Seven female subjects diagnosed with multiple sclerosis were tested for hearing at threshhold frequencies of 250, 500, 1000, 4000 and 8000 hz. The subjects then had their silver dental fillings (amalgams) removed. Between six and eight months after amalgam removal, testing for hearing was repeated. Six of the seven subjects showed improvement in hearing of the right ear and five of the seven showed improvement in the left ear. Four of the six frequencies tested in the right, ear improved significantly and three of six improved significantly in the left ear. The total frequencies were averaged before amalgam removal and compared to after amalgam removal. Hearing improved an average of 8 dB (p=0.02).
