Ancient Vikings Had Advanced Dental Practices Revealed by X-Ray Studies
Contrary to popular belief, a recent study on Viking teeth from Sweden has uncovered evidence of advanced dental practices among this ancient population. While caries and toothaches were prevalent, X-ray analysis revealed signs of dental work and modifications, challenging stereotypes about ancient dental care.
Conducted by the University of Gothenburg’s Institute of Odontology, the study examined 3,293 teeth from 171 individuals in the Viking Age population of Varnhem, Västergötland. The analysis, utilizing modern dentistry tools and X-rays, provided insights into the dental health and practices of Vikings in that region.

According to the findings published in the journal PLOS ONE, nearly half of the Viking population studied exhibited cavities, with adults showing a 13% prevalence of caries, often affecting the roots. Interestingly, children with milk teeth were cavity-free, indicating a different diet pattern compared to adults.

Intriguingly, the study also revealed evidence of tooth modifications by Vikings, such as tooth filing, the use of toothpicks, and dental treatments for infected teeth. Molars with filed-down holes from crown to pulp were identified, suggesting a form of ancient dental surgery to alleviate pain and infection.
Carolina Bertilsson, a dentist and Associate Researcher involved in the study, remarked, “The Viking’s dental practices show similarities to modern dental treatments, indicating a level of knowledge and skill in dealing with dental issues.”
