      From the archaeological site at Skeljastadir in Thjorsardalur, 915 teeth in 49 skulls were availible for evaluation, 24 female, 24 male and one with undetermined sex. Two methods were used to evaluate tooth wear. The first according to the classification: 0. no wear, 1. wear in enamel, 2. dentin exposed, 3. exposure of pulp cavity. The second method was based on Brothwell´s thirteen wear stages. For age estimation five methods were used based on devlopmental stages of teeth, one on tooth wear and one of ectocranial suture closure. The adult skeletons were sexed using morphological characteristics from skull, mandible and in few instances pelvis. There was significantly more (p < 0.001) wear in the older age groups than in the younger groups and no significant difference between sexes. The highest score of wear was on first molars, which also had the highest prevalence of root abcesses, and the lowest score was on third molars. Tooth wear seen in the Skeljastaðir population has all the similarities seen in wear from coarse and rough diet. But in some instances it has similar characteristics as seen in erosion in modern Icelanders consuming excessive amounts softdrinks and other acidic beverages. A mixture of acidic whey and water was a daily drink in Iceland until the 20th century and whey was used for preservation of food. The consumption of acidic drinks and food in addition to coarse diet has likely played a sizable role in the dental wear of the Skeljastaðir population.
