Dental gold is one of the most popular forms of gold used for recycling and earning extra cash. When dentists work on patients, they often remove old gold teeth, fillings, bridges, and crowns. Often these gold scraps are thrown into a drawer and kept safe, but dentists never get around to doing anything with the gold. With gold prices being high currently, some dentists send the scrap gold to a professional team of metallurgists. They weigh the gold once other minerals have been removed from it, and compensate the customer at fair market value.
