opportunity to dissect the relative contribution of genetics and environment on dental caries variation. Accordingly, these studies can often suggest, but not prove, biological inheritance. Current evidence supports the notion that there is an inherited variation in enamel development that is associated with increased occurrence of dental caries. At present, these results are limited to specific populations with overt recognizable syndromes. http://www.utimes.pitt.edu/?p=19115 http://www.utimes.pitt.edu/?p=19115 > Personal habits, fluoride and genetic factors all play a role in the development of cavities. Age is a factor as well, said Vieira, who has devoted some of his research to uncovering which genes have an influence.
