Dental amalgam and multiple antibiotic resistance: an untested hypothesis

In a recent article in your journal, Summers et al. (3) suggested that exposure to mercury (Hg) from dental amalgams resulted in an increased incidence of multiple antibiotic-resistant bacteria in the normal floras of nonmedicated subjects. However, the study does not allow such conclusions, and the authors' inferences are unwarranted. The investigators first reported the results of a study that attempted to correlate the incidence of Hg resistance with that of antibiotic resistance in human fecal flora. This study
