Trials were made in London with an apparatus for the extraction
of teeth by electricity!
The apparatus consisted of an induction-coil of extremely fine wire, having an interrupter that could vibrate at the rate of 450 times a second. The patient sat in the traditional arm chair and took the negative electrode in his left hand, and the positive in his right. At this moment, the operator turned on a current whose intensity was gradually increased till it had attained the utmost limit that the patient could support. The extractor was then put in circuit and fastened on the tooth, which under the action of the vibrations, loosened at once.
