Armed with Ötzi's newly sequenced genome and a detailed dental analysis, scientists have also found that the Iceman had brown eyes (not blue, as commonly assumed) and probably wasn't much of a tooth brusher. Dental analysis shows that the Iceman suffered a blunt force trauma to two teeth — possibly a blow to the mouth — at least several days before his death and was plagued by both periodontal disease and cavities."
