Have Your Next Tooth Filled Electrically!
NEXT year when you go to a dentist to have a tooth filled he may connect the cavity up to a small dynamo and fill your tooth electrolytically with gold or silver, in the same way that metal articles are gold or silver-plated.
Dentists are working along these lines because the prevailing method of making gold inlays involves the use of wax impressions, which frequently are slightly inaccurate, leaving unfilled pockets in the tooth as a source of future trouble. Cavities would be coated with chemically pure graphite as an electric conductor, filled with an electrolytic liquid bearing a solution of a gold salt, and the current turned on to deposit a perfect filling in the tooth.
