A total of 172 patients referred to the Norwegian National Adverse Reaction Group were patch‐tested with a dental series. Of these, 25% showed a positive reaction to gold sodium thiosulfate or potassium dicyanoaurate. There was a statistically significant correlation ( p =0.0019) between the presence of dental gold and a positive patch test to gold. There was a statistically significant correlation between ear piercing and a positive patch test to gold ( p =0.04). In most cases, we did not find clinical correlates to positive patch tests to gold. 2 patients with objective and subjective oral/perioral and general symptoms are described as case reports. Their symptoms disappeared when gold restorations were removed. We conclude that there is an overrepresentation of gold allergies among those with dental restorations containing gold.
