There is a ready market for old dental fillings, crown, and bridges of gold by companies who have refining capabilities. Dental fillings are gold alloys (gold combined with other metals). One gram equals 5 carats and one ounce equals 141.75 carats. Most dental fillings contain 10 to 22 carats of gold.
